Best Antibiotic Eye Drops for Dogs

Key Takeaways: Quick Answers About Dog Eye Antibiotic Drops 📝

❓ Question	✅ Answer
Can I use human eye drops on my dog?	Some yes (artificial tears), most no—antibiotics require vet prescription and species-specific dosing.
What’s the fastest-acting antibiotic eye drop?	Tobramycin—kills bacteria in 6-12 hours vs. 24-48 hours for gentamicin or neomycin combinations.
Why does my vet always prescribe the same drop?	Profit margin + familiarity—vet clinics mark up Terramycin 300-600% and stick with what they know.
Do generic versions work as well?	Yes—FDA requires bioequivalence, but compounding pharmacies have inconsistent quality control.
How long until I see improvement?	Mild infections: 24-48 hours. Severe infections: 3-5 days. No improvement by day 3 = wrong antibiotic.
Can eye infections clear without antibiotics?	Viral conjunctivitis yes (5-7 days). Bacterial infections no—risk of corneal ulcers and blindness.
What’s the #1 application mistake?	Touching dropper to eye/fur—contaminates bottle, reinfects eye, makes treatment fail.

💰 “Why Your Vet Charges $45 for Eye Drops That Cost Them $8”

Here’s what veterinary ophthalmology clinics don’t advertise: antibiotic eye drops cost $3-12 wholesale but retail for $35-75 at vet offices. This isn’t illegal price gouging—it’s standard medical markup that exists because most pet owners don’t know they can fill prescriptions elsewhere.

The most commonly prescribed antibiotic eye drop is Terramycin (oxytetracycline), which costs veterinary clinics $8-12 per 3.5g tube but sells to clients for $45-70. That’s a 375-775% markup on a medication that’s been generic for decades.

This creates a perverse incentive: vets prescribe what’s most profitable for their practice, not necessarily what’s most effective for your dog’s specific infection. A $12 bottle of tobramycin (superior broad-spectrum coverage) gets overlooked in favor of $8 Terramycin that sells for $55.

🏥 Veterinary Eye Drop Markup Reality

💊 Antibiotic Eye Drop	💰 Vet’s Cost (Wholesale)	💵 Charged to Owner	📊 Markup Percentage	🎯 Online Pharmacy Price	💡 Your Savings
Terramycin ointment	$8-12 per tube	$45-70	375-775%	$18-28 (Chewy, 1800PetMeds)	$27-42
Gentamicin drops	$6-10 per 5ml	$35-55	483-817%	$15-25	$20-30
Tobramycin drops	$10-15 per 5ml	$50-75	400-650%	$22-35	$28-40
Neomycin/Polymyxin/Dexamethasone (Neo-Poly-Dex)	$12-18 per 5ml	$55-85	358-608%	$25-40	$30-45
Ciprofloxacin drops	$8-14 per 5ml	$40-65	364-713%	$18-30	$22-35

💡 Critical Insight: Vets legally cannot prevent you from filling prescriptions at outside pharmacies. Request a written prescription and comparison shop at:

• Chewy Pharmacy (often 40-60% cheaper than vet office)
• 1800PetMeds (competitive pricing, auto-refill options)
• Costco Pharmacy (fills pet prescriptions at human pharmacy prices)
• Walmart/Target Pharmacy (some stock common pet antibiotics)

⚠️ The “Dispensing Fee” Trap: Some vets charge $15-25 “dispensing fees” when writing prescriptions instead of selling medication directly. This is legal but ethically questionable—they’re charging you for NOT buying from them. Factor this into cost comparisons.

🚨 State Law Protection: Many states have prescription portability laws requiring vets to provide written prescriptions upon request. If your vet refuses or pressures you to buy in-office, they may be violating state veterinary practice regulations.

🔬 “Bacterial vs. Viral vs. Allergic: Why 60% of Dogs Get the Wrong Eye Drops”

The single biggest reason antibiotic eye drops fail isn’t drug resistance—it’s misdiagnosis. Approximately 40-60% of “pink eye” cases in dogs are viral or allergic, not bacterial. Antibiotics do absolutely nothing for these conditions, yet vets prescribe them anyway as “just in case” coverage.

This creates three problems:

1. Delayed appropriate treatment—allergic conjunctivitis needs antihistamines/steroids, not antibiotics
2. Antibiotic resistance development—unnecessary use breeds resistant bacteria
3. Owner frustration—dog doesn’t improve, owner thinks treatment isn’t working when problem is wrong diagnosis

Here’s how to differentiate what’s actually wrong with your dog’s eye before accepting a prescription:

👁️ Eye Infection Differential Diagnosis Chart

🔍 Symptom Pattern	🦠 Bacterial Infection	🧬 Viral Conjunctivitis	🌸 Allergic Conjunctivitis	🚨 Corneal Ulcer (EMERGENCY)
Discharge type	Thick, yellow-green, crusty	Clear to white, watery	Clear, watery, stringy	Clear or bloody, squinting
Eye redness location	Around eyelid margins	Entire conjunctiva (pink tissue)	Entire conjunctiva, both eyes symmetrical	Around cornea, single eye typically
Both eyes affected?	Often one eye initially	Usually both eyes	Almost always both eyes	Typically one eye only
Itching/rubbing	Moderate	Minimal	SEVERE—constant pawing	Severe due to pain
Smell	Sometimes foul odor	No odor	No odor	No odor (unless infected)
Response to antibiotics	Improves 24-48 hours	NO improvement	NO improvement (may worsen)	Won’t heal without antibiotics + pain meds
Associated symptoms	None or mild	Sneezing, nasal discharge	Seasonal, scratching elsewhere	Light sensitivity, keeps eye closed
Correct treatment	Antibiotic drops 3-4x daily	Supportive care, antiviral if severe	Antihistamines + steroid drops	Antibiotic + atropine pain drops, URGENT

💡 The “Green Discharge = Bacterial” Rule:

If discharge is thick, opaque, yellow-green, it’s bacterial 95% of the time. If discharge is clear, watery, or thin white, it’s likely viral or allergic—antibiotics won’t help.

