Hot Spots
A hot spot is a common term used to describe moist dermatitis. Most owners of long-haired dogs are familiar with hot spots.
The actual cause of a hot spot is unknown, but there appears to be an allergic component. Most patients that have atopy or food allergies are predisposed to developing hot spots.
The sudden appearance of a very red, moist area on the skin is very typical of hot spots. The hair is matted, wet, and discharge from the wound is sometimes abundant. The pet may chew and scratch aggressively at the area, but some animals appear unaware they have developed moist dermatitis. The most common areas for hot spots are the face, at the base of the ears, or on the trunk.
The hair overlying the wound must be clipped to allow aeration and cleaning. A steroid injection is very helpful in decreasing the pet’s itchiness and discomfort. Topical antibiotic therapy may be attempted, but most hot spots need oral antibiotics to truly fight the infection. Treatment of an underlying allergy may help in preventing future hot spots.
