How Does a Hot Spot Occur on a Dog?
- Like humans, dogs are susceptible to skin infections. One of the most common types of these conditions is known as pyotraumatic dermatitis or, in layman's terms, a hot spot. Typically, a hot spot starts when an area of the dog's skin grows irritated and inflamed. You'll probably notice red skin and the area may feel rough or scaly. Unfortunately, due to a dog's tendency to bite and scratch the infected area, the condition can spread quickly. In just a few hours, one small patch can turn into a rash covering most of the dog's body. Hair loss may occur, your dog may develop an unpleasant odor and the spots may fill with pus that, if ruptured, will only further spread the infection. Plus, because they're most commonly found on areas that your dog can easily reach, such as the legs, feet, flanks and rump, the condition will more than likely spread to multiple locations.
- A hot spot occurs when moisture becomes trapped by the dog's skin. Unfortunately, there are many things that can cause this to happen--allergies, infected anal sacs, fleas, injuries and even poor grooming habits are just a few examples. In addition, some breeds--especially those with thick coats--are by nature prone to the condition. Dogs that live in warm, humid climates are also more likely to suffer from hot spots.
- Fortunately, there are a few ways to keep your dog from developing hot spots. First, make sure your pet is properly protected from fleas, as one little flea bite can turn into several painful hot spots. It's also important to groom your dog regularly to prevent mats and snarls from developing. If you think your dog's hot spots may be caused by an allergic reaction, keep an eye out for any triggers than may be causing the reaction--some common causes for allergies in dogs include food, dust and pollen. Once a hot spot develops, it's important to treat the area immediately. Due to the pain and itchiness around the area, this can be quite difficult -- some dogs may even growl or snap if you merely touch the area. If possible, however, shave and clean the area surrounding the hot spot and then apply a hydrocortisone lotion to the area. You may also want to purchase an Elizabethan Collar (also known as a No Lick or E Collar) to prevent your dog from picking at the area. If the condition does not improve within 2 to 3 days, schedule an appointment with your veterinarian, as antibiotics and stronger medicine may be needed.
