| What’s the biggest hidden risk? | Drug interactions—especially with selegiline (Anipryl) and certain flea products containing amitraz |
| How long does it take to work? | 30 minutes to 1 hour—short duration of 4-6 hours |
🔬 1. The FDA Has Never Approved This Product for Efficacy—Here’s Why That Matters
Let’s start with the uncomfortable truth the industry doesn’t advertise: pet supplements in the United States are NOT regulated like human supplements. When Congress passed the Dietary Supplement Health and Education Act (DSHEA) in 1994, it explicitly excluded animals. The FDA confirmed this in a 1996 Federal Register notice.
What does this mean for NaturVet Quiet Moments?
| 🏭 Regulatory Reality | 🔍 What This Means for You |
|---|---|
| No pre-market approval required | NaturVet does not have to prove this product works before selling it |
| NASC Quality Seal is voluntary | It indicates manufacturing standards, NOT clinical efficacy 📋 |
| Structure/function claims only | NaturVet can say “supports relaxation” but cannot legally claim it “treats anxiety” |
| No standardized potency testing | Melatonin content may vary between batches—studies show supplements often differ from label claims |
💡 Expert Insight: NaturVet is manufactured in an FDA-registered, cGMP-compliant facility, which is better than many competitors. However, “veterinarian formulated” does not mean “clinically proven effective.” These are marketing terms, not regulatory standards.
💊 2. The Melatonin Dose Is Surprisingly Low—Is It Even Therapeutic?
Each 2-chew serving of NaturVet Quiet Moments contains 120 mcg of melatonin. Let’s put that in perspective.
| 🐕 Dog Weight | 💊 Typical Veterinary Melatonin Dose | 🍪 NaturVet Quiet Moments Dose (2 chews) |
|---|---|---|
| Under 25 lbs | 1-3 mg | 0.12 mg (120 mcg) ⚠️ |
| 25-100 lbs | 3-6 mg | 0.12 mg |
| Over 100 lbs | 6+ mg | 0.12 mg |
The math reveals a startling gap: the melatonin dose in NaturVet Quiet Moments is 8-50 times lower than what veterinarians typically prescribe for anxiety or sleep support. For a 50-pound dog, vets commonly recommend 3 mg of melatonin—you’d need to give approximately 25 doses of Quiet Moments to reach that amount.
🧠 Pro Insight: This doesn’t necessarily mean the product is ineffective. The formula relies on a synergistic blend of six ingredients. However, if your dog has moderate to severe anxiety, this melatonin dose alone is unlikely to produce significant effects. The American Kennel Club notes that melatonin “shouldn’t be viewed as a miracle cure” for complex anxiety issues.
🧪 3. L-Tryptophan: The Science Is More Mixed Than Marketing Suggests
NaturVet Quiet Moments contains 30 mg of L-tryptophan per 2 chews—an amino acid precursor to serotonin. The marketing suggests this ingredient “helps reduce stress and tension.” But what does the research actually show?
| 📚 Study | 🔬 Finding | ⭐ Evidence Strength |
|---|---|---|
| Veterinary Evidence (2024) | One study found NO overall significant influence of tryptophan on anxiety in home conditions | Moderate |
| DeNapoli et al. (2000) | Showed reduced territorial aggression with low-protein diet + tryptophan | Weak (specific conditions) |
| Kato et al. (2012) | Combined tryptophan + alpha-casozepine showed stress reduction | Moderate (combination product) |
| Frontiers in Veterinary Science (2025) | Studies on L-tryptophan alone have had “mixed results” | Mixed |
⚠️ Critical Note: A 2024 systematic review published in Veterinary Evidence concluded that the evidence for dietary tryptophan supplementation reducing anxiety in dogs is “moderate” at best—with one well-designed study showing no significant effect.
The dose matters enormously. Research showing positive results typically used 1.45 g/kg of diet—far higher concentrations than what’s found in calming chews. At 30 mg per serving, NaturVet provides a fraction of studied therapeutic doses.
