So, your dog has dermatitis. What exactly does that mean, anyway? In fact the term is deceptively nonspecific. It only means that your dog has one of a variety of inflammatory skin diseases. Dermatitis can result from bacterial infections, sunburn, food allergies, drug reactions, nutritional deficiencies and a host of other triggers. And in each case the disease will manifest itself through intense scratching and biting at the site of irritation.
Pyotraumatic dog dermatitis, colloquially known as a hot spot, appears as a wet, red, hairless sore on a canine’s flank. Although hot spots seem to crop up suddenly, they are actually the result of a dog furiously scratching a patch of irritated skin during the night. Bacteria invade these areas of raw skin that have been broken down by the dog’s own scratching. In effect, the problem compounds itself until it is finally solved with the use of skin therapy products.
