What are “Hot Spots” in Dogs?

The dog’s skin is the largest organ of the body, yet there is a very restricted number of ways in which it responds to trauma. “Hot Spots” or acute moist dermatitis are locations on the dog’s skin due to your dog’s itching, biting and scratching and may often arise quite suddenly. These places may become very large and may develop just about anywhere on the dog. I see it sometimes in the spring time once the temperatures are warmer as well as the humidity is high. The dogs with the thick undercoat, such as Labs, golden retrievers and rottweilers are susceptible to getting these spots on their face and neck. Typically, spots located at the base of the tail are very likely resulting from fleas simply because fleas choose to congregate in these areas. Quite a few dogs happen to be so hypersensitive to fleas, the bite of one flea is sufficient to induce the dog to itch all over. Almost any injury can begin the process which the dog then exacerbates by continual chewing and licking which in turn results in a vicious cycle and will cause the hot spot to spread.

The dog normally has bacteria that lives on their skin and so long as the skin is healthy, the microorganisms almost never result in any issues. However when something occurs, such as a fleabite, cut or allergies, the dog begins to lick, bite, chew and scratch which in turn disrupts the defensive layer of the skin. As soon as that takes place, the bacteria on the skin, as well as the germs in the mouth, set up housekeeping in the skin. This creates a swiftly spreading infection which may be quite painful. The area on the skin is red, raw and seems moist because the wound oozes serum and pus. The hair then mats down over the wound and the infection then spreads beneath the hair.

A visit to the veterinarian is usually called for. In many cases the fur must be clipped off to stop the spread of the infection. Sometimes, these hot spots are so painful, the dog may need to be sedated in order to have the region cleansed and shaved. Antibiotics are prescribed to take care of the infection and follow-up antibiotics are sent home. Sprays, ointments and medicated shampoos can also be prescribed to continue treatment at home.. For some dogs, a special collar may be used that can help deter the dog from chewing at the places.

The particular underlying reason for the insult should likewise be tackled. If fleas can be found, then year round flea control may be prescribed.(over-the-counter flea control is not recommended) Pollen, food, and other allergens can also precipitate an attack. Sometimes specific diets with essential fatty acids and a novel protein source for example salmon, lamb or venison may be recommended to help heal the skin. Blood and skin tests can be preformed to help discover what the dog is allergic to and special allergy injections or prescription diets is often given.

Check your dog daily for itchy spots and use flea control suggested by your veterinarian year round to help avert hot spots as a result of flea allergies. Daily grooming and brushing can keep mats from developing. If your dog is itching continuously, take him to the veterinarian to handle the itching before the infection can progress.
