Say hello to Polly, a 13-week-old miniature chihuahua/toy Yorkie mix. She likes to explore the park, chase her tail and play with balls, even if they are too big for her to carry in her mouth. Polly is learning to follow her owner and to listen for commands. At the Daily Puppy, the name says it all. We love puppies of all shapes, sizes, and colors and need a regular dose of cuteness. In this video series for eHow Pets, we're putting puppy pictures in motion.
