Winner: PETFON
We can say that both of these dog GPS trackers have their ups and downs, but for us, we can clearly see which one is the better device. Findster Duo + is already great on its own as it can also track three dogs at a time as much as PetFON can also do, and another good point for them is the battery strength is very long-lasting. However, PetFON has way better reviews and overall feedback and it’s also a dog GPS tracker does not require monthly fees.
