Bacterial and fungal infections can have your dog feeling itchy, with skin that appears flaky, crusty or moist. Redness, inflammation and odor may also be a problem. The most common clinical signs of yeast dermatitis include: Thickened skin or “elephant skin” Flaky, crusty or scaly skin Redness and itchiness Musty odor. The most common clinical signs of staph infection are: Excessive itching, licking or chewing Eye, ears, skin or respiratory system infections Patchy fur with peeling, crusty skin, or moist skin Inflamed or red skin Pain Pus-filled lesions on the skin. Skin can become irritated when a dog excessively scratches, chews or licks.

Symptoms of skin infections include redness, itching, hair loss, bumps, pustules, and spots. It’s important to check common areas like the paws, groins and armpits. Skinfolds are particularly prone to skin infections, and dogs with heavy pendulous ears are very susceptible to infections. These infections happen because long, heavy ears can promote bacterial growth. Your vet may be able to diagnose by looking.

The most common clinical signs associated with pyoderma are papules or pustules that form on the skin. These lesions often look similar to pimples in humans. They are most often red and raised, with a white pus-filled center. Other signs include circular crusts, dry or flaky patches of skin, hair loss, and itching. In short-haired breeds, the coat may appear to protrude or stick up in areas, mimicking hives, or it may appear moth-eaten because of patchy hair loss. Some cases may involve a moist layer on the skin or a musty odor, particularly in between toes or skin folds. Puppies often develop puppy pyoderma in thin-haired areas such as the groin and underarms. Skin folds may also be affected, creating a warm, humid environment. The skin folds allow the surface of the two adjacent areas to lie in close contact, creating an environment where the normal skin bacteria then multiply, creating an infection in the fold.
