Our take on the ranking
Short answer: the PawTronic Pro Series 2 ($278.99) is the best GPS dog fence without a subscription: custom shapes, six saved layouts, dogs from 7.9 lb and four alert modes. If you want the fence brand with the strongest hardware and can pay up front, the SpotOn Omni ($899) and Nova ($999) need no plan for the fence either.
No subscription usually means no live tracking. These collars store the fence and decide on their own when to cue the dog; nothing reports back to your phone over the cell network. SpotOn is the exception: its fence works with no plan, and an optional plan ($7.49 to $9.95 a month) adds tracking.
Here the cost criterion counts only what you cannot avoid paying, so optional plans are left out, and it weighs 35% of the score.
Scope: GPS fence collars whose fence works with no plan at all; optional tracking plans are left out of the cost.
