"The 2-3 month battery is the reason I switched from Tractive — I forgot to charge the Tractive twice and my dog got loose both times. Haven't had that problem once with Fi."

"The behavior monitoring is surprisingly insightful — I caught that my dog was scratching excessively at night before I'd noticed it myself. Vet found a skin condition early because of it."

"Fi is worth it for the battery life alone — 3 months between charges means it's always on and I never worry about it dying when I need it."

US-based LTE network — coverage in rural Canada is significantly reduced
Fi uses LTE-M/NB-IoT networks; coverage in Canadian rural areas, northern regions, and many provinces outside major urban corridors is limited; GPS tracking may not function in areas where dogs are most likely to be off-leash.

The Fi collar requires an active plan ($9.99–12.99 USD/month) for GPS and LTE tracking; without it the collar tracks steps only via the phone's Bluetooth proximity.

Fi's modular band system has a limited size range; dogs with thick necks relative to their body size, and breeds with unusual neck-to-head proportions, may not find a secure fit.
Source: r/dogs, Amazon CA reviewsThe Fi Series 3 is for Canadian dog owners who prioritize battery life, health monitoring, and daily convenience over maximum real-time tracking precision. The 2-3 month battery and comprehensive AI behavior detection make it the most practical GPS collar for everyday use. If your dog is an escape artist who needs second-by-second live tracking, Tractive's faster update frequency is the better tool — but for most Canadian dog owners who want GPS peace of mind without weekly charging, Fi is the clear pick.