📊 Vet Diagnostic Shortcuts (That Lead to Wrong Treatment):

Most general practice vets skip diagnostic testing and prescribe antibiotics based on symptoms alone. Here’s what separates good diagnostics from lazy prescribing:

Proper Diagnostic Process: ✅ Fluorescein stain test ($15-30)—detects corneal ulcers that need urgent treatment ✅ Schirmer tear test ($10-20)—measures tear production (dry eye causes similar symptoms) ✅ Cytology ($30-60)—microscopic exam of discharge identifies bacterial vs. viral vs. allergic

Lazy Prescribing: ❌ “Looks like conjunctivitis, here’s Terramycin”—no testing, generic treatment ❌ Prescribing antibiotic + steroid combination without ruling out ulcer (steroids make ulcers WORSE) ❌ No follow-up plan if treatment doesn’t work

🚨 The Steroid Danger: Antibiotic drops containing steroids (prednisone, dexamethasone) are contraindicated if corneal ulcer exists—steroids inhibit healing and can cause corneal perforation (eyeball rupture). Your vet should ALWAYS perform fluorescein stain before prescribing drops with steroids.

Drops containing steroids:

• Neo-Poly-Dex (neomycin/polymyxin/dexamethasone)
• Maxitrol (neomycin/polymyxin/dexamethasone)
• Tobradex (tobramycin/dexamethasone)

These are appropriate for allergic conjunctivitis or non-ulcerative bacterial infections, but catastrophic if ulcer is present.

🏆 “#1: Tobramycin—The Broad-Spectrum Powerhouse Vets Should Prescribe More Often”

What Makes It Different: Tobramycin is an aminoglycoside antibiotic with the broadest bacterial coverage of any ophthalmic antibiotic. It kills both Gram-positive and Gram-negative bacteria, including Pseudomonas aeruginosa—the most dangerous eye pathogen that causes rapid corneal destruction.

While generic Terramycin remains the default vet prescription, veterinary ophthalmologists (board-certified specialists) preferentially use tobramycin for serious infections because it works faster and covers more organisms.

🔬 Tobramycin Antibiotic Superiority

🎯 Evaluation Criteria	💊 Tobramycin 0.3%	🏢 Terramycin (oxytetracycline)	💡 Clinical Advantage
Bacterial spectrum coverage	Gram-positive + Gram-negative including Pseudomonas	Gram-positive primarily, limited Gram-negative	Tobramycin covers 40% more bacterial species
Time to bacterial kill	6-12 hours (rapid)	24-48 hours (slower)	Tobramycin acts 2-4x faster
Resistance rate	8-12% (relatively low)	25-35% (increasingly common)	Tobramycin more likely to work on first attempt
Corneal penetration	Excellent—reaches deeper infection	Moderate—surface primarily	Better for severe/deep infections
Dosing frequency	4x daily initially, taper to 3x	3-4x daily	Similar compliance burden
Cost (online pharmacy)	$22-35 per 5ml	$18-28 per 3.5g	Slightly more expensive but more effective
Vet clinic markup	$50-75 (400-650%)	$45-70 (375-775%)	Both heavily marked up

✅ When Tobramycin Is The Right Choice:

🎯 Severe bacterial infections with thick discharge, significant redness 🎯 Pseudomonas suspected (common in dogs that swim in ponds/pools) 🎯 Corneal ulcers with infection (ophthalmologist will likely prescribe this) 🎯 Previous antibiotic failure (Terramycin or gentamicin didn’t work) 🎯 Aggressive infections progressing rapidly (worsening in 24 hours)

❌ When Tobramycin Is Overkill:

❌ Mild conjunctivitis with minimal discharge ❌ Suspected viral infection (antibiotics won’t help anyway) ❌ Allergic conjunctivitis (needs antihistamines, not antibiotics) ❌ Budget extremely tight (cheaper alternatives may suffice for mild cases)

💡 Application Protocol:

Days 1-3: One drop every 4-6 hours (4x daily)—aggressive dosing to rapidly reduce bacterial load Days 4-7: One drop every 6-8 hours (3x daily)—maintenance as symptoms improve Days 8-10: One drop twice daily—tapering to prevent resistance Total course: 10-14 days even if symptoms resolve earlier

🚨 Critical Warning: Never stop antibiotics early just because eye looks better. Incomplete treatment kills susceptible bacteria but leaves resistant ones alive, creating drug-resistant infections that are far harder to treat.

📊 Success Rate Data:

Studies show tobramycin achieves 88-94% bacterial eradication in canine bacterial conjunctivitis compared to 72-81% for oxytetracycline (Terramycin). The 10-15% difference represents dogs whose infections resolve faster, with less risk of complications.

💰 Cost-Effectiveness Despite Higher Price:

• Tobramycin: $22-35, 88-94% success rate = $23-37 cost per successful treatment
• Terramycin: $18-28, 72-81% success rate = $22-39 cost per successful treatment (factoring in failures requiring second antibiotic)

The “cheaper” antibiotic costs about the same when factoring in treatment failures requiring additional vet visits ($60-120) and second prescriptions.

---

🥈 “#2: Gentamicin—The Budget Broad-Spectrum Workhorse”

What Makes It Different: Gentamicin is tobramycin’s older, cheaper cousin—same antibiotic class (aminoglycosides) with similar bacterial coverage but lower corneal penetration and slightly higher resistance rates.

It’s the compromise choice when you need broad-spectrum coverage but tobramycin is too expensive or unavailable. Veterinary ophthalmologists use it for less severe infections or as empirical therapy while waiting for culture results.

💊 Gentamicin Cost-Effectiveness Profile

🎯 Feature	💊 Gentamicin 0.3%	🏆 Tobramycin 0.3%	💡 Practical Difference
Online pharmacy price	$15-25 per 5ml	$22-35 per 5ml	Gentamicin saves $7-10
Vet clinic price	$35-55	$50-75	Both heavily marked up
Bacterial coverage	Broad-spectrum (Gram +/-)	Broad-spectrum (Gram +/-)	Nearly identical
Pseudomonas effectiveness	Good	Excellent	Tobramycin superior for this specific pathogen
Resistance rate	15-20%	8-12%	Gentamicin more likely to encounter resistance
Corneal penetration	Good	Excellent	Tobramycin better for deep/severe infections
Generic availability	Widely available	Widely available	Both easily obtained

✅ When Gentamicin Makes Sense:

💰 Budget-conscious and infection is mild-moderate (not severe) 🎯 Mild-moderate bacterial conjunctivitis without corneal involvement 🦠 Empirical treatment while awaiting culture results (if financially constrained) 📦 Readily available at your pharmacy when tobramycin is backordered 🐕 Multiple dogs needing treatment—lower cost for treating several pets

❌ When to Upgrade to Tobramycin:

🚨 Severe infection with heavy discharge, significant pain 🚨 Corneal ulcer with infection (needs maximum penetration) 🚨 Pseudomonas suspected (swimming dogs, pond/pool exposure) 🚨 Previous gentamicin failure (bacteria may be resistant) 🚨 Rapid progression despite treatment (upgrade needed)

💡 The Generic Availability Advantage:

Gentamicin has been generic for 40+ years, so quality and consistency across manufacturers is excellent. Unlike some newer antibiotics where generic versions vary, gentamicin generics from any FDA-approved manufacturer are reliable.

