Our recommendation
Choose the Petcube for live GPS, escape alerts, and wellness monitoring at a lower hardware cost. Choose the Fi Series 3+ for the longest battery life and an integrated collar that cannot be lost.
Wellness extras vs endurance
The Petcube adds wellness monitoring and 24/7 vet chat on top of live tracking, at a much lower hardware price. The Fi tracks activity and sleep too, but its standout is battery: weeks to months against the Petcube's up to 30 days in power-save mode. Decide whether wellness extras and price or charging freedom matter more to your routine.
Form factor
The Fi builds everything into the collar, so there is nothing to attach, lose, or forget. The Petcube is a small module that mounts on your own collar, which allows collar choice but adds a unit that can be forgotten after charging. Active brush-busting dogs suit the Fi's integration.
Extras
The Petcube's LED light, buzzer, and glow-in-the-dark case aid evening searches, small but genuinely useful features. The Fi counters with the most refined escape-alert experience and base charging. Both are waterproof (Fi IP68, Petcube IP67) and both need subscriptions.
Choose Petcube GPS Tracker for Dogs if…
- Wellness monitoring and 24/7 vet chat appeal to you
- You want full GPS features at a low hardware price
- A light and buzzer for evening searches sound useful
Choose Fi Smart Dog Collar Series 3+ if…
- Longest possible battery life is the priority
- You want the tracker integrated into the collar
- Your dog is an escape artist who must always be tracked
