This brilliant bone-shaped bowtie tracks your dog's activity levels, quality of sleep, distance traveled, calories burned, and overall health from your Fitbit, Apple Watch, Health Kit, or Google Fit device. It's waterproof, fits any size of dog, and has up to a six-month battery life.
Promising review: "If I could give more than five stars I would! We use three in our dog family and absolutely love them. It’s not only the best activity tracker out there, it has a place to keep a journal along with key medical information. We’re able to graph the dogs' activity and compare it to sleep, show weight gain/loss over time, and so much more. The support within the app is beyond amazing. We’ve sent in questions at the most random times and we ALWAYS get a human response within a few minutes. If you ever need anything, the small but dedicated team is there for you when you need them." —Patrick
