Sometimes, my innocent comments or advice, make me very, very sorry that I ever brought the subject up.
Me: I wonder if anyone has suggested that you get your dog neutered. He is cryptorchid, which means that one of his testicles hasn't descended. It's not healthy for him.
Client: I might want to breed him.
Me: Dogs that are cryptorchid shouldn't be bred, as it can be a genetic problem.
Client: Oh, no, it's fine. My son has the same problem and he has 3 kids.
