Pet owners have gone a little nuts in terms of what they’re willing to buy for their pooches. For example, there is now a waterproof, GPS-enabled cell phone for dogs. It tells you where you dog is and allows you to talk to your dog while he’s out in the yard or while you’re at work and the dog is at home. There is also a dog treadmill and pet pedometer, which keep your pet in shape. One company created a PDA for pets. For what else – keeping track of your dog’s schedule and his or her shots. There is even a site, dogster.com, which is like a MySpace.com site for dogs. Yikes. Is it possible that people have too much money?
