Whistle 3 Dog & Cat GPS Tracker & Activity Monitor
Thankfully I have not had to put it to the test but it was easy to set up. It will only work if there is wifi so places like my cabin in the woods may not work. I did track while he was on a walk and was impressed with the level of detail given.
We bought this when we adopted a blind pit mix who escaped transport and was on the run for a week. However, we ran into several problems and Whistle's tech support was unable to resolve the issue even after several hours over several days working with them. Eventually, a new Whistle 3 was sent. This Whisle works great and we had no hiccups setting it up. It sends a text message and email if she goes too far from our WiFi and tracks reliably when we tested it out. It gives me piece of mind that should she escape we have a way to track her.
