FEATURES

GPS TRACKING

On vacation? Friend walking the dog? Instantly track your dog's location no matter where they are. Fi gives you the confidence to know they're safe from anywhere, anytime.

STOP ESCAPE ARTISTS

Designate safe zones around your home or dog's favorite places. If they leave without a trusted person, we'll alert you immediately. So if they wander anywhere, you'll be the first to know.

ACTIVITY MONITORING

Track your dog's step count daily and start streaks by achieving custom goals you set. Then see how they compare with similar dogs in the Fi community. Every step goes a long way toward keeping them happy and healthy.

AI BEHAVIOR INSIGHTS

Fi Series 3+ tracks more than just steps. Spot trends in activity, rest, scratching, licking, drinking, eating, and barking so you can stay in tune with your dog's health and habits, every day.

LOST DOG MODE

Never lose track again. If your dog goes missing, activate Lost Dog Mode to turn on rapidly refreshing live location updates until they're found.

BATTERY LIFE

With best-in-class battery, our collars lasts up to 3 months on a single charge. No other collar even comes close.
