Ever wonder what your pet is doing while you're away? Whenever you dog MOVES or BARKS, the Puppy Tweets tag detects it and sends a message to your home computer. Your computer then sends a message to you via your Twitter account. Tweets are based on movement, so when your dog's hyper you'll get a different message than if the afternoon was one big power nap. Puppy Tweets also recognizes time of day, days of the week, even holidays!
