Hey Fido! Get the Phone!

Check it out -- here's a concept product that gives a unique twist to the action of "calling your dog."

It's a cell phone and GPS unit on a collar, with its own private number. Using caller ID, it automatically picks up when an approved number calls, allowing you to speak to your dog from wherever you are. And with the GPS service enabled, you'll even be able to yell at them when they've wandered too far from home.