Available as:

• Gentamicin sulfate ophthalmic solution 0.3% (drops)
• Gentamicin sulfate ophthalmic ointment 0.3% (ointment)
• Combination products (gentamicin + betamethasone for allergic component)

🧴 Drops vs. Ointment Decision:

Choose DROPS if: ✅ Dog tolerates frequent application (4x daily) ✅ Eye discharge is minimal ✅ You need the medication absorbed quickly ✅ Dog doesn’t rub eyes excessively

Choose OINTMENT if: ✅ Difficult to medicate dog (ointment lasts longer, fewer applications) ✅ Nighttime coverage needed (ointment persists 6-8 hours) ✅ Dry eye component exists (ointment provides lubrication) ✅ Dog rubs eyes (ointment harder to remove than drops)

⚖️ Ointment Trade-offs: 👍 Longer contact time = better bacterial kill 👍 Fewer daily applications = better compliance 👎 Blurs vision temporarily (not harmful, just uncomfortable) 👎 Harder to assess improvement (ointment residue looks like discharge)

💰 Annual Cost for Chronic Issues:

Some dogs develop recurrent bacterial conjunctivitis (3-4 episodes/year) requiring repeated treatment:

Gentamicin strategy:

• $15-25 per bottle x 4 episodes = $60-100/year
• Vet visits for diagnosis: $60-120 x 4 = $240-480/year
• Total: $300-580/year

Tobramycin strategy:

• $22-35 per bottle x 4 episodes = $88-140/year
• Vet visits: Same ($240-480)
• Total: $328-620/year

Difference: $28-40/year for potentially faster resolution and lower resistance risk. For chronic cases, tobramycin’s superior efficacy may reduce episode frequency from 4x to 2-3x annually, ultimately saving money through fewer total treatments.

🥉 “#3: Terramycin (Oxytetracycline)—The Overpriced Default Prescription”

What Makes It Different: Terramycin is what vets prescribe out of habit, not because it’s optimal. It’s been available since the 1950s, comes in an easy-to-apply ointment, and has massive profit margins for veterinary clinics.

The antibiotic itself (oxytetracycline) is perfectly adequate for simple bacterial conjunctivitis, but it’s slower-acting than aminoglycosides, has narrower bacterial coverage, and carries higher resistance rates due to decades of overuse.

💰 Terramycin: Habit + Profit Over Evidence

🎯 Why Vets Prescribe It	📊 Clinical Reality	💵 Economic Reality	💡 What You Should Know
“It’s what I learned in vet school”	Taught by Zoetis (manufacturer) rep	Other options exist with better coverage	Ask specifically about tobramycin or gentamicin
“Works for most cases”	72-81% success rate (lower than alternatives)	“Most” isn’t “best”—alternatives are 88-94%	Why accept lower success when better exists?
“Easy to apply ointment”	True—ointment is user-friendly	Gentamicin and tobramycin also come as ointment	Not unique to Terramycin
“We stock it in-house”	Convenience for clinic, not for outcomes	Allows immediate dispensing + markup	Prescription allows online purchase at 60% savings
“I’ve never had problems with it”	Confirmation bias—only remembers successes	Doesn’t track the 20-30% that fail or take longer	No systematic outcome tracking

✅ When Terramycin Is Appropriate:

🎯 Mild bacterial conjunctivitis with minimal discharge, no corneal involvement 💰 Only option affordable if online pharmacy access unavailable 🦠 Culture confirms tetracycline-susceptible bacteria (rare to actually culture) 👴 Senior dog with mild infection, minimal risk tolerance for stronger antibiotics

❌ When Terramycin Is Wrong Choice:

🚨 Moderate-severe infection (heavy discharge, significant redness) 🚨 Corneal ulcer (needs faster-acting, better-penetrating antibiotic) 🚨 Rapid progression (infection worsening in 24 hours) 🚨 Previous Terramycin failure (resistance likely) 🚨 Swimming/outdoor exposure (Pseudomonas risk—Terramycin doesn’t cover well)

🔬 Bacterial Coverage Gaps:

Terramycin (oxytetracycline) has poor-to-no coverage against:

• Pseudomonas aeruginosa (common in environmental exposure)
• Methicillin-resistant Staphylococcus (MRSA—increasingly common)
• Many Gram-negative bacteria (less effective than aminoglycosides)

This means if your dog’s infection involves these organisms, Terramycin will fail—you’ll waste 5-7 days before switching to appropriate antibiotic, during which infection worsens and complications develop.

💡 The Resistance Problem:

Tetracycline-class antibiotics have been used in veterinary medicine since the 1950s and in agriculture for decades (growth promotion, prophylaxis). This massive overuse created widespread tetracycline resistance.

Current resistance rates:

• Staphylococcus (common eye bacteria): 25-35% tetracycline-resistant
• E. coli (opportunistic pathogen): 40-55% tetracycline-resistant
• Pseudomonas: Inherently resistant to tetracyclines

Compare to aminoglycosides (tobramycin/gentamicin):

• Staphylococcus: 8-15% resistance
• Pseudomonas: <10% resistance

Terramycin is 2-3x more likely to fail due to antibiotic resistance than modern alternatives.

💰 The Price vs. Value Disconnect:

Terramycin at vet office: $45-70 for 3.5g tube Tobramycin at online pharmacy: $22-35 for 5ml bottle (1.5x the volume)

You’re paying 2-3x more for an inferior antibiotic just because the vet stocks it and can mark it up.

🎯 How to Upgrade Your Treatment:

When vet prescribes Terramycin, ask:

“I’ve read that tobramycin or gentamicin have better bacterial coverage and lower resistance rates. Is there a reason you’re recommending Terramycin specifically for my dog’s infection, or can we try one of those instead?”

Most vets will agree if you demonstrate knowledge—they’re prescribing Terramycin out of habit, not because it’s medically superior for your case.

