Wonder Paws Melatonin Drops is a liquid melatonin product that also lists L-theanine (Suntheanine). It is a reasonable format for owners who want drops — but in July 2026 we could not verify the exact per-mL amounts on the retail listings we could access, and the product page copy was internally inconsistent. We report only what we could confirm.
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
| Item | What we could confirm |
|---|---|
| Actives named | Melatonin; L-theanine (Suntheanine) |
| Per-mL amounts | Not displayed on accessible 2026 listings |
| Inactives (per retailer listing) | Purified water, vegetable glycerin, natural bacon flavor, potassium sorbate |
| Format / size | Liquid drops, ~60 mL |
Strengths
- Liquid format allows finer dosing than a fixed tablet.
- Names its actives (melatonin + Suntheanine L-theanine), and L-theanine has situational dog evidence (Pike 2015).
- Simple, disclosed inactive list on the retailer listing.
Limitations
- We could not verify the exact per-mL melatonin or L-theanine amounts on accessible 2026 listings — confirm on the physical label.
- Product page copy was internally inconsistent (it referred to “chews” and cited ingredients like chamomile/L-tryptophan not matching a melatonin + L-theanine drops formula).
- Because amounts were unverified, we do not state any numeric comparison to other products.
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
How much melatonin is in Wonder Paws Drops?
We could not verify the exact per-mL amount on the listings accessible in July 2026. Check the printed label on the bottle you receive.
Is Wonder Paws a good melatonin product?
It offers a liquid format and names its actives, but the unverified amounts and inconsistent page copy mean you should confirm the label yourself before relying on it.
Does it contain xylitol?
The retailer inactive list we saw (water, glycerin, bacon flavor, potassium sorbate) did not list xylitol, but always confirm on the current physical label.
