A new app, Finding Rover, aims to reunite owners with their lost dogs and to support the work of animal shelters.
Simply register (for free), upload a photo of your dog, and go. When someone finds your dog, they send in a photo of the dog’s face to be scanned and matched through the database.
Of course, micro-chipping is also a good way to identify your dog in the event it gets lost. Micro-chipping is now mandatory in New Zealand.

Interesting, although a lot of dogs of the same breed would look alike in the database. I would like to see GPS technology used in collars to allow owners to track their dogs when they get away!