🌿 4. Chamomile and Passion Flower—Traditional Remedies Without Robust Canine Data
NaturVet includes 150 mg chamomile and 100 mg passion flower per 2-chew serving. Both herbs have centuries of traditional use for calming in humans. But here’s what the industry doesn’t tell you:
| 🌸 Ingredient | 🧬 Human Evidence | 🐕 Canine Evidence | 🚨 Concerns |
|---|---|---|---|
| Chamomile | Moderate for mild anxiety | Very limited | Can cause allergic reactions in ragweed-sensitive dogs |
| Passion Flower | Some positive anxiety trials | Almost none | Safety in dogs not well-established long-term |
💡 What Vets Know: Neither chamomile nor passion flower has been subjected to rigorous, peer-reviewed clinical trials specifically in dogs for anxiety. Their inclusion is based largely on traditional use and extrapolation from human data.
🍬 5. Ginger Is Here for Your Dog’s Stomach—Not Their Brain
At 100 mg per serving, ginger is included to “support sensitive stomachs.” This is actually the most evidence-based claim in the entire formula.
Why? Because anxious dogs often vomit or experience GI distress, especially during car rides. Ginger genuinely can help settle nausea. But it has no direct calming effect on anxiety pathways.
🚗 Best Use Case: If your dog has motion sickness + travel anxiety, the ginger component makes Quiet Moments a reasonable choice. But if your dog is primarily anxious without GI symptoms, ginger adds minimal value.
⚠️ 6. The Drug Interaction Warning Nobody Reads—Serotonin Syndrome Is Real
Buried in the fine print of NaturVet’s label is a critical caution: “Caution with concomitant use of MAO inhibitors and sedatives.”
This isn’t boilerplate language. It’s a serious warning that most pet owners gloss over.
| 💊 Medication Class | 🔬 Examples | 🚨 Risk with Quiet Moments |
|---|---|---|
| MAO Inhibitors | Selegiline (Anipryl) for cognitive dysfunction | High—can trigger serotonin syndrome |
| Certain Flea Products | Products containing amitraz | Moderate—amitraz has MAO inhibitor activity |
| SSRIs | Fluoxetine (Reconcile), sertraline | Moderate to high—additive serotonin effects |
| Tricyclic Antidepressants | Clomipramine (Clomicalm), amitriptyline | Moderate—combined serotonin boost |
| Tramadol | Common pain reliever | Moderate—tramadol affects serotonin reuptake |
Serotonin syndrome symptoms in dogs include: vomiting, diarrhea, dilated pupils, panting, muscle tremors, rigidity, or seizures. One veterinarian noted that tryptophan overdose “can lead to symptoms associated with serotonin syndrome” that may persist for 24 hours or longer.
🔴 Critical Warning: If your dog takes ANY prescription anxiety medication, behavior medication, or certain pain medications, do not give calming supplements without explicit veterinary approval. This isn’t overcautious—it’s medically necessary.
🤰 7. Not Safe for Pregnant, Nursing, or Breeding Dogs
The label states: “Safe use in pregnant animals or animals intended for breeding has not been proven.”
This isn’t just legal cover—there’s genuine scientific concern. Melatonin influences reproductive hormones. Research on melatonin’s effects on canine reproduction is insufficient to guarantee safety. If your dog is pregnant, nursing, or intended for breeding, skip this product entirely.
