well that's what our vet personaly told us, and some other vet's to. Tera died of jaw cancer from it, so i' not trying to be rude but i belive my vet, and beside's even if the vet is wrong, i'm not going to try to figure it out and go serching in tear's past, how tera died because it's to painful to think. Tear died from a fast growing jaw cancer, it rare but its true, I posted here to help people so they will not see there dog go threw the pain like i saw my dog go threw, she basically died right in front of my eyes
