Did you know that only a very small percentage of lost animals – 10-15% of dogs and 2% of cats – are ever returned to their owners? If your pet strays, you need to know immediately so you can retrieve him quickly. The Tagg Pet Tracker system from Snaptracs, Inc ( a wholly-owned subsidiary of Qualcomm Inc) uses GPS to track your dog or cat and let you know immediately if he leaves his defined home area. The Tagg slides onto your pet’s collar; it’s built to withstand dirt and even water. If your pet leaves his home area, you’ll be notified on your computer or smartphone. You can locate your pet on a map just by pressing a button so you’ll know where to go pick him up. The collar attachment is intended for pets over 10 pounds. It costs $199.99 and includes a year of service. It will begin shipping in September. You can sign up at the Tagg website to be notified when the device is ready to ship.
