In breeds with pendulous lips, folds on the lower lip that make contact with the upper teeth may become inflamed and infected. This tends to occur in St. Bernards, Cocker Spaniels, setters and some scenthounds. The lower skin folds often form pockets with the overlying skin folds of the upper lips, which trap food and saliva, creating a constantly wet environment that favors bacte- rial growth. When the folds are flattened, a raw surface is visible. The foul odor is often the reason for seeking medical attention.
Treatment: Treat as described for Skin Fold Pyoderma.