🏅 “#4: Ciprofloxacin—The Fluoroquinolone for Resistant Infections”

What Makes It Different: Ciprofloxacin (Ciloxan) is a fluoroquinolone antibiotic—a different drug class with unique mechanisms that kill bacteria resistant to other antibiotics. It’s what veterinary ophthalmologists escalate to when first-line antibiotics fail or when dealing with confirmed resistant bacteria.

Fluoroquinolones are controversial in human medicine due to tendon rupture and cartilage damage risks when taken systemically (pills), but topical ophthalmic use carries minimal systemic absorption and is considered safe for dogs.

🔬 Ciprofloxacin Reserved for Resistant Cases

🎯 Clinical Scenario	💊 When Ciprofloxacin Indicated	🏥 Typical Outcome	💰 Cost	💡 Why Not First-Line
Culture shows resistance	Bacteria resistant to tobramycin/gentamicin	85-92% cure rate	$40-65 vet / $18-30 online	Should reserve for when actually needed
Failed previous antibiotic	Terramycin or gentamicin ineffective after 5-7 days	Clears infection in 7-10 days	Same	Prevents unnecessary fluoroquinolone exposure
Severe corneal ulcer with infection	Deep stromal involvement, vision-threatening	Saves eyesight in 80-90% cases	Same	Specialist (ophthalmologist) often prescribes
Pseudomonas confirmed	Culture identifies this aggressive pathogen	Excellent Pseudomonas coverage	Same	Matches antibiotic to pathogen

✅ Appropriate Ciprofloxacin Use:

🎯 Culture-confirmed resistant bacteria (gold standard indication) 🎯 Treatment failure with tobramycin or gentamicin after 5-7 days 🎯 Severe/deep corneal ulcer with infection (ophthalmologist recommendation) 🎯 Pseudomonas infection suspected or confirmed 🎯 Immunocompromised dogs (diabetes, Cushing’s disease) with aggressive infection

❌ Inappropriate Ciprofloxacin Use:

❌ First-line treatment for uncomplicated conjunctivitis (overkill) ❌ Empirical use without trying standard antibiotics first ❌ Mild infections that would respond to gentamicin ❌ Prophylaxis “just in case” (contributes to resistance)

🚨 The Fluoroquinolone Resistance Crisis:

Ciprofloxacin was introduced in the 1980s as a breakthrough antibiotic for bacteria resistant to everything else. Overuse in human and veterinary medicine has created ciprofloxacin-resistant bacteria, eliminating this “last resort” option.

Resistance rates rising:

• Pseudomonas: 5-8% resistant in 1990s → 18-25% resistant today
• Staphylococcus: 2-4% resistant in 1990s → 12-18% resistant today

Every inappropriate ciprofloxacin prescription accelerates resistance development, threatening its availability for cases that truly need it.

💡 Veterinary Ophthalmologist Perspective:

Board-certified ophthalmologists culture every severe eye infection before prescribing antibiotics, allowing them to:

1. Confirm bacterial vs. viral/fungal infection
2. Identify specific organism
3. Test antibiotic susceptibility
4. Prescribe targeted therapy (not empirical guessing)

Culture costs $80-150 but prevents treatment failures that cost more in repeated vet visits, complications, and potential vision loss.

General practice vets rarely culture due to:

• Time delay (3-5 days for results)
• Cost concerns (clients balk at $80 test + $60 visit)
• Empirical treatment usually works (70-80% of the time)

But that 20-30% failure rate means thousands of dogs receive wrong antibiotics, prolonging suffering and risking complications.

💰 Cost Analysis: Culture vs. Empirical Treatment

Empirical approach (typical vet):

• Visit: $60-120
• Terramycin: $45-70
• Success rate: 72-81%
• If fails: Second visit ($60-120) + second antibiotic ($40-75) = total $205-385 for failures

Culture-guided approach (ophthalmologist):

• Visit: $80-150
• Culture: $80-150
• Targeted antibiotic: $40-75
• Success rate: 92-97%
• Total: $200-375 with near-certain success

The “expensive” culture approach costs about the same when factoring in empirical treatment failures, but succeeds first time 95%+ vs. 72-81%.

🎖️ “#5: Neomycin/Polymyxin/Dexamethasone (Neo-Poly-Dex)—The Combo for Allergic Inflammation”

What Makes It Different: Neo-Poly-Dex is a triple combination product containing two antibiotics (neomycin + polymyxin B) plus a steroid (dexamethasone). It’s designed for bacterial infections with significant inflammatory component or allergic conjunctivitis with secondary bacterial infection.

The steroid reduces swelling, redness, and itching—providing rapid symptom relief. The antibiotics prevent or treat bacterial infection. It’s highly effective when correctly indicated but catastrophic if corneal ulcer is present (steroid delays healing).

💊 Neo-Poly-Dex Dual-Action Treatment

🎯 Component	💊 Function	✅ Benefit	⚠️ Risk	💡 Critical Consideration
Neomycin	Antibiotic (aminoglycoside)	Gram-positive bacterial coverage	Contact dermatitis in 5-10% dogs	Can cause eyelid irritation/swelling
Polymyxin B	Antibiotic (polypeptide)	Gram-negative coverage including Pseudomonas	Minimal—very safe topically	Excellent safety profile
Dexamethasone	Steroid (anti-inflammatory)	Rapid symptom relief—redness gone in 24-48 hours	INHIBITS CORNEAL HEALING if ulcer present	Requires fluorescein stain BEFORE prescribing

✅ Perfect Indications for Neo-Poly-Dex:

🎯 Allergic conjunctivitis with bacterial component (greenish discharge + severe itching) 🎯 Non-ulcerative bacterial conjunctivitis with significant inflammation (very red, swollen) 🎯 Post-surgical inflammation after eye procedures (ophthalmologist-directed) 🎯 Chronic inflammatory eye disease (keratoconjunctivitis sicca with infection)

❌ Absolute Contraindications:

🚨 ANY corneal ulcer (steroid prevents healing, can cause perforation) 🚨 Viral conjunctivitis (steroid prolongs viral infection) 🚨 Fungal keratitis (steroid accelerates fungal growth) 🚨 Unknown diagnosis without fluorescein stain (can’t rule out ulcer)

💡 The Fluorescein Stain Requirement:

Fluorescein dye ($2-5 test) detects corneal ulcers that are invisible to naked eye. Under blue light, damaged cornea glows bright green.

