Oh yeah, I forgot to add this to my last post but I have never heard of a vet that would not neuter a dog of any smushy face breed. I would definitely go elsewhere so you can get him fixed ASAP.
I have had several dogs de-sexed, male and female and including several shih tzu purebreds and I have never heard of such a thing.
I do breed, (not shih tzu's any more) but I have been also doing rescue, taking in all kinds of dogs for over 25 years and I know this vet is wrong (as we all do), but I would not only not listen to a vet like that, but I think I might go as far as reporting him because I think, for whatever weird reason, he just did not want to do it.
I would certainly question him as to where he got his information and ask him for proof as to why he cannot neuter a shih tzu mix or purebred. I would put his butt on the spot!
