Performance notes
The 6mg extra strength dose is on the higher end for melatonin-based dog chews, which fits its positioning as a sleep aid for medium and large breeds rather than a light daytime calming chew. Because it's dosed higher, it likely works faster for nighttime settling than a lower-dose daytime formula would.
What buyers say
A 4.5 star average across more than 2,000 reviews, plus around 600 units bought in the past month, points to strong, consistent satisfaction from a large base of repeat buyers.
No, this extra strength 6mg formula is specifically marketed for medium and large breed dogs, so it's not the right dose for a small breed.
Is this meant for nighttime use or daytime anxiety?
It's positioned primarily as a sleep aid to help dogs settle down at night, though melatonin can also support general anxiety relief.
Should I start with a lower dose?
Since this is an extra strength 6mg formula, it's a good idea to see how your dog responds before making it a nightly habit, and to talk to your vet if your dog is new to melatonin.