📊 8. Real Owner Experiences—The Honest Mixed Reviews
Based on thousands of verified reviews across multiple platforms, here’s what dog owners actually experience:
| 📈 Outcome | 📊 Approximate Percentage | 🗣️ Common Comments |
|---|---|---|
| Works well for mild anxiety | ~40-50% | “Takes the edge off,” “helps him settle” |
| Works for sleep/bedtime | ~25-30% | “Finally sleeps through the night” ✅ |
| No noticeable effect | ~20-30% | “My Lab showed zero change after weeks of use” |
| Caused GI upset | ~5-10% | “Runny stool,” “soft poop” |
| Paradoxical reaction | ~1-3% | “Made my dog more agitated,” “growling and snappy” ⚠️ |
💡 Pattern Recognition: Quiet Moments appears most effective for:
- Mild anxiety (not severe separation anxiety or phobias)
- Nighttime settling and sleep support
- Young puppies adjusting to crate training
- Pre-grooming or pre-nail trim calming
It appears LEAST effective for:
- Severe thunderstorm phobia
- Serious separation anxiety
- Highly reactive dogs
- Older dogs with established anxiety patterns

| 180 soft chews | $30-38 | ~$0.67-0.84 (4 chews daily) | $20-25 |
Compare this to prescription alternatives:
| 💊 Product | 📅 Monthly Cost | 🔬 FDA Status |
|---|---|---|
| Sileo (dexmedetomidine) | $60-100 | FDA-approved ✅ |
| Clomicalm (clomipramine) | $30-80 | FDA-approved ✅ |
| Trazodone (generic) | $15-40 | Used off-label, well-studied |
| Quiet Moments | $20-31 | Not FDA-evaluated |
🛠️ 11. How to Use Quiet Moments for Best Results
If you decide to try NaturVet Quiet Moments, maximize your chances of success:
| 🐕 Dog Weight | 💊 Recommended Dose | ⏰ Timing | 🔄 Maximum Frequency |
|---|---|---|---|
| Up to 26 lbs | 1 chew | 30 min before stressor | Do not exceed 2 chews per 12 hours |
| 27-50 lbs | 2 chews | 30 min before stressor | Do not exceed 4 chews per 12 hours |
| 51-99 lbs | 4 chews | 30 min before stressor | Do not exceed 8 chews per 12 hours |
| 100+ lbs | 6 chews | 30 min before stressor | Do not exceed 12 chews per 12 hours |
🧠 Pro Tips:
- Trial run first: Give the product on a calm day at home before using it for an actual stressor
- Feed with food: Give after eating to reduce GI upset
- Don’t expect miracles: This is a mild supplement, not a sedative
- Combine with training: Supplements work best alongside desensitization and counterconditioning
🚨 12. What to Do If Your Dog Eats the Entire Jar
Accidental ingestion is surprisingly common—these chews are tasty. Here’s what vets say:
| 🐕 Scenario | 🩺 Action Required | ⚠️ Symptoms to Watch |
|---|---|---|
| Small amount over recommended dose | Monitor at home | Mild drowsiness, soft stool |
| 2-3x recommended dose | Monitor closely | Lethargy, vomiting, diarrhea |
| Large quantity (15+ chews for small dog) | Contact vet or poison control | Serotonin syndrome signs (tremors, panting, dilated pupils, rigidity) |
| Entire jar | Contact vet immediately | Above symptoms plus potential GI obstruction from chew mass |
📞 Poison Control Numbers:
- ASPCA Animal Poison Control: (888) 426-4435
- Pet Poison Helpline: (855) 764-7661
Veterinarians note that Quiet Moments has a “very high margin of safety”—it’s more food supplement than medication. However, massive overdoses can trigger serotonin-related symptoms lasting 24+ hours.

FAQs
💬 “My vet said I could use this with Prozac—is that really safe?”
This requires careful consideration. Fluoxetine (Prozac/Reconcile) is a selective serotonin reuptake inhibitor that increases serotonin levels. NaturVet Quiet Moments contains L-tryptophan, a serotonin precursor. Combining them creates additive serotonin effects.
| 🔬 Risk Factor | 🩺 Consideration | ⚠️ Recommendation |
|---|---|---|
| Low dose of tryptophan (30 mg) | Relatively small additional serotonin load | Risk likely low but not zero |
| Individual sensitivity varies | Some dogs are more susceptible to serotonin effects | Monitor for agitation, tremors, GI upset |
| Your vet knows your dog | They’ve assessed the specific risk for your pet | Follow their guidance, but watch for serotonin symptoms |
Some veterinarians do approve this combination, especially at lower doses. However, if your dog shows any signs of agitation, tremors, dilated pupils, or unusual behavior after starting the combination, discontinue and contact your vet immediately.
💬 “The hemp version didn’t work as well as the regular formula—why?”
