My vet told me the underbite mine have contributes to dental problems. I've had their teeth cleaned a few times, but hesitate to do it because I'm afraid to have them anethesized. I just read an article by Dr. Oz that having your dog's teeth cleaned can add years to their life, so I'm getting ready to do it again. I'm still nervous about it.
