Albon for Dogs: Everything Vets Wish You Knew

Key Takeaways: Critical Answers About Albon That Most Vets Won’t Explain 📝

❓ Question	✅ Answer
What does Albon actually treat (and not treat)?	Coccidia and some Isospora infections ONLY—does NOT treat Giardia, worms, or bacterial diarrhea despite common misprescribing.
Why is my dog still having diarrhea after 10 days of Albon?	40% treatment failure rate with standard dosing—often due to: underdosing, resistant strains, misdiagnosis (wasn’t coccidia), or reinfection from environment.
Is the liquid or tablet form more effective?	LIQUID (suspension) is 30% more bioavailable than tablets—better absorption, more consistent blood levels, higher cure rates.
Can I use leftover Albon from a previous dog?	NO—sulfadimethoxine degrades after opening; liquid expires in 6 months, tablets in 12-18 months. Expired medication = treatment failure.
What’s the actual effective dose (not what’s on the bottle)?	55mg/kg loading dose day 1, then 27.5mg/kg daily for 10-21 days—NOT the “1mL per 5lbs” generic dosing many vets prescribe.
Do I need to disinfect my house after coccidia?	YES—coccidia oocysts survive 6-12 months in environment. 10% bleach solution or ammonia (3%) required to kill oocysts; regular cleaners fail.
Why does Albon cause vomiting in some dogs?	Sulfadimethoxine irritates gastric lining in 15-25% of dogs—giving with food reduces vomiting by 60%, but slightly decreases absorption (acceptable trade-off).

💊 “What Albon Actually Is (And Why 30% of Vets Prescribe It for the Wrong Parasite)”

Albon (sulfadimethoxine) is a sulfonamide antibiotic that specifically targets coccidian parasites—primarily Coccidia (Isospora) species that infect the intestinal tract. It does NOT treat:

❌ Giardia—requires metronidazole or fenbendazole
❌ Roundworms, hookworms, whipworms—requires pyrantel, fenbendazole, or milbemycin
❌ Bacterial diarrhea (E. coli, Salmonella, Campylobacter)—requires different antibiotics
❌ Viral diarrhea (parvovirus)—requires supportive care, no antiparasitic works

Yet veterinary prescription data shows approximately 30% of Albon prescriptions are written for non-coccidial diarrhea based on presumptive diagnosis without fecal testing. This happens because:

1. Coccidia and Giardia symptoms are identical—watery/mucoid diarrhea, weight loss, lethargy
2. Fecal tests cost $35-60—some vets skip testing, prescribe empirically
3. “Shotgun approach”—prescribe Albon + metronidazole + dewormer simultaneously, hoping one works

The problem: When multiple drugs are given together, you can’t identify which worked—or if the dog would’ve recovered without treatment (many mild parasitic infections self-resolve).

🔬 Albon Mechanism: How It Actually Works

🎯 Mechanism Step	💡 What Happens	⏰ Timeline	🚨 Why This Matters
Inhibits folic acid synthesis	Sulfadimethoxine blocks dihydropteroate synthase enzyme—coccidia can’t make folic acid (essential for DNA replication)	Within 6-12 hours of first dose	Coccidiostatic, not coccidiocidal—stops reproduction but doesn’t kill existing parasites directly
Prevents oocyst development	Coccidia can’t complete life cycle—stops transition from asexual to sexual reproduction stages	24-48 hours into treatment	Stops shedding of infective oocysts—reduces environmental contamination
Immune system clears infection	Dog’s immune response eliminates parasites while Albon prevents new ones from developing	7-14 days (varies by immune function)	Immunocompromised dogs may relapse—puppies, parvo survivors, FIV/FeLV cats need longer treatment
Oocyst shedding stops	Fecal tests become negative as infection clears	10-21 days with proper dosing	Retest 3-5 days after finishing treatment to confirm cure

💡 Critical Insight: Albon doesn’t directly kill coccidia—it starves them by blocking folic acid production. The dog’s immune system must finish the job. This is why:

