No question about it, this is pretty rare. Lizbud, you are right, this seems common in boxers. Phred sent me a wonderfully informative email with links, descritive terms, contacts, etc., that really helped me understand things. Dad has boxers, but, he wasn't familar with this condition. It does happen as doggies age, but, that is more excessive gum growth, rather than bone formation.

I had done some research, though it was not anywhere near as productive as Phreds....and had emailed some vets around the world, pleaing for information. I have heard from two of them. One has a patient coming in next week with what sounds like similar information. He asked that my vet send the films and biopsy results to him, which I will do. If I can help anyone, I will.
The other vet had nothing but the highest accolades for my vet- Dr Auvil. Dr. Auvil is one of the founding fathers of Vet Dentistry, and 'knows his stuff'. Dr. Auvil is consulting with another specialist next week..and Binx has an appointment. Apparently, this vet sees patients all over the world, and together, the two of them will develop a treatment plan for Binxy.

What a "coincidence" that first, I find Binx, next, dad knows of this specialist that JUST spoke at their doggie club, that this specialist who only sees patients two mornings a week, has time to see Binx, and then, that the following week, he is consulting with another top tooth vet, and Binx gets an appointment. Coincidence, right?