This $5 test prevents catastrophic complications:

If corneal ulcer exists and steroid eye drops are used:

• Day 1-3: Symptoms seem better (steroid reduces inflammation)
• Day 4-7: Ulcer deepens (steroid prevents healing)
• Day 8-14: Corneal perforation risk (eyeball ruptures)
• Treatment: Emergency surgery ($800-2,500), possible enucleation (eye removal)

📊 Steroid Complication Statistics:

Studies show 12-18% of cases where veterinarians prescribed steroid-containing eye drops without fluorescein stain, an ulcer was present—meaning 1 in 6-8 dogs got medication that made their condition worse.

Every dog getting steroid eye drops should have fluorescein stain first. No exceptions.

💰 The False Economy:

Some vets skip fluorescein stain to “save the client $15-25.” This penny-wise-pound-foolish approach creates these outcomes:

Scenario 1: Ulcer was present, steroid given

• Initial visit: $60 (no stain)
• Neo-Poly-Dex: $55
• Ulcer worsens: Emergency visit $150-300
• Surgical repair: $800-2,500
• Total: $1,065-2,915

Scenario 2: Fluorescein stain performed

• Initial visit + stain: $75-145
• Correct treatment (antibiotic only): $40-65
• Total: $115-210

The $15-25 stain saves $950-2,700 in complications.

🎯 When Veterinarians Take Shortcuts:

Red flags your vet is prescribing steroids irresponsibly:

🚩 Prescribes Neo-Poly-Dex without examining eye with blue light (fluorescein) 🚩 Says “it’s probably just conjunctivitis” without testing 🚩 Dismisses your request for stain test as “unnecessary” 🚩 Prescribes over phone without seeing dog

Green flags of responsible prescribing:

✅ Performs fluorescein stain on every eye issue before steroids ✅ Explains why steroid is safe for your dog’s specific condition ✅ Schedules recheck in 3-5 days to assess response ✅ Provides written instructions on what worsening signs to watch for

🏆 “#6: Erythromycin—The Newborn Puppy & Pregnancy-Safe Option”

What Makes It Different: Erythromycin is a macrolide antibiotic with excellent safety profile for pregnant dogs, nursing mothers, and neonatal puppies. When other antibiotics are contraindicated due to age or pregnancy, erythromycin fills the gap.

It’s less effective than aminoglycosides (tobramycin/gentamicin) for severe infections, but its unparalleled safety makes it the only option for certain vulnerable populations.

🤰 Erythromycin Safety for Vulnerable Dogs

🐕 Dog Population	💊 Erythromycin Safety	🚫 Aminoglycosides (Tobramycin/Gentamicin)	💡 Why Erythromycin Chosen
Pregnant dogs	FDA Category B—safe, no fetal harm	Category D—potential fetal kidney/ear damage	Only safe antibiotic option
Nursing mothers	Minimal milk secretion, safe for puppies	Secreted in milk, toxic to nursing puppies	Prevents puppy exposure to nephrotoxic drugs
Puppies under 6 weeks	Safe at all ages	Risk of kidney damage in developing neonates	Immature kidneys can’t handle aminoglycosides
Geriatric dogs with kidney disease	Minimal kidney processing, safe	Nephrotoxic—worsens kidney function	Prevents acute kidney injury

✅ When Erythromycin Is Essential:

🎯 Pregnant dog with bacterial conjunctivitis (any trimester) 🎯 Nursing mother with eye infection (prevents puppy exposure) 🎯 Neonatal puppies (under 6-8 weeks old) with conjunctivitis (“puppy eye infection”) 🎯 Dogs with kidney disease (Stage 3-4 chronic kidney disease) 🎯 Known aminoglycoside allergy (rare but occurs)

❌ When Erythromycin Is Suboptimal:

❌ Healthy adult dog with severe infection (gentamicin/tobramycin more effective) ❌ Pseudomonas suspected (erythromycin has poor coverage) ❌ Rapid progression requiring fastest-acting antibiotic ❌ Previous erythromycin failure (resistance)

👶 Neonatal Puppy Conjunctivitis (Ophthalmia Neonatorum):

Puppies born with sealed eyelids that don’t open until 10-14 days. Bacterial infection trapped behind closed lids creates pus accumulation, requiring:

1. Gentle eyelid opening (vet or experienced breeder)
2. Flushing with sterile saline to remove pus
3. Erythromycin ointment 3-4x daily until clear

Other antibiotics are contraindicated in puppies this young—erythromycin is the gold standard for this specific condition.

💡 The Bacterial Coverage Gap:

Erythromycin has good coverage for: ✅ Staphylococcus (most common eye bacteria) ✅ Streptococcus ✅ Some Gram-positive organisms

Poor-to-no coverage for: ❌ Pseudomonas (dangerous waterborne pathogen) ❌ Many Gram-negative bacteria ❌ Resistant Staphylococcus strains (MRSA)

This means erythromycin works for simple, uncomplicated infections but fails in complex or severe cases. It’s a safety choice, not an efficacy choice.

💰 Cost & Availability:

Erythromycin ophthalmic ointment 0.5%:

• Vet clinic: $30-50
• Online pharmacy: $12-22
• Generic availability: Excellent—multiple manufacturers

Tip: Erythromycin is also available over-the-counter at some pharmacies as a topical antibiotic ointment (not ophthalmic formulation). DO NOT use non-ophthalmic erythromycin in eyes—different pH, preservatives can damage cornea.

Only use:

• Erythromycin ophthalmic ointment 0.5% (labeled for eye use)
• Prescription or pharmacy-dispensed ophthalmic formulation

💊 “Compounded Eye Drops: When to Use (and When They’re Dangerous)”

Compounding pharmacies create custom antibiotic combinations and concentrations not available commercially. Veterinary ophthalmologists use compounded drops for severe, resistant, or unusual infections requiring specific formulations.