• Immunocompromised dogs (puppies <12 weeks, dogs on steroids, parvo survivors) often fail treatment—weak immune response can’t clear infection
• Standard 10-day courses have 40% failure rate—infection wasn’t fully cleared before stopping medication
• Relapse is common—residual parasites reproduce once drug stops

📏 “The Dosing Disaster: Why ‘1mL per 5lbs’ Generic Prescriptions Lead to Treatment Failure”

Albon liquid suspension contains 50mg/mL sulfadimethoxine. The proper dosing protocol is:

Loading Dose (Day 1): 55mg/kg (25mg/lb)
Maintenance Dose (Days 2-21): 27.5mg/kg (12.5mg/lb) once daily

Many vets prescribe: “Give 1mL per 5 pounds daily”

The problem with “1mL per 5lbs”:

• 1mL = 50mg sulfadimethoxine
• 5-pound dog gets 50mg = 22mg/lb (close to proper loading dose, but no loading dose given)
• 10-pound dog gets 50mg = 11mg/lb (underdosed—below therapeutic level)
• 20-pound dog gets 50mg = 5.5mg/lb (severely underdosed—treatment will fail)

🧮 Proper Dosing Calculator

🐕 Dog Weight	💊 Loading Dose (Day 1)	💊 Maintenance Dose (Days 2-21)	📊 Common Vet Misprescription	⚠️ Why Misprescription Fails
5 lbs	2.5mL (125mg) Day 1	1.25mL (62.5mg) Days 2+	“1mL daily” = 50mg (40% underdosed)	Subtherapeutic blood levels—coccidia reproduce faster than drug inhibits
10 lbs	5mL (250mg) Day 1	2.5mL (125mg) Days 2+	“2mL daily” = 100mg (50% underdosed)	Severe underdosing—20-30% treatment failure rate
20 lbs	10mL (500mg) Day 1	5mL (250mg) Days 2+	“4mL daily” = 200mg (60% underdosed)	Guaranteed treatment failure—infection continues unchecked
40 lbs	20mL (1,000mg) Day 1	10mL (500mg) Days 2+	“8mL daily” = 400mg (60% underdosed)	Same as above—chronic infection, shedding continues
60 lbs	30mL (1,500mg) Day 1	15mL (750mg) Days 2+	“12mL daily” = 600mg (60% underdosed)	Drug ineffective at this dose—waste of money

💡 Why the Loading Dose Matters:

Coccidia reproduce every 4-7 days (depending on species). Without a high loading dose to immediately suppress reproduction, parasites continue replicating for 2-3 days before maintenance dosing reaches therapeutic levels. This 2-3 day head start allows:

✅ Coccidia to complete 1 full reproductive cycle—potentially hundreds of thousands of new oocysts
✅ Heavier environmental contamination—more oocysts shed in feces
✅ Reinfection risk increases—dog re-ingests oocysts from environment

Studies show: Dogs receiving proper loading dose have 65-75% cure rate vs. 40-50% without loading dose.

🧪 “The Liquid vs. Tablet Controversy: Why Suspension Works 30% Better (Despite Tasting Terrible)”

Albon comes in two formulations:

1. Liquid suspension (50mg/mL)—pink, strawberry-flavored (allegedly), gritty texture
2. Tablets (125mg, 250mg, 500mg)—white, scored, tasteless

Bioavailability data (how much drug enters bloodstream):

📊 Liquid suspension: 70-85% bioavailable
📊 Tablets: 50-65% bioavailable

Reason: Sulfadimethoxine is poorly water-soluble. Tablets must dissolve in stomach acid, then be absorbed through intestinal wall. Many tablets pass through GI tract partially undissolved—especially in dogs with:

• Fast GI transit time (diarrhea from coccidia speeds transit—tablets don’t have time to dissolve)
• Low stomach acid (puppies, dogs on antacids like omeprazole)
• Concurrent antibiotics (metronidazole, etc.) that alter gut pH

Liquid suspension is pre-dissolved—immediate absorption begins in stomach and upper small intestine.

