Is your dog excessively licking and chewing a red area on his skin? He could have a hot spot, which usually requires vet-prescribed medication and a lot of care at home to heal.

How do you know if your dog has a hot spot? How are hot spots treated? We’ll arm you with all the information you’ll need to help you relieve your pup’s pesky skin irritation.

What Are Hot Spots On Dogs?

A hot spot, also known as acute moist dermatitis, is an area of the skin that’s become inflamed and infected. At first, a hot spot appears as a small red area that looks like an insect bite. But they quickly worsen and spread, appearing as a large, moist, oozing and red or bright pink area.

Hot spots are very painful and itchy, so dogs continually lick and chew the area, which further worsens the condition. You may also notice hair loss in the area. Hot spots can occur anywhere on a dog’s body but are most common on the head, limbs and hips. Hot spots are also more likely to develop in warm weather and high humidity.

What Causes Hot Spots?

Anything that causes your dog to feel itchy can turn into a hot spot. Because of the continual licking and chewing, the skin becomes damaged and develops a bacterial infection. Some common triggers for hot spots include:

  • Flea and mite allergies
  • Insect bites or bee stings
  • Allergies to food or environmental factors (grasses, trees, weeds, etc.)
  • Skin wounds
  • Ear infections
  • Poor grooming
  • Boredom or stress (resulting in excessive licking)
  • Moisture trapped in the fur from bathing or swimming
  • Infected or impacted anal glands
  • Orthopedic problems, e.g., dogs with arthritis tend to lie down on the same area much of the time which can create abrasions over pressure points, like hips or ankles

If you suspect your dog has a hot spot, it’s a good idea to consult your vet for proper treatment and to help identify the underlying cause. Treatment usually involves the following steps.

  1. Clip the hair around the hot spot
  2. Clean the area with an antiseptic solution, such a chlorhexidine spray, or medicated wipes
  3. Administer a vet-prescribed oral or topical antibiotic to treat bacterial infections
  4. Administer a vet-prescribed oral or topical steroid to control itching and inflammation
  5. Apply an Elizabethan collar (aka a cone) to prevent licking and chewing

Your vet will give you instructions on how often to clean the area and give your pup the appropriate medications. As long as you follow your vet’s home treatment regimen, most hot spots quickly improve within 3-7 days.

Preventing Hot Spots

Flea control and proper bathing and grooming may be your best bets against future hot spots. However, many of the conditions that trigger hot spots are chronic problems, like skin allergies and ear infections.

So it’s important to identify and manage the underlying cause to prevent recurring hot spots and skin problems.

If you suspect your dog’s recurring hot spots could be due to allergies, contact your vet to discuss your dog’s symptoms. You can also help identify your dog’s specific sensitivities to food and environmental factors through an at-home dog allergy test, like the EasyDNA Dog Allergy Test. Learn more in our dog allergy test kit reviews.
