Fi Series 3 Smart Dog Collar

The problem

Most GPS trackers attach to an existing collar, which means two items to check and two things that can fail. Dogs that regularly escape or go off-lead in open country need a tracker that is always on and hard to forget. If your dog stays in a small urban garden and rarely bolts, a simpler and cheaper option works just as well.

What tends to help

The Fi Series 3 is a collar with GPS built in — no separate clip-on unit to lose. It pairs with a phone app for live tracking, escape alerts, and daily step count. Battery lasts up to three months on the base tracking mode.

A straight answer: Requires a monthly subscription for live GPS. Without it, the collar stores steps but does not track location. Check Fi's current UK availability before buying.

Common questions

Does the Fi collar work in the UK?

Fi primarily uses LTE-M networks. Coverage varies by region — check Fi's coverage map for your specific area before purchasing.

How is the Fi collar different from a Tractive tracker?

Tractive is a clip-on attachment you add to any collar. Fi replaces the collar entirely. Fi also tracks daily activity; Tractive focuses primarily on location.
