Zesty Paws Calming Bites come in two very different formulas. The standard chew is a broad multi-herb blend with no melatonin; the Advanced version adds melatonin — but inside a proprietary blend that does not disclose the melatonin amount. If knowing your dog’s exact melatonin dose matters to you, that is a real drawback.
Ownership disclosure: This website is owned and operated by Pure Majesty Pets, which makes and sells a melatonin liquid for dogs that we mention in our comparisons. We rank and describe products using their labeled ingredients and published research, not paid placement — but you should read our owned-product coverage with that relationship in mind.

What the current label lists
| Version | Melatonin? | Notable labeled actives |
|---|---|---|
| Standard Calming Bites | No | Hemp seed, chamomile, valerian, passionflower, Suntheanine, ginger, ashwagandha, L-tryptophan, magnesium citrate (named on current label) |
| Advanced Calming Bites | Yes — amount not disclosed | Chamomile 160 mg, Proprietary Relaxation Blend 150 mg (valerian, L-tryptophan, melatonin), hemp 100 mg, passionflower 90 mg, Suntheanine 60 mg |
Strengths
- Broad multi-herb formula for owners who want a treat format with many botanicals.
- The Advanced version discloses several actives with amounts (chamomile, Suntheanine).
- Suntheanine (L-theanine) has supportive situational dog evidence (Pike 2015).
Limitations
- The Advanced version hides the melatonin amount inside a 150 mg proprietary blend — you cannot see how much melatonin your dog gets.
- The standard chew contains no melatonin, which surprises some buyers.
- Labels and SKUs vary; always confirm the exact product you are buying.
Always screen inactive ingredientsActives are only half the label. Read the inactive ingredients and reject anything containing xylitol (FDA), especially in flavored or human products.

Pure Majesty publishes this six-active formula on its product page (labeled per 1 mL, updated July 2026); confirm the panel printed on the bottle you receive. Ingredient amounts describe what is in the bottle; they do not by themselves prove a calming or sleep outcome, and this exact six-active blend has not been tested in a published canine clinical trial.
Frequently asked questions
Do Zesty Paws Calming Bites contain melatonin?
The standard Calming Bites do not. The Advanced Calming Bites do, but the melatonin sits inside a 150 mg proprietary blend, so the exact amount is not disclosed.
How much melatonin is in Zesty Paws Advanced?
The label does not say — melatonin is combined with valerian and L-tryptophan in a 150 mg proprietary blend. If you need a known melatonin amount, a product that discloses it is preferable.
Are Zesty Paws Calming Bites safe?
As with any product, read the full label including inactives and avoid xylitol. Discuss with your vet, especially if your dog is on medication.
