Hot spots on dog skin (acute moist dermatitis or pyrotraumatic dermatitis) occur most often on dogs with long, dense coats. They are more likely to occur during hot weather that appear to happen overnight. There are a number of possible causes, including insect bites (particularly fleas), mites, allergies, poor grooming, ear infections, and anal gland disease. Flea allergy is the most common cause.

They are moist and inflamed, and the hair will fall out in that area. They are quite painful. Your dog will usually scratch, like or bite the area, irritating the skin even more. Hot spots are sometimes called “pyotraumatic dermatitis” (meaning self-caused skin inflammation) because the self-trauma is a major factor in the development of the sores. The sores can grow larger very rapidly.Diagnosis of hot spots on dog skinHot spots can mimic other skin problems, so your vet will need to examine them carefully to determine that is what they are. They may appear similar to some fungal infections, but your vet can rule those out with blood tests or by taking a swab of the affected area and examining it under a microscope.Your vet will also look for possible causes of the hot spots. For instance, if the hot spots are on the ears, then ear infection is a likely cause. A homeopathic approach to ear hot spots is available from PetAlive.com.

Treatment of hot spots on dog skinTreatment of hot spots must be aimed at healing the hot spots as well as eliminating the cause. The canine skin hot spot is treated by first clipping the hair around the lesion. This allows air to get to the inflamed skin and makes it easier to treat the wound. The spot is then cleaned and a topical treatment is applied such as Betadine or chlorhyexidine. If the wound is infected, oral antibiotics are prescribed. Oral anti-inflammatory medication may also be prescribed in severe cases.Glucocorticoids (GCC) are frequently suggested such as a hydrocortisone treatment such as Dermagard Hydrocortisone Spray The underlying cause of the hot spot must be identified and treated, or the problem will just keep coming back. Any infections will be treated with antibiotics. Fleas and mites are usually treated with topical solutions or medicated shampoos. If poor grooming is an issue, your vet can instruct you on the best way to groom your pet. An Elizabethan collar or foot bandage may be used to keep your dog from scratching the treated area.