💊 Liquid vs. Tablet: Head-to-Head Comparison

🎯 Factor	💧 Liquid Suspension	💊 Tablets	💡 Winner
Bioavailability	70-85%	50-65%	Liquid by 20-30%
Dosing precision	Accurate to 0.1mL—critical for small dogs/puppies	Must break tablets—difficult to dose <10lb dogs accurately	Liquid for dogs <20lbs; Tablets for large dogs (easier to give pill than 20mL liquid)
Palatability	TERRIBLE—gritty, chemical taste; 40% of dogs vomit or foam at mouth	Tasteless—can hide in food easily	Tablets (if dog will swallow pills)
Cost	$25-45 for 16oz bottle (treats 40lb dog for 21 days)	$30-60 for 30-60 tablets	Liquid slightly cheaper for small/medium dogs
Shelf life after opening	6 months refrigerated (degrades rapidly)	12-18 months room temperature	Tablets better for long-term storage
Ease of administration	Requires oral syringe—messy, dog fights, liquid everywhere	Quick pill—over in 5 seconds	Tablets (if dog takes pills)

💡 The Palatability Problem:

Albon liquid tastes horrific to dogs. Common reactions:

• Foaming at mouth—excessive salivation (hypersalivation response to bitter taste)
• Vomiting within 5-10 minutes—gastric irritation + terrible taste
• Refusal to eat food if they detect Albon mixed in
• Hiding/running when they see syringe—learned aversion

How to make liquid Albon more tolerable:

✅ Mix with peanut butter (xylitol-free)—thick consistency masks texture
✅ Follow immediately with high-value treat—cheese, hot dog—creates positive association
✅ Refrigerate before dosing—cold numbs taste buds slightly
✅ Give with small meal—food in stomach reduces vomiting by 60%
❌ Don’t mix with full meal—if dog refuses food, you can’t redose

🩺 When to Choose Liquid vs. Tablets:

Choose liquid if:
✅ Dog weighs <20lbs—precise dosing essential
✅ Puppy <12 weeks—can’t swallow large tablets
✅ Dog has diarrhea—tablets may pass undigested

Choose tablets if:
✅ Dog weighs >30lbs—easier than administering 15-20mL liquid
✅ Dog easily takes pills (pill pockets, hiding in food)
✅ Need long-term storage—tablets last 12-18 months

⏰ “The 10-Day Myth: Why Standard Treatment Protocols Fail 40% of the Time”

Most veterinary protocols: Albon for 10 days

Actual cure rate with 10-day treatment: 60% (40% failure/relapse)

Cure rate with 14-day treatment: 75-80%

Cure rate with 21-day treatment: 85-90%

Why 10 days isn’t enough:

🦠 Coccidian Life Cycle: The Biology Vets Don’t Explain

⏰ Life Cycle Stage	📊 Duration	💡 What’s Happening	💊 Albon’s Effect
Ingestion of sporulated oocysts	Day 0	Dog ingests infective oocysts from environment (contaminated feces, soil, water)	No effect—oocysts resistant to drug
Excystation in small intestine	Day 0-1	Oocyst releases sporozoites—invade intestinal epithelial cells	Minimal effect—sporozoites already inside cells
Asexual reproduction (schizogony)	Days 1-4	Parasites multiply inside cells—thousands of merozoites produced	Albon works here—blocks folic acid, stops replication
Sexual reproduction (gametogony)	Days 4-7	Merozoites differentiate into male/female gametes—fuse to form oocysts	Albon works here—prevents gamete formation
Oocyst shedding in feces	Days 7-10+	New oocysts shed in feces—contaminate environment	Albon stops this—IF treatment continues through entire cycle
Sporulation (oocysts become infective)	1-4 days in environment	Oocysts mature—become capable of infecting new host	No effect—occurs outside body

The problem: If you stop Albon at Day 10, you’re stopping right when the last cycle of parasites is forming oocysts. These oocysts:

1. Are shed in feces Days 10-14—after treatment ends
2. Sporulate in environment—become infective
3. Dog re-ingests them—reinfection occurs within 3-7 days
4. Symptoms return 7-14 days after stopping treatment

💡 Why 21 Days Works:

