This GPS for my dog really works well.
Purchased this device to keep track of my new Black Labrador. Live out in the mountains and we have deer, elk, moose, bears, coyotes, squirrels, hares, and other dog distractions all over the place. Using this GPS tracker keeps the pup from getting lost and me from getting worried. Gives me a pretty good location of where he roams and I can find him if he hasn't come home after a while. Really like the iPhone app as well. Easy to use and again, allows me to find the pup when he wanders away on search of adventure.
