Per chew: chamomile 75 mg, thiamine 50 mg, passion flower 50 mg, ginger 50 mg, L-tryptophan 15 mg, and melatonin 60 mcg.
What the evidence says
L-theanine has two small dog studies with maker ties and positive but limited results. See our L-theanine guide.
Melatonin is widely used by vets for noise fear and sleep, usually at doses far higher than 60 mcg (often 1 to 6 mg depending on size). Evidence in dogs is mostly case reports and clinical experience rather than controlled trials. See our melatonin guide.
L-tryptophan is a serotonin precursor. Diet studies show mixed effects on dog behavior, usually at doses much larger than 15 mg. See our L-tryptophan guide.
Herbs and hemp seed. Passionflower, valerian, chamomile, and ashwagandha have little or no controlled dog data. Hemp seed powder is not CBD. See our botanicals guide and hemp seed vs CBD guide. Neither brand cites a published trial of its finished chew.
Dosing by weight (from the labels)
| Dog weight | Zesty Paws | NaturVet Quiet Moments |
|---|---|---|
| Up to 25 lb | 1 chew | 1 chew (up to 26 lb) |
| 26 to 50 lb | 2 chews | 2 chews (27 to 50 lb band) |
| 51 to 75 lb | 2 chews | 4 chews (51 to 99 lb band) |
| Over 75 lb | 3 chews | 4 chews up to 99 lb; 6 chews at 100 lb and up |
Zesty Paws listings suggest starting at half the dose. NaturVet says to give the dose about 30 minutes before a stressful event and not to exceed double the dose in 12 hours (label maximum; ask your vet before going above a single dose).
Onset and daily vs situational use
Quiet Moments is built for situational use: the label timing is 30 minutes ahead, and melatonin's effect tends to be short. Zesty Paws is sold as a routine daily chew, although owners also use it before events. Neither label promises a specific duration.
Who should choose which
- Small dogs: both give one chew to small dogs (Zesty Paws up to 25 lb, NaturVet up to 26 lb).
- Storms and fireworks: Quiet Moments, for its melatonin and stated pre-event timing.
- Daily stress: Zesty Paws, if you want to avoid daily melatonin.
- Sensitive stomach: Quiet Moments has a shorter active list. Zesty Paws has many botanicals plus hemp seed, which is more to react to.
- Dogs on medication: melatonin, tryptophan, valerian, and ashwagandha can all interact with sedatives or serotonin drugs. Talk to your vet first.
Frequently asked questions
Does NaturVet Quiet Moments make dogs sleepy?
It can. Each chew lists about 60 mcg of melatonin, and owners sometimes describe a drowsy or relaxed dog for a few hours. That is often the goal at bedtime or during fireworks. If drowsiness is a problem for daytime use, a melatonin-free chew such as Zesty Paws Calming Bites may suit better.
Is the hemp in Zesty Paws Calming Bites CBD?
No. The label lists organic hemp seed powder, which contains essentially no CBD. Hemp seed adds fats and fiber but is not a proven calming ingredient. Products that contain CBD state cannabidiol content separately, usually in mg. Each chew has 50 mg hemp seed powder. Our hemp seed vs CBD guide explains how to tell the difference on a label.
Which has more L-theanine?
Zesty Paws Calming Bites include L-theanine in a 105 mg proprietary blend but do not disclose how much. NaturVet Quiet Moments does not list L-theanine as an active; it relies on L-tryptophan, melatonin, and chamomile instead. If L-theanine is the ingredient you want, Zesty Paws is the only one of these two that includes it, though you won't know the dose.
Is daily use OK for either one?
Both brands allow routine use, though Quiet Moments is more often used before events because of its melatonin. Zesty Paws publishes daily chew counts by weight. Long-term daily melatonin is best discussed with a vet, especially for dogs with hormone-related conditions or dogs already taking other medication.
