Max, he was in a lot of pain. He was hiding in different parts of the house and his tail was down, and he was howling, He went to the vet twice and finally the vet said they thought he might have stones and that he was probably stuck with his intestines. Dr. Vargas adjusted it, and boom, Max got up, walked around wagging his tail, and was perfectly fine. So I have to say he did an amazing job.
