This little guy is some kind of Chihuahua mix and was a throwaway headed to the shelter when a friend of a friend asked if we could take him in. He's the only small dog we have and is a bit of a pain! He refuses to get potty trained and constantly barks at everything, which gets the bigger dogs worked up too. We can understand his constant nervousness since he is basically snack-sized compared to everyone else. He is a sleeping buddy to my two boys, and they adore him.
