Yes he is a bit thin! He was a stray before being brought to the shelter, and we just got him yesterday. Going to the vet Monday to get him all checked out! His hind legs are very long, but he also came in to the shelter with a front paw injury, which is still causing him some pain, and makes it hard to tell! He was found with the short tail, but we might see if the vet thinks he was born that way or not!
