Mollie is a 4-year old Cocker Mutt. She should have been a circus dog. She can do any trick you can dream up, as long as you have a treat in your hand. If your hand is empty, she's too smart to fall for it. She's a medium sized dog, weighing 34 pounds. She's still got her "I'm a cute puppy" face, and believe me, she knows how to use it. Yep.
