Hot Spots in Dogs
Acute Moist Dermatitis (often called Hot Spots) are bacterial infections that form underneath the fur. They are often red, raw, irritated and very itchy. Hot spots are an extremely common condition, particularly for dogs in warm and humid weather. In this article, we will examine the nature, causes, and treatment of hot spots.
Hot spots are itchy, red, moist lesions under the skin which result from licking or scratching. They can manifest in a single area – often very large in size – or as several lesions on different parts of the body. A hot spot develops when the P.H. of the skin changes, causing skin infection and the resulting itch-scratch cycle. In other words, moisture or humidity forms under the skin, which in turn causes a favorable environment for bacteria. This bacterial infection is very itchy and uncomfortable for your dog, which leads to your dog scratching. However, this reaction only makes the problem worse. Scratching leads to more infection and more itching, which leads to even more scratching, as the infected area(s) grow larger and redder.
So how exactly does this vicious cycle start, and how can we prevent them? There are many underlying causes for hot spots. These include allergies, biting or itching from fleas, clipper burns from grooming, or and humidity or moisture under the fur. Identifying the cause of the hot spot is the key to preventing them from forming in the future. If a hot spot is caused by an underlying allergic condition, addressing that allergy will help prevent future occurrences.
Though it’s important to identify the cause of hot spots for preventative purposes, the actual treatment for hot spots is the same, regardless of their origin. Treating a hot spot flare-up centers on changing the P.H of that area, fighting the infection, and preventing licking/scratching. Here’s how your veterinarian will help address all 3:
- A member of the veterinary team will very gently clip the fur away from the lesion. This helps to allow the area to breathe and remove any excess humidity or moisture under the skin. After the lesion is clipped, a thorough cleaning will be performed with an antibacterial surgical scrub.
- The area is dried and allowed to air out. An E-collar is critical to help prevent your pet from licking and if needed, a soft T-shirt can be added to help protect from scratching. This way, when your pet goes to scratch the area, they will instead hit the hanging portion of the T-shirt.
- Antibiotics are an important part of treating hot spots to help rid the resulting infection on the skin. Your veterinarian will help choose the right antibiotic for your pet.
- Depending on the particular case, your veterinarian may recommend pain or itch relief medication to help your pet feel more comfortable during the healing process.
