I was wondering if anyone else had any issues with there dogs teeth? My Butterball has horrible teeth. We took him to the vet and he said it was a genetic defect and that there is nothing that can be done. He is only 1 1/2 and his teeth look really bad. I have a doggy tooth brush and we brush often, but they still seem to be getting worse. The vet says the enamel on his teeth is bad and that is causing the brown spots and decay on his teeth. Anyone else have this?
