Among some of the hot doggy doodads:
• A two-way cell phone that straps to the collar, letting you and your faithful friend have a conversation (via speakerphone). And if Rover gets lost on the way home, a Good Samaritan can simply press a button on the phone, which will then instantly call your house.
• A collar-attached camera that takes pictures at doggie level, allowing Fifi's owners to see exactly what a dog sees (which hopefully won't be another dog's rear end).
•A dog-centric PDA, which lets owners keep track of vet appointments and playdates.