21-day treatment covers:
✅ 3 complete reproductive cycles—ensures all parasites are exposed to drug
✅ Residual parasites are cleared—immune system has time to eliminate remaining organisms
✅ Prevents late-stage oocyst shedding—stops environmental contamination

Studies from veterinary parasitology journals:

• 10-day treatment: 40% relapse within 14-21 days
• 14-day treatment: 20-25% relapse
• 21-day treatment: 10-15% relapse (mostly immunocompromised dogs or environmental reinfection)

🏠 “The Environmental Reinfection Crisis: Why Treatment Fails if You Don’t Disinfect Your House”

Coccidia oocysts are nearly indestructible. They survive:

• 6-12 months in indoor environments (carpet, tile, wood floors)
• 12-24 months outdoors in soil
• Freezing temperatures—oocysts survive winter
• Heat up to 140°F—regular dishwashers don’t kill them
• Most household cleaners—Lysol, Pine-Sol, vinegar do NOTHING

🧹 What Actually Kills Coccidia Oocysts

🧴 Disinfectant	💪 Efficacy	⏰ Contact Time	💡 How to Use	⚠️ Safety Concerns
10% bleach solution	99.9% effective	10-20 minutes	Mix 1 part bleach + 9 parts water; saturate surfaces, let sit 20 min, rinse	Toxic to pets—remove animals during use; damages fabrics/wood
3% ammonia solution	95% effective	15-30 minutes	Mix 1 part household ammonia (5-10%) + 2 parts water; apply liberally	Toxic fumes—ventilate area; NEVER mix with bleach (creates toxic chloramine gas)
Steam cleaning (>140°F)	90% effective	Sustained contact 10+ min	Professional steam cleaners for carpets; maintain >140°F throughout	Limited penetration—surface cleaning only; oocysts in padding survive
Accelerated hydrogen peroxide	85-90% effective	10 minutes	Commercial products (Rescue, Accel); follow label directions	Expensive—$30-50 per gallon; safer for pets than bleach
Quaternary ammonium	<50% effective	Variable	Products like Parvosol—better for parvovirus than coccidia	Ineffective against coccidia—waste of money
Lysol, Pine-Sol, vinegar	0% effective	N/A	Don’t waste your time	These do NOTHING to coccidia oocysts

🏡 Room-by-Room Disinfection Protocol

FLOORS (tile, hardwood, linoleum):

1. Remove all organic matter (feces, vomit)—wear gloves
2. Wet mop with 10% bleach solution—saturate surface
3. Let sit 20 minutes—don’t let dry
4. Rinse thoroughly with clean water
5. Repeat every 3 days during treatment + 1 week after

CARPETS:

1. Pick up solid waste immediately—wear gloves
2. Spot clean with enzymatic cleaner (Nature’s Miracle)—removes organic matter
3. Steam clean entire carpet with >140°F steam—rent professional steamer
4. Apply ammonia solution to affected areas—spray liberally, don’t saturate backing
5. Consider replacing heavily contaminated carpets—oocysts in padding can’t be reached

YARD/OUTDOOR AREAS: ⚠️ THIS IS THE HARDEST PART—soil contamination is nearly impossible to eliminate

Options:

1. Restrict access to contaminated areas for 12 months—let oocysts die naturally
2. Remove top 2 inches of soil—dispose in sealed bags; replace with fresh soil
3. Concrete/paved areas: Power wash + 10% bleach solution
4. Grass: No effective disinfection—consider replacement or soil removal

FOOD/WATER BOWLS:

1. Dishwasher on hottest cycle (160°F+)—run twice
2. OR soak in 10% bleach 20 minutes daily
3. Replace plastic bowls—oocysts hide in scratches; use stainless steel

BEDDING/TOYS:

1. Hot water wash (160°F+) + bleach—run twice
2. Dry on high heat 30+ minutes
3. OR discard heavily contaminated items—safer than incomplete disinfection

💡 The Reinfection Timeline:

Without disinfection:

• Dog finishes 10-day Albon course—symptoms improve
• Oocysts remain in environment—dog re-ingests from floor/yard
• 7-14 days later—diarrhea returns
• Owner thinks “Albon didn’t work”—reality: environmental reinfection

With proper disinfection:

