When I bought Melly the Chihuahua at three months of age, my Chinese Crested Powderpuff, Mimi didn't want a thing to do with her. Things turned about two weeks later when Mimi felt some motherly instincts come in and she has never left Melly's side ever since. This was the two of them as I caught them sleeping in the dog crate one day. So cute! Best friends forever!!!
