Cell phone for dogs

The phone will allow users to call their dogs in case the dog gets away and also includes a GPS tracking device if the dog doesn't respond to the call. In addition, the PetCell will feature GeoFence, which will alert owners whenever their dogs wander outside a prescribed area. Will the PetCell actually prove useful to dog owners or is it just another cheap gimmick?' "
