Dealing with Hot Spots in Dogs
Acute moist dermatitis, also known as hot spots, are localized, moist, reddened bacterial infections of the skin of dogs. A hot spot starts because something irritates the skin. The body's response is either to itch or become inflamed. The itching then causes the dog to lick or chew the area, which further damages the skin, and creates a cycle of itching, scratching and chewing.
Hot spots can be caused by anything that irritates the skin and initiates an itch-scratch cycle, but the most common irritants are fleas. Other causes are allergies (flea, inhalant, food), parasitic disease (sarcoptic and demodectic mange), anal gland disease, poor grooming, tick and mosquito bites, burrs, and summer heat. They are most common in long-haired and heavy-coated breeds, and are more prevalent during the summer months.