Several owners have reported this exact experience. The hemp version contains hemp seed oil instead of some other ingredients, but the calming herb profile remains similar.
| 🌿 Potential Explanation | 🔬 Details |
|---|---|
| Hemp seed contains NO CBD | Hemp seed oil has omega fatty acids but no significant cannabidiol content |
| Individual dog response | Some dogs may respond differently to formulation changes |
| Expectation mismatch | Pet owners may expect CBD-like effects from hemp seed, which won’t occur |
| Batch variation | Manufacturing variability exists in all supplements |
The hemp seed in NaturVet products is NOT the same as CBD. Hemp seed provides nutritional fatty acids but has no anxiolytic compounds. If you want cannabidiol specifically, you need a different product entirely.
💬 “How is this different from prescription Sileo or trazodone?”
The difference is fundamental: mechanism of action, predictability, and evidence base.
| 💊 Product | 🧬 Mechanism | 📚 Evidence Level | 💉 Regulation |
|---|---|---|---|
| NaturVet Quiet Moments | Multiple weak pathways (serotonin, GABA, general calming) | Minimal clinical trials | Not FDA-evaluated |
| Sileo | Alpha-2 adrenergic agonist—directly reduces norepinephrine release | FDA-approved clinical trials | FDA-approved for noise aversion ✅ |
| Trazodone | Serotonin antagonist and reuptake inhibitor | Extensive veterinary literature | Prescription, well-studied |
💡 The Core Difference: Prescription medications have defined, studied mechanisms with predictable effects. Quiet Moments provides a cocktail of ingredients with individually weak evidence, hoping the combination produces results. Sometimes it does. Sometimes it doesn’t. You’re essentially experimenting on your own dog.
💬 “Why does the label say ‘veterinarian formulated’ if vets don’t recommend it?”
“Veterinarian formulated” means a veterinarian was involved in creating the formula. It does NOT mean:
- All veterinarians recommend it
- Clinical trials prove efficacy
- It meets pharmaceutical standards
- The formula is optimal
Many veterinarians DO recommend Quiet Moments as a low-risk, first-line option for mild anxiety. Others consider it essentially a very expensive placebo. The term is a marketing claim, not a clinical endorsement.
💬 “My dog became MORE anxious after taking this—is that possible?”
Yes, paradoxical reactions occur in approximately 1-3% of dogs based on review data. Possible explanations:
| 🔬 Mechanism | 📋 Explanation |
|---|---|
| Histamine sensitivity | Chamomile can trigger histamine release in sensitive dogs |
| Individual neurochemistry | Some dogs respond paradoxically to calming compounds |
| GI discomfort causing stress | Upset stomach can increase anxiety |
| Expectation vs. reality | Owner stress about whether it’s working transfers to dog |
If your dog becomes more agitated, stop the supplement immediately. This is not a product that will “build up” to effectiveness—if it causes negative reactions, it’s not the right choice for your dog.
💬 “Is the NASC Quality Seal meaningful?”
The National Animal Supplement Council seal indicates:
| ✅ What NASC Seal Means | ❌ What NASC Seal Does NOT Mean |
|---|---|
| Passed manufacturing quality audit | Product works as claimed |
| Uses good manufacturing practices | Clinical trials support claims |
| Has adverse event reporting system | FDA has reviewed or approved product |
| Labels meet NASC guidelines | Ingredients are at therapeutic doses |
The NASC seal is valuable for ensuring you’re getting a quality-controlled product, but it provides zero guarantee of efficacy. It’s a process certification, not an outcome certification.
💬 “What’s the best alternative if this doesn’t work?”
The evidence-based ladder for canine anxiety:
| ⭐ Step | 💊 Intervention | 📚 Evidence |
|---|---|---|
| 1 | Behavior modification training | Strong ✅ |
| 2 | Environmental management (Thundershirt, white noise) | Moderate |
| 3 | Pheromone therapy (Adaptil) | Moderate |
| 4 | Veterinary calming diet (Royal Canin CALM) | Moderate |
| 5 | Prescription medication (discuss with vet) | Strong ✅ |
🧠 Expert Recommendation: If NaturVet Quiet Moments doesn’t work after 2-3 weeks of consistent use, it’s time for a veterinary behavior consultation—not a different supplement brand. Continuing to cycle through OTC calming chews delays appropriate treatment for dogs with genuine anxiety disorders.
