The verdict
Buy the Tractive GPS Dog 4 if you want the better overall package — it leads the PetScore 87 to 84 and is the stronger fit for escape-artist dogs.
Buy the Fi Series 3 if its strengths match your household — it's built for long-battery LTE collar for dogs. Note that our pick is also the cheaper one to own over three years ($374 vs $635), which makes this one less of a dilemma than the stickers suggest. Either way, the receipts are on each device's true-cost page.
