This beautiful sensor monitors your dog’s daily activity and sleep and turns it into BarkPoints, so you can track progress. It’s a new way to keep your dog (and you!) healthy, explain changes in behavior, and make better decisions with your vet. It is only 8 grams and fits dogs of ANY size. Really. It comes in 5 different colors so you can match your dog’s waggin’ personality. Plus it’s IPX7 compliant (waterproof up to 1 meter for up to 30 minutes).
