Do GPS collars work in the woods?

GPS works anywhere with sky visibility. The limiting factor is cellular coverage — LTE-M has wider rural coverage than standard LTE. Fi and Tractive both use LTE-M for better rural performance.

What size dog can wear a GPS collar?

Most GPS trackers work on dogs 10 lbs and up. AirTag with a mount works on any size. Fi's collar attachment is best for dogs 20 lbs+. Tractive clips to any existing collar.
