This skin disease is frequently seen in dogs during the hot humid weather. Lesions are the result of self-mutilation from excessive chewing, biting, and licking of the skin. The cause of the problem is often due to an underlying skin allergy (usually a flea problem).

Hot spots are seen as hairless, red, inflamed areas with well-defined margins. Lesions often begin as small patches and increase significantly within a short period of time. These self-inflicted skin wounds ooze a pinkish fluid that causes the surrounding hair to mat.

Hot spots are generally seen on the lower back and the thighs. Even though German shepherds, golden retrievers, St. Bernards, and collies appear to be predisposed, they can occur on any dog.

Hot spots can sometimes lead to a secondary bacterial infection (pyoderma). They are often quite painful for the dog. A normally submissive dog may bite an owner who touches the inflamed skin lesion.

Veterinary care is required for treatment of hot spots. Anesthesia or sedation is often necessary for clipping and thoroughly cleaning the area. Anti-inflammatory medication is generally dispensed.
