Roo's mom says: Roo is a new addition to our family, born March 18, 2006. He weighs in at three-and-a-half pounds, compared to his seven-pound stepbrother Chihuahua, Zeus. Roo was accepted with open paws and was taken right under Zeusâ€™s wing. They give each other regular baths and make sure they each get plenty of exercise. The two of them are inseparable. I adopted Roo from a private breeder who chose his name because when he runs, he hops. I thought it was the perfect name for him. Watching him run and play is the funniest thing to witness. Sometimes I think I have a â€œTiggerâ€ in the house rather than a puppy when he bounces from here to there and back again. He learned the hard way about bouncing too much and broke his little leg. Overall, he is a bundle of joy and I couldn't imagine a day without him.
