Tweeting Isn’t Just for ParakeetsMost dogs lack mastery of the English language. But that doesn’t mean they don’t or can’t communicate with us. In fact, they do it every day, and we communicate back. In other words, dogs are social. So why not let them use social networks? That’s the thinking behind Puppy Tweets. The product includes a dog collar that senses motion, and it interprets that motion to figure out what your dog is doing. It then transmits that information wirelessly to your home computer, where the software sends a Twitter message, or tweet, from your dog’s Twitter feed. The software chooses from about 500 tweets based on activity. You, as well as others if you choose, can follow your dog’s Twitter feed and get messages triggered by activity all day.
