If your dog has a short upper or
lower jaw and his teeth do not come together (like pugs, bulldogs, shih tzus, boxers, and other brachycephalic breeds), he breathes through an open mouth, or he has normal
jaws but they are tiny and the teeth are too close together (like the Maltese, Yorkie, Miniature Pinscher, and some other small breeds) daily brushing is vital to prevent tartar buildup, gingivitis, and the eventual
development of periodontal disease.
