Pet Naturals Calming is a simple, transparent three-active chew at a smaller size than some competitors. It discloses each amount per 1.5 g chew and contains no melatonin. The amounts are modest, which suits mild situational stress rather than significant anxiety.
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. Read the full disclosure.
What the current label lists
| Active | Per chew (1.5 g) |
|---|---|
| Thiamine (Vitamin B1) | 35 mg |
| Colostrum Calming Complex (biopeptide blend) | 5 mg |
| L-theanine | 5 mg |
Strengths
- Fully transparent — every active is disclosed with an amount.
- Small chew size can suit smaller dogs and easy dosing.
- Contains L-theanine, which has supportive situational dog evidence (Pike 2015).
Limitations
- Amounts are modest (L-theanine 5 mg per chew), so effects may be subtle.
- No melatonin, so not aimed at sleep-cycle support.
- Best seen as light situational support, not a treatment.
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
Does Pet Naturals Calming have melatonin?
No. It lists thiamine, a colostrum calming complex, and L-theanine, with no melatonin.
Are the doses strong?
They are on the modest side — for example, 5 mg L-theanine per chew — which suits mild situational stress rather than significant anxiety.
Is it good for sleep?
It is not designed for sleep, since it contains no melatonin. A melatonin product is the sleep-cycle tool.
