Well... My opinion is the third and I'm going to do what they said. I was on the fence about it. They said it's a genetic defect and could cause cancer so I'm going to. He'll just have to be a one of a kind doggie. They want me to do the pinch because he won't cooperate with them. His problem is he is too smart and knows what they are up to. 😉Why did you need a third opinion?
