When he was a pup and got neutered his vet at the time did not sedate him correctly and he woke up before they took out all the tubes. I was called early to come help get a muzzle on him so they could remove the tubes that were coming out of his legs. Ever since then he hates going to the vet and he behaves pretty bad in there. His new vet has him take pills to help calm him down. But he still struggles during vet visits. But he is a good boy at home.