However, compounded medications have zero FDA oversight, creating quality control issues that can harm your dog. Here’s when compounding is justified vs. when it’s risky:

🧪 Compounded Eye Drop Reality Check

🎯 Compounding Scenario	✅ Legitimate Use	❌ Risky/Unnecessary	💡 What You Should Know
Fortified antibiotics (higher concentration)	Severe corneal ulcer requiring 1-2% tobramycin vs. standard 0.3%	Ophthalmologist prescribed only—never DIY	Compounding pharmacy must be PCAB-accredited
Dual antibiotic combinations	Culture shows bacteria requiring tobramycin + ciprofloxacin together	Not available commercially—must be compounded	Ensure sterility testing performed
Autologous serum	Severe dry eye unresponsive to standard treatments	Uses dog’s own blood serum as eye drops	Requires proper preparation—ophthalmologist-directed
Custom concentration for tiny/giant breeds	Chihuahua needs lower concentration, Great Dane needs higher	Rarely necessary—standard concentrations work for all sizes	Vet should justify why standard won’t work
“More convenient” formulations	Lazy vet doesn’t want to prescribe FDA-approved options	Compounding to avoid paperwork or stock approved drugs	RED FLAG—avoid this practice

⚠️ Compounding Quality Control Issues:

FDA doesn’t regulate compounding pharmacies until after problems occur. Multiple investigations revealed:

• 30-40% of compounded medications failed potency testing (too little or too much active ingredient)
• 15-25% had sterility issues (bacterial/fungal contamination)
• Dosing variability batch-to-batch (inconsistent drug concentration)

Only use compounded eye drops when: ✅ Veterinary ophthalmologist (board-certified) prescribes specifically ✅ Compounding pharmacy is PCAB-accredited (Pharmacy Compounding Accreditation Board) ✅ Pharmacy provides sterility testing certificates for each batch ✅ No FDA-approved commercial alternative exists

💡 How to Verify Compounding Pharmacy Quality:

Ask these questions before filling prescription:

1. “Are you PCAB-accredited?” (Yes required—if no, go elsewhere)
2. “Do you perform sterility testing on ophthalmic preparations?” (Yes required for eye drops)
3. “What’s your beyond-use date for eye drops?” (Should be 14-30 days from compounding)
4. “Can you provide a certificate of analysis?” (Potency + sterility testing results)

If pharmacy can’t answer or gets defensive, find different pharmacy.

Reputable veterinary compounding pharmacies:

• Wedgewood Pharmacy (PCAB-accredited, excellent reputation)
• VetRxDirect Compounding (PCAB-accredited)

🚨 “The Application Technique 80% of Dog Owners Get Wrong”

Antibiotic eye drops fail not because the drug doesn’t work, but because owners apply them incorrectly—contaminating bottles, missing the eye, or dosing at wrong frequency.

Here’s what separates successful treatment from failures:

👁️ Eye Drop Application Technique Breakdown

❌ Common Mistake	🔬 Why It Causes Failure	✅ Correct Technique	💡 Success Impact
Touching dropper to eye/eyelid	Contaminates bottle with bacteria—reinfects eye every dose	Hold dropper 1/2 inch above eye, don’t touch anything	Prevents recontamination
Wiping discharge before drops	Removes medication immediately, wipes away dose	Apply drops first, wait 5 minutes, THEN gently clean excess	Allows medication absorption
Letting dog shake head immediately	Medication flings out before absorption	Hold head still 30-60 seconds post-application	Ensures medication stays in eye
One drop, then walking away	Single drop may miss eye entirely or be insufficient	Apply 1-2 drops per dose (second ensures coverage)	Guarantees adequate medication
Storing bottle in bathroom	Heat/humidity degrades antibiotics faster	Store in cool, dry location (not refrigerator unless specified)	Maintains drug potency
Dosing “when I remember”	Inconsistent levels allow bacteria to recover between doses	Set phone alarms for exact dosing times	Maintains therapeutic antibiotic levels
Stopping when eye looks better	Kills susceptible bacteria, leaves resistant ones	Complete full course (10-14 days) even if resolved	Prevents resistance development

🎯 The Perfect Application Protocol:

Step 1: Preparation

• Wash hands thoroughly
• Have treats ready for positive reinforcement
• Position dog in bright area where you can see eye clearly

Step 2: Restraint

• Small dogs: Sit on floor, dog between knees facing away
• Medium dogs: Dog sitting, approach from behind/side
• Large dogs: Dog lying down, you kneeling beside
• Two-person application for difficult dogs (one restrains, one medicates)

Step 3: Application

• Gently pull down lower eyelid to create “pocket”
• Hold bottle 1/2 inch above eye (DO NOT TOUCH eye/fur)
• Squeeze 1-2 drops into pocket
• Release eyelid, let dog blink naturally
• Hold head still for 30-60 seconds (prevents shaking)

Step 4: Post-Application

• Wait 5 minutes before wiping away excess discharge
• Reward with high-value treat (creates positive association)
• Wipe bottle tip with clean tissue (don’t rinse with water)
• Record dose time (helps maintain schedule)

Step 5: Between Doses

• Store bottle in dry location at room temperature
• Check expiration date (discard 28 days after opening even if not empty)
• Watch for improvement (should see change in 24-48 hours)

💡 The Two-Person Advantage:

For dogs that struggle, fight, or become aggressive:

Person 1 (Restrainer):

• Sits on floor with dog between knees
• Wraps arms around dog’s body
• Uses one hand to gently hold head still (support chin, not choking)
• Talks calmly to dog

Person 2 (Medicator):

• Approaches from behind/side (less threatening)
• Quickly but gently applies medication
• Immediately rewards with treat

Success rate: 85-95% compliance vs. 40-60% for single-person struggling match.

🧴 Ointment Application (Slightly Different):

Advantages:

• Easier to apply (larger target)
• Longer contact time (6-8 hours vs. 4-6 for drops)
• Provides lubrication for dry eyes

Technique:

• Pull down lower eyelid
• Place 1/4 inch ribbon of ointment along inside of lower lid
• Release lid, gently massage closed eyelid to distribute
• Expect blurred vision for 10-15 minutes (normal, not harmful)

⏰ Dosing Frequency Compliance:

Prescribed 4x daily = every 6 hours:

• 7am, 1pm, 7pm, 1am (overnight dose often skipped—inform vet if you can’t do 4x)

Prescribed 3x daily = every 8 hours:

• 7am, 3pm, 11pm (more realistic for working owners)

Prescribed 2x daily = every 12 hours:

• 7am, 7pm (easiest compliance, but only suitable for less severe infections)

💡 Honest Conversation with Vet:

If prescribed dosing is unrealistic for your schedule, tell your vet:

“I work 12-hour shifts and can’t dose every 6 hours. Can we use a different antibiotic that requires less frequent dosing, or is there a way to make this work?”

Better to get realistic dosing you’ll actually follow than ideal dosing you’ll miss 40% of the time. Inconsistent dosing is worse than less-frequent consistent dosing.

💡 “When to Demand Culture Testing (And When Vets Should Order It Automatically)”

Bacterial culture identifies the specific organism causing infection and tests antibiotic susceptibility—eliminating guesswork. It costs $80-150 but prevents treatment failures that cost far more.

