At FitBark, we think of dog and human health as one. We couldn’t imagine a world where we push our bodies and watch?our diets to get healthy, and leave the pets we love on a path to medical crisis - with minimal?exercise and unrestricted access to food. That's why we are entirely dedicated to getting you and your pet healthy together. And making it fun!


And you know who shares our mission? Animal Planet. With 54% of US dogs affected, obesity is the single largest epidemic facing our pets today. Watch how the FitBark platform helps get pets healthy in Animal Planet's new show “My Big Fat Pet Makeover.” And guess what? Clipping a FitBark to a pet's collar helps the humans in the show just as much as it benefits their pets!

Our friends at the Mayo Clinic also think of human and pet health as one. Learn about how they used the FitBark in a series of One Health studies to assess whether dogs disrupt human sleep. (Spoiler alert: For the most part, they don’t!)

So what is FitBark? It’s a small, colorful device that you attach to your dog’s collar. It monitors activity levels, quality of sleep, distance traveled, calories burned, and overall health and behavior 24/7.


We are now proud to introduce you to our latest addition to the family: the FitBark 2. The biggest upgrade with the FitBark 2 is a battery life up to 3.5 dog years (6 months), so you can worry less about recharging and more about bonding with your pup. It fits dogs of any size, and it loves the water as much as your dog does!

You can link it to your Fitbit, Apple Healthkit or Google Fit device (or just use your iOS or Android phone to track your steps) and chart progress side-by-side. Talk about motivation!

We built the FitBark 2 in collaboration with 45+ veterinary schools and research institutions that have been using our platform in clinical settings to address mobility issues, skin diseases, nutrition, cognition, vision and a wide variety of medical conditions.

A drop in the FitBark Health Index helps you catch early signs of discomfort or disease.

FitBark allows you to share your dog's information with your trainer or veterinarian to monitor orthopedic rehabilitation, osteoarthritis or changes in mobility.

Your pet's FitBark Sleep Score can help you track the development of skin conditions such as atopic dermatitis.

A quick look at activity levels after you leave home provides valuable clues about your dog's anxiety levels and how he or she is doing while you're away.

Do FitBark devices control barking?

Not really. FitBark devices are activity and sleep monitors. On a side note, plenty of exercise helps eliminate hyperactive, destructive, unruly and attention seeking behaviors that may or may not include excessive barking. In addition, if your dog tends to be?anxious when left alone, FitBark helps you monitor how his activity and anxiety levels change during the hours after the separation. You can learn?more here.

Is FitBark 2 waterproof?

Yes. FitBark 2’s waterproof specification is IPX67 (can be submerged up to 1 meter for up to 30 minutes). After a day of fun playing in the water, remove the cover to make sure any water on the charging pins fully dries before putting it back on the FitBark 2.

Can I use FitBark devices on a harness?

FitBark devices are designed to be fixed?on a dog collar. Wearing your FitBark device on a harness may?reduce its activity and sleep tracking accuracy.

Can I use one FitBark device on multiple dogs?

As a regular dog owner, we don't recommend this as?you?won’t get much value out of the platform if you don’t monitor your dog’s health, sleep and behavior 24/7. As a pet healthcare professional, we make it possible to cycle one FitBark device on multiple dogs if you're running a clinical study or are temporarily lending a unit to a client. Please make sure to create new dog profiles for each dog and?"Assign New FitBark" when you want to associate a FitBark unit to an existing dog profile.

Can a cat wear a FitBark device? What about other animals?

Yes, but?you won’t find much in terms of comparative norms and baselines. Please choose an animal within?the "not a dog" list when you setup your FitBark device on a cat, bunny, pig, sheep, chicken, penguin, falcon, zebra or any other animal or human.
