GENERAL CONDITIONS

Acute Moist Dermatitis("hot spots", pyotraumatic dermatitis, moist eczema) is produced by self-inflicted trauma as the patient attempts to alleviate some pain or itch. Most cases are complications of flea allergy dermatitis, although allergic skin diseases, other skin parasites, anal sac problems, ear infections, and musculo-skeletal disorders may be underlying causes. Once the skin is irritated, an itch-scratch cycle is initiated and the intense trauma produces sever lesions in a few hours. Dogs with heavy hair coats, such as Golden and Labrador retrievers, Collies, German Shepherds, and St. Bernards are particularly predisposed to this problem. The problem is much more common in hot/humid weather, and may have something to do with lack of ventilation in the coat.

THERAPY

The lesion is very painful and will progress rapidly if appropriate therapy is not started at once. Therapy is effective if applied promptly and vigorously. Sedation or anesthesia is usually needed to allow thorough cleaning of the area. Antibiotics and anti-inflammatory agents may also be required for treatment.

PREVENTION

Unfortunately, there is no simple method of prevention and some dogs may have repeated problems. Constant attention to grooming hygiene, baths, parasite control, and periodic cleaning of the ear and anal sacs will help prevent problems. You should be especially vigilant during periods of hot, humid weather.
