Vet said dog is about 5 years old. He has always had bad breath since we’ve had him. I just kind of accepted that, until last week when one of his teeth fell out and then I did a little research. By the way the tooth that fell out had lots of tartar build up. So I have no doubt that he “really!” needs his teeth cleaned. What I’m not sure about is does he really need to be castrated? I mean how many men would get a vasectomy if it involved castration? Not many would be my guess.
