There is no single “best” melatonin for every dog in Australia — the sensible choice comes down to transparent labelling, no xylitol, a format your dog accepts, and your vet’s advice. Melatonin calming supplements for dogs are sold over the counter here, so judge them on what you can verify, not on marketing.
How to choose in Australia
Prefer products that disclose each active by amount rather than hiding melatonin in a proprietary blend, reject anything with xylitol, and match the serving unit when comparing. Our full, same-unit comparison — chews, tablets and liquids — is in the best melatonin comparison.
