ABOUT LEO Meet adorable Leo! Leo is a 3yr old yorkie-chihuahua mix, weighing just 5.6lbs. Sweet little Leo is such an easy-going boy. He's happy to relax on your lap or in a doggie bed nearby. Leo has good leash manners, but of course he also loves to be carried. Leo isn't one to really romp or wrestle with other dogs, but he seems to enjoy the company of other dogs. This quiet fella quickly wins your heart with his frizzy fur and gentle kisses!
