Do FitBark devices have GPS?

No, or at least not yet.?At FitBark, rather than answer the question "where is my dog?" we focus on health, activity, sleep and behavior. Our goal is to better understand our dogs.?Our mission?is?to inspire a healthy lifestyle for dogs and humans.?That’s why we designed an experience that is?dynamic and has use?throughout the?day.

Note: while we continue to look at ways to introduce?new sensors in the future, for now we’re extremely proud of FitBark’s?tiny product size, form factor and battery life. Introducing a GPS sensor at this time would likely?make our product 5-7 times as bulky.

Based on our previous experience with similar components and materials, our current assessment is the following: Operating temperature: -4°F to 122°F (-20°C to 50°C) Storage temperature: -22°F to 140°F (-30°C to 60°C)

What do the FitBark 2 LEDs mean?

Under normal operating conditions, the FitBark’s LED is off. Here’s a description of what the various modes mean: FitBark powered with LED flashing (rapidly at 0.5 secs interval): the FitBark is in pairing mode and ready to be associated with any dog’s profile (if the FitBark isn’t already associated with an existing dog) FitBark powered with LED solid: battery fully charged FitBark powered with LED blinking slowly (10 seconds interval): battery is charging FitBark not powered with LED constantly blinking: error mode –> please contact us from the Support Chat in our mobile or web apps FitBark not powered with LED solid: error mode –> please contact us from the Support Chat in our mobile or web apps FitBark powered with LED completely OFF: please unplug and contact us from the Support Chat in our mobile or web apps

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. If you use a harness to?take your dog out for walks, we recommend that you keep your FitBark device on a light, soft collar that your dog can wear 24/7 and wear the harness on top of that.

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.