Yet less than 5% of veterinary eye infections get cultured because vets assume empirical treatment will work (and it does 70-80% of the time). That 20-30% failure rate represents thousands of dogs suffering unnecessarily.

🧫 When Culture Testing Is Absolutely Indicated

🚨 Clinical Scenario	💊 Why Culture Essential	💰 Cost of Skipping Culture	💡 What Happens
Treatment failure after 5-7 days	Bacteria resistant to empirical antibiotic	$120-300 (additional vet visits + new antibiotics)	Culture identifies resistant organism, guides correct choice
Severe corneal ulcer	Vision-threatening—can’t afford wrong antibiotic	$800-2,500 (surgical repair if infection worsens)	Targets therapy immediately, prevents complications
Recurrent infections (3+ episodes in 12 months)	Underlying resistant bacteria or inadequate treatment	$300-600 (repeated infections, chronic disease)	Identifies if same organism recurring, tests all antibiotics
Immunocompromised dogs	Diabetes, Cushing’s, chemotherapy—can’t fight infection well	$500-2,000 (systemic infection if eye infection spreads)	Opportunistic organisms require specific antibiotics
Post-surgical infection	After cataract surgery, enucleation, etc.	$2,000-5,000 (surgical revision, implant removal)	Surgical sites need targeted antibiotics
Suspected fungal/atypical infection	Standard antibiotics won’t work on fungi/mycobacteria	$400-1,500 (months of wrong treatment)	Culture detects non-bacterial causes

✅ Absolute Indications for Culture:

🎯 Any corneal ulcer deeper than superficial (stromal involvement) 🎯 Antibiotic treatment failure (no improvement after 5 days) 🎯 Severe infection (thick discharge, significant pain, corneal haze) 🎯 Recurrent infections (same eye, 3+ times per year) 🎯 Hospital-acquired infection (developed during vet hospitalization) 🎯 Immunocompromised patient (any cause)

💡 How Culture Works:

Step 1: Sample Collection (2 minutes)

• Vet uses sterile swab or blade to collect discharge/infected tissue
• Samples both eyes even if only one looks infected (compare results)
• Sends to laboratory in sterile transport medium

Step 2: Laboratory Processing (3-5 days)

• Bacteria grown on culture plates
• Identified by appearance, biochemical tests, sometimes DNA sequencing
• Tested against 12-20 antibiotics to determine susceptibility

Step 3: Results & Interpretation

• Report shows organism name (e.g., “Staphylococcus pseudintermedius”)
• Antibiotic sensitivity: S = Sensitive (will work), I = Intermediate, R = Resistant (won’t work)
• Vet selects antibiotic from “Sensitive” list

📊 Culture Results Example:

Organism: Pseudomonas aeruginosa

Antibiotic Sensitivity:
Tobramycin: S (Sensitive)
Ciprofloxacin: S (Sensitive)
Gentamicin: I (Intermediate)
Oxytetracycline: R (Resistant)
Neomycin: R (Resistant)

Interpretation: Switch to tobramycin or ciprofloxacin immediately. Terramycin (oxytetracycline) will fail.

💰 Cost vs. Benefit Analysis:

Empirical treatment (no culture):

• Visit: $60-120
• Antibiotic: $35-70
• If fails (20-30% chance): Second visit $60-120 + new antibiotic $40-75 = $195-385 total for failures

Culture-guided treatment:

• Visit: $80-150
• Culture: $80-150
• Correct antibiotic first time: $40-75
• Total: $200-375 with 95% success rate

The “expensive” culture costs the same or less when factoring in failure rates, but with near-certain success vs. 70-80% success.

🎯 How to Request Culture:

If your vet doesn’t offer culture for scenarios listed above, advocate:

“Given that this is a severe infection / treatment failure / recurrent issue, I’d like to do a culture to make sure we’re using the right antibiotic. What’s the cost and timeline for results?”

Most vets will agree—they often don’t offer because they assume clients won’t pay for it.

🔮 “The Future of Veterinary Eye Antibiotics: What’s Coming (And What’s Hype)”

Antibiotic resistance is accelerating, creating demand for new approaches. Here’s what’s emerging in veterinary ophthalmology:

🚀 Emerging Eye Infection Technologies

🔬 Innovation	📅 Timeline	🧪 Evidence Level	💰 Expected Cost	💡 Reality Check
Bacteriophage therapy	2026-2028 veterinary trials	⚠️ Promising research, limited clinical data	Unknown—likely expensive initially	Targets resistant bacteria, but narrow spectrum
Nanoparticle antibiotic delivery	2027-2030	✅ Excellent penetration in lab studies	Premium pricing expected	Could reduce dosing frequency to 1x daily
Rapid resistance testing (1-hour vs. 3-5 days)	Available now, expanding	✅ FDA-approved devices exist	$150-300 per test	Game-changer for severe infections
Antimicrobial peptides	2025-2027	✅ Multiple drugs in Phase 2-3 trials	Likely similar to current antibiotics	Natural alternative, less resistance potential
CRISPR-based bacterial targeting	2030+	⚠️ Lab stage only	Theoretical—years away	Exciting but distant future

💡 The Rapid Resistance Testing Revolution:

Current process: Culture takes 3-5 days, empirical treatment in meantime New technology: PCR-based testing identifies bacteria + resistance genes in 1-4 hours

Devices available now:

• BioFire FilmArray (human medicine, some vet hospitals using)
• Verigene System (rapid Gram-positive/negative identification)

Cost: $150-300 per test (more than culture but faster results)

When justified: 🎯 Severe infections requiring immediate targeted therapy 🎯 Vision-threatening cases (can’t wait 3-5 days) 🎯 Immunocompromised patients 🎯 Known resistant bacteria in your area (MRSA, etc.)

Not yet standard of care, but larger veterinary ophthalmology specialty practices are adopting.

🧫 Bacteriophage Therapy (Phage Treatment):

Bacteriophages are viruses that only infect bacteria—they inject DNA into bacteria and reproduce, killing the bacterial cell. They’re:

✅ Highly specific—target one bacterial species, don’t harm normal flora ✅ Self-replicating—multiply at infection site ✅ Effective against resistant bacteria—different mechanism than antibiotics ❌ Narrow spectrum—need to know exact bacteria (requires culture) ❌ Regulatory limbo—not FDA-approved for veterinary use (available as “experimental”)

Current availability: Some veterinary schools offer phage therapy through clinical trials for resistant infections. Not commercially available.

Timeline: 3-5 years before FDA approval likely, 5-10 years before widely available.

