FernTrack GPS Collar

Know where your dog is — every minute of every day.

The FernTrack GPS Collar uses real-time 4G location tracking with geofence alerts so you get a notification the second your dog steps outside your yard. The clip-on tracker fits any standard collar, syncs to your phone via the free Fernpaw companion app, and stays charged for up to 7 days on standby.

A note on monthly service

The cellular service runs about $3 to $9 per month through the device's built-in carrier — you'll set this up in the app the first time you pair it. We don't take a cut of this fee.