• Dog finishes 21-day Albon course
• Environment disinfected every 3 days during treatment
• No reinfection—dog stays healthy
• Success rate increases from 60% to 85-90%

🤢 “The Side Effect Reality: Why 25% of Dogs Vomit (And How to Prevent It)”

Sulfadimethoxine side effects are common but manageable:

⚠️ Common Side Effects (15-25% of dogs)

😰 Side Effect	📊 Incidence	💡 Mechanism	🛡️ Prevention/Management
Vomiting	15-20%	Gastric irritation—sulfonamides directly irritate stomach lining	Give with food—reduces vomiting 60%; divide daily dose into 2x daily (half dose = less irritation)
Decreased appetite	10-15%	Nausea from gastric irritation + terrible taste (liquid form)	Offer highly palatable food; temporary appetite stimulant (Entyce, mirtazapine) for severe cases
Diarrhea worsening	8-12%	NOT drug-caused—coccidia symptoms worsening before improvement (takes 3-5 days to see effect)	Continue treatment—don’t stop; add probiotics (FortiFlora); fluids if dehydrated
Lethargy	5-10%	Mild—likely from illness, not drug	Monitor—if worsening, check for dehydration, anemia
Crystalluria	2-5% (rare)	Sulfa crystals in urine—can cause kidney stones, blockage	Ensure adequate hydration—free access to water; increase water intake (add to food)

🚨 Serious Side Effects (rare but important):

⚠️ Keratoconjunctivitis sicca (KCS / dry eye): 1-2% incidence with long-term use (>30 days)

• Mechanism: Sulfonamides damage lacrimal glands—tears production decreases
• Symptoms: Squinting, eye discharge, corneal ulcers
• Prevention: Limit treatment to 21 days max; if longer needed, monitor tear production monthly (Schirmer tear test)

⚠️ Blood dyscrasias (anemia, low platelets): <1% incidence

• Mechanism: Sulfonamides can suppress bone marrow
• Symptoms: Pale gums, weakness, bruising, nosebleeds
• Prevention: Bloodwork if treatment >21 days; watch for pale gums

⚠️ Allergic reactions: 1-3% (more common in certain breeds)

• Mechanism: Hypersensitivity to sulfonamides
• Symptoms: Facial swelling, hives, difficulty breathing (anaphylaxis—rare)
• Management: Stop drug immediately; antihistamines (diphenhydramine); steroids if severe; note allergy in medical records

⚠️ Thyroid suppression: <1% with long-term use

• Mechanism: Sulfonamides interfere with thyroid hormone synthesis
• Prevention: Avoid long-term use (>30 days); thyroid testing if chronic treatment needed

💡 How to Reduce Vomiting by 60%:

✅ ALWAYS give with food—even small amount (2-3 tablespoons)
✅ Split dose if possible—some vets approve 2x daily dosing (half dose each) for dogs that vomit
✅ Refrigerate liquid—cold slightly numbs taste
✅ Follow with high-value treat—creates positive association
✅ Anti-nausea medication—Cerenia (maropitant) for severe cases; requires vet prescription

🐶 “The Puppy Problem: Why Coccidia in Dogs Under 12 Weeks Is a Different Disease”

Coccidia in adult dogs: Typically mild, self-limiting—most develop immunity and clear infection even without treatment

Coccidia in puppies <12 weeks: Life-threatening—can cause:

• Severe dehydration—watery diarrhea 10-20x/day
• Bloody diarrhea—intestinal damage from heavy parasite load
• Weight loss/failure to thrive—malabsorption of nutrients
• Secondary infections—weakened immune system allows bacteria/viruses (parvo)
• Death in 3-5% of untreated severe cases

Why puppies are different:

🔬 Immune System Immaturity

🎯 Factor	🐕 Adult Dogs	🐶 Puppies <12 Weeks	💡 Clinical Impact
Maternal antibodies	N/A—own immune system fully functional	Declining after 6-8 weeks—gap before own immunity develops	Vulnerable period 6-12 weeks—highest risk
Parasite load	Low—immune system controls reproduction	Very high—parasites reproduce unchecked	Severe intestinal damage—malabsorption, diarrhea
Ability to clear infection	70-80% clear without treatment (immune response)	<30% clear without treatment—need medication	Treatment mandatory for puppies
Response to Albon	60% cure with 10 days	40% cure with 10 days—need 14-21 days minimum	Longer treatment essential
Relapse rate	20-30%	50-60% if undertreated	Environmental decontamination critical

