The Most High-Tech Gadgets . . . For Pets

Tagg GPS Plus ($100 to preorder, available March 2015) includes two months of GPS location services and costs $8 per month after that. It covers nationwide (continental US) tracking and includes an ambient temperature sensor so you can measure if your pup is too hot or too cold if they get lost. An activity tracker built in means that this pet wearable is an all-in-one type of gadget.
