This little Butter is just a prince. We are guessing him to be medium sized as an adult. Playful but can be calm. Crate trained and doing great with leash walking. He has also learned sit! Sweet boy with a good disposition. His silly antics will keep you cracking up. Just like any dog, Butter can use a bit more training and guidance to become a balanced adult dog. But he's on the right track.Butter adores the company of other dogs and would love one his size in his forever home.