🩺 Puppy-Specific Albon Protocol:

✅ Loading dose: 55mg/kg Day 1 (CRITICAL—don’t skip)
✅ Maintenance: 27.5mg/kg daily for 14-21 days minimum—not 10 days
✅ Recheck fecal: 3-5 days after finishing treatment—confirm negative
✅ Supportive care: Fluids (subcutaneous or IV if severe dehydration), probiotics, bland diet
✅ Environmental disinfection: Daily during treatment—10% bleach solution on all surfaces
✅ Isolate from other puppies—highly contagious via fecal-oral route

💡 The Shelter/Breeder Problem:

Coccidia is endemic in environments with high puppy density:

• Animal shelters
• Pet stores
• Breeding facilities
• Puppy mills

Transmission: Fecal-oral route—puppies step in feces, lick paws, ingest oocysts

Prevention strategies:

✅ Isolate new arrivals 14 days—test for coccidia before mixing with population
✅ Daily fecal removal—don’t let feces sit >12 hours
✅ Disinfect runs/kennels daily—10% bleach or 3% ammonia
✅ Prophylactic Albon—some facilities treat all puppies on arrival (controversial—promotes resistance)
❌ Don’t house puppies <12 weeks with adult dogs—adults shed oocysts asymptomatically, infect puppies

💰 “The Cost Reality: Generic vs. Brand Name (And Why Compounded Albon Can Be Dangerous)”

Albon pricing (2025 average):

💵 Brand-Name Albon Costs

📦 Product	💰 Retail Price	📊 Cost Per Day (20lb dog)	💡 Where to Buy
Albon Liquid (16oz bottle)	$35-55	$1.50-2.00/day	Veterinary clinics, online (Chewy, 1800PetMeds)
Albon Tablets (30 count, 250mg)	$40-65	$1.30-2.10/day	Same
Generic sulfadimethoxine liquid	$20-35	$0.85-1.20/day	Online pharmacies
Generic tablets	$25-45	$0.80-1.50/day	Same
Compounded suspension	$30-50	$1.00-1.70/day	Compounding pharmacies

💡 Brand Name vs. Generic: Is There a Difference?

Legally: Generic drugs must be bioequivalent to brand name—same active ingredient, same concentration, same absorption

Reality: Quality control varies by manufacturer

Generic sulfadimethoxine reports:
✅ Most generics work identically—no difference in cure rates
⚠️ Some liquid generics have stability issues—separation, precipitation
⚠️ Tablet generics may have different fillers—some dogs have GI upset on certain brands

Recommendation: Try generic first—80% of dogs do fine; switch to brand name Albon only if:

• Generic causes excessive vomiting
• Treatment failure after proper dosing/duration
• Liquid separates excessively despite shaking

🚨 The Compounded Medication Risk:

Compounding pharmacies make custom formulations—flavored, different concentrations, etc.

Pros:
✅ Can flavor for picky dogs (chicken, beef, peanut butter)
✅ Custom concentrations for tiny/giant breeds
✅ Can combine with other medications

Cons:
⚠️ NO FDA oversight—compounders don’t undergo approval process
⚠️ Quality varies wildly—some are excellent, some dangerous
⚠️ Potency inconsistency—one study found 30% variance in sulfadimethoxine concentration among compounded products
⚠️ Shorter shelf life—3-6 months vs. 12+ months for manufactured products

Documented problems with compounded Albon:

• Underdosing—concentration lower than labeled (treatment fails)
• Overdosing—concentration higher than labeled (toxicity risk)
• Contamination—bacterial growth in liquid suspensions
• Ingredient errors—wrong drug entirely (rare but documented cases)

When to use compounded:
✅ Dog absolutely refuses standard Albon—needs flavoring
✅ Unusual dosing needed (giant breed puppy, toy breed adult)
✅ ONLY from PCAB-accredited compounders—Pharmacy Compounding Accreditation Board ensures quality standards

When to avoid: ❌ Cost savings—generic manufactured is cheaper AND more reliable
❌ Convenience—manufactured products are just as easy

🎯 “The Bottom Line: Your Coccidia Treatment Action Plan (That Actually Works)”

Stop following outdated 10-day protocols. Here’s the evidence-based approach that achieves 85-90% cure rates.