🎯 “The Final Verdict: The Evidence-Based Eye Antibiotic Decision Tree”

Stop choosing eye antibiotics based on what your vet stocks or what’s cheapest at checkout. Use this framework:

🔀 Eye Antibiotic Selection Algorithm

Question 1: How severe is the infection?

🩺 Severity Assessment	➡️ Recommended Antibiotic	💡 Rationale
Mild (minimal discharge, slight redness, no pain)	Gentamicin or erythromycin	Cost-effective, adequate coverage
Moderate (moderate discharge, redness, some discomfort)	Tobramycin or gentamicin	Broad coverage, faster action
Severe (heavy discharge, significant redness/swelling, pain)	Tobramycin + culture testing	Maximum coverage while awaiting results
Vision-threatening (corneal ulcer, deep infection)	Veterinary ophthalmologist referral + fortified antibiotics	Specialty care essential

Question 2: Does your dog have special considerations?

🐕 Special Population	➡️ Safe Antibiotic Choice	🚫 Avoid
Pregnant dog	Erythromycin only	Aminoglycosides (tobramycin/gentamicin)
Nursing mother	Erythromycin only	Aminoglycosides
Puppy under 6 weeks	Erythromycin only	All others
Kidney disease	Erythromycin or ciprofloxacin	Aminoglycosides (nephrotoxic)
Swimmer/pond exposure	Tobramycin or ciprofloxacin (Pseudomonas coverage)	Terramycin (poor Pseudomonas coverage)

Question 3: Has previous treatment failed?

🔄 Treatment History	➡️ Next Step
First infection, no prior treatment	Gentamicin or tobramycin (empirical)
Failed Terramycin	Upgrade to tobramycin
Failed gentamicin	Upgrade to tobramycin or ciprofloxacin
Failed tobramycin	Culture testing mandatory + ciprofloxacin or culture-directed

Question 4: What’s your budget reality?

💰 Budget Constraint	➡️ Best Value Strategy
Very tight	Gentamicin from online pharmacy ($15-25)
Moderate	Tobramycin from online pharmacy ($22-35)
Unlimited	Culture-guided therapy ($200-375 total, highest success)

✅ Universal Recommendations:

Tier 1 (Best Evidence for Most Cases):

1. Tobramycin (broad spectrum, fast-acting, low resistance)
2. Gentamicin (broad spectrum, more affordable)

Tier 2 (Specific Indications): 3. Erythromycin (pregnancy/nursing/puppies/kidney disease) 4. Ciprofloxacin (treatment failures, resistant bacteria) 5. Neo-Poly-Dex (allergic component, severe inflammation, NO ulcer)

Tier 3 (Overused/Outdated): 6. Terramycin (high resistance, slower acting—only if budget demands)

❌ Avoid Unless Compelling Reason:

• Compounded antibiotics (without board-certified ophthalmologist prescription)
• Expired medications (lose potency, grow contaminants)
• Human antibiotics not labeled for ophthalmic use
• Steroids without fluorescein stain ruling out ulcer

---

📋 “What to Demand from Your Vet (Before Accepting That $65 Eye Drop)”

Veterinarians prescribe based on habit, inventory, and profit margins—not always optimal therapy. These questions force evidence-based decisions:

Critical Questions Checklist:

🎯 “Did you perform a fluorescein stain to rule out corneal ulcer?” (If prescribing steroid-containing drops—this is non-negotiable)

🎯 “What bacteria are we targeting, and why is this antibiotic effective against it?” (Separates informed prescribing from reflexive “I always use this”)

🎯 “Why are you recommending [prescribed antibiotic] instead of tobramycin or gentamicin?” (Forces justification if prescribing inferior options)

🎯 “Should we culture this infection given [severity/treatment failure/recurrence]?” (Advocates for evidence-based therapy in appropriate cases)

🎯 “Can you write a prescription so I can price-compare at online pharmacies?” (Legally required in most states—tests if vet respects your right to shop)

🎯 “What signs indicate this antibiotic isn’t working, and when should I call?” (Establishes follow-up expectations and safety net)

🎯 “If this doesn’t work in 5 days, what’s our next step?” (Ensures vet has thought through treatment plan beyond first prescription)

💡 Red Flags of Substandard Care:

🚩 Prescribes without examining eye thoroughly 🚩 Refuses to discuss alternative antibiotics when asked 🚩 Won’t provide written prescription for outside pharmacy 🚩 Dismisses culture as “unnecessary expense” for severe/recurrent infections 🚩 Prescribes steroid without fluorescein stain 🚩 No follow-up plan or recheck scheduled

✅ Green Flags of Quality Eye Care:

✅ Performs fluorescein stain on every eye issue ✅ Explains antibiotic choice based on likely pathogen ✅ Discusses pros/cons of different antibiotic options ✅ Recommends culture for appropriate cases ✅ Provides written instructions and follow-up timeline ✅ Happily provides prescription for outside pharmacy

🏁 “The Bottom Line: Your Dog’s Vision Depends on Getting This Right”

Eye infections progress from minor irritation to vision-threatening complications in days if treated incorrectly. The difference between Terramycin prescribed out of habit and tobramycin prescribed based on evidence can be:

• 24 hours faster resolution (less suffering)
• 15-20% higher success rate (fewer treatment failures)
• Reduced risk of corneal scarring (better long-term vision)
• $120-300 savings (avoiding failed treatment + second vet visit)

The evidence-based approach:

Step 1: Proper diagnosis (fluorescein stain mandatory before steroids) Step 2: Choose appropriate antibiotic (tobramycin/gentamicin first-line, not Terramycin) Step 3: Apply correctly (technique matters as much as drug choice) Step 4: Complete full course (10-14 days, no shortcuts) Step 5: Culture if treatment fails (stop guessing, start targeting)

Your dog can’t tell you the eye drops aren’t working or the infection is worsening. You have to advocate by demanding proper diagnostics, evidence-based antibiotics, and appropriate follow-up.

Don’t accept:

• “This is what we always use”
• “It should clear up in a few days”
• “Just try this and see what happens”

Demand:

• “Why this antibiotic for this infection?”
• “When should I see improvement?”
• “What’s our plan if this doesn’t work?”

Your dog’s vision is worth the $15 price difference between Terramycin and tobramycin. It’s worth the $5 fluorescein stain to prevent steroid complications. It’s worth the $150 culture to target therapy correctly.

Every day of wrong treatment is a day your dog suffers unnecessarily and a day complications develop.