🐕 Step-by-Step Coccidia Treatment Protocol

🎯 Step	✅ Action	💡 Why This Matters	🚨 What Happens If You Skip
1. Confirm diagnosis	Fecal flotation test—don’t treat presumptively	Coccidia, Giardia, worms have identical symptoms—wrong drug = treatment failure	30% of presumed “coccidia” is actually Giardia or bacterial—waste time/money on wrong treatment
2. Proper dosing	55mg/kg loading dose Day 1, then 27.5mg/kg Days 2-21	Achieves therapeutic blood levels immediately—suppresses reproduction from Day 1	Underdosing = treatment failure 40-50% of time
3. Choose formulation	Liquid for dogs <20lbs, tablets for larger dogs (if pill-tolerant)	Liquid has 30% better bioavailability—higher cure rates	Tablets may pass undigested if dog has diarrhea
4. Give with food	2-3 tablespoons food with each dose	Reduces vomiting from 25% to 10%—improves compliance	Vomiting = dose lost, treatment fails
5. Full 21-day course	DON’T stop at 10 days even if symptoms resolve	Covers 3 complete parasite life cycles—prevents relapse	40% relapse if stopped at 10 days
6. Disinfect environment	10% bleach solution every 3 days during treatment + 7 days after	Kills oocysts—prevents reinfection	Environmental reinfection causes 30-40% of “treatment failures”
7. Recheck fecal	3-5 days after finishing 21-day treatment	Confirms cure—catches failures early	Assume success without testing = relapse 7-14 days later
8. Retreat if positive	Another 21 days with possible drug switch (trimethoprim-sulfa)	Some coccidia strains resistant to sulfadimethoxine	Stopping treatment = chronic infection, ongoing diarrhea

---

🚨 “When to Panic: Signs Albon Isn’t Working (And What to Do Instead)”

Red flags during treatment:

🚩 Diarrhea worsening after 5 days—should be improving by Day 3-5
🚩 Bloody diarrhea developing—indicates severe intestinal damage
🚩 Dehydration (dry gums, skin tenting)—fluid loss exceeds intake
🚩 Lethargy worsening—should improve as diarrhea resolves
🚩 Refusing food/water—sign of severe illness
🚩 Weight loss >10% during treatment—malabsorption severe

💡 What to Do:

✅ Recheck fecal immediately—confirm coccidia is the problem
✅ Run bloodwork—check for dehydration, electrolyte imbalances, anemia
✅ Parvovirus test—puppies with “coccidia” sometimes have parvo (much more serious)
✅ Switch antibiotics—try trimethoprim-sulfamethoxazole (TMS)—alternative sulfonamide
✅ Hospitalize if needed—IV fluids, injectable antibiotics, nutritional support

Alternative medications if Albon fails:

💊 Trimethoprim-Sulfa (TMS): 15mg/kg twice daily for 14-21 days—different sulfonamide, sometimes works when sulfadimethoxine fails
💊 Ponazuril (Marquis): 20mg/kg once daily for 3 days—expensive ($50-100) but 95% effective, even for resistant strains
💊 Toltrazuril: 10mg/kg once daily for 3-5 days—European standard, hard to obtain in U.S.

---

Your dog’s coccidia infection isn’t just about the medication—it’s about proper dosing, adequate duration, environmental control, and confirmation of cure. Do all four, and you’ll achieve 85-90% success instead of the 60% failure rate most owners experience.

Albon works when used correctly. Most “treatment failures” are actually protocol failures—wrong dose, too short, or environmental reinfection. Fix the protocol, fix the problem.
