What Are Hot Spots on Dogs?

Hot spots are formerly known as acute moist dermatitis. These are red, painful areas of infected skin. They are sometimes raised and appear to be irritated. Hot spots can appear quickly and usually come with some hair loss. They can grow larger in just a few days. 

Dogs can get hot spots on any area of the body but are most commonly found on the hips, neck, limbs, or face. The appearance and the size of the lesions can slightly vary in location, but they mostly will look similar regardless of where the hot spots are located. 

Hot spots on dogs can heal quickly and be relatively minor, but they do have the potential to become a serious issue, such as deep skin ulcerations or even widespread infection.


What Do Dog Hot Spots Look Like?

Hot Spots on Dogs are typically roundish red spots on your dog's skin. The spots will get bigger and more irritated if your dog licks them. 

Hot spots on dogs can range in size. They are usually inflamed, raw and red. You may notice intermittent bleeding at the spot, but that doesn’t always occur. The area will become painful and moist. It typically will spread due to a dog scratching, licking, or chewing around the area. 

Hot spots on dogs do have a unique look that is typically different from other skin conditions, including mange and ringworm, because the skin is very inflamed and moist.


What Causes Hot Spots on Dogs?


Treating hot spots isn't too complicated when you know what is causing them. Treating both the wound and the cause at the same time will help the spots heal faster and prevent them from coming back. 

There are several common conditions that can cause dog hot spots. These include: 

1. Food allergies

How you treat allergies will depend on the type. You may have to change up your dog’s food. You can document which foods help and which cause issues. Reach out to your veterinarian if necessary to help determine the best way to help your dog. 

2. Flea allergies

Your dog may have adverse reactions to fleas. It’s critical to make sure your dog doesn’t have fleas and prevent them from occurring.

3. Seasonal allergies. 

Yup, dogs get them, too. Seasonal issues are less common than food allergies, so it's important to rule those out first for proper treatment.  Dogs may have seasonal allergies, including grass, pollen, mould, hay, fungi, and pests. You can help keep them healthy and comfortable with diet changes, digestion support, liver detox, and topical treatments.

4. Ear Infections 

The yeast or bacteria from the ear canal can actually be so irritating that the dog scratches at it, which can create painful hot spots behind the ear, on the neck, or on the ear flap. Treating ear infections right away can help prevent secondary hot spots from occurring and keep your dog healthy and comfortable. 

5. Moisture from Swimming 

Excessive moisture from swimming is another common cause of hot spots on dogs. To prevent hot spots from occurring, make sure to let your dog thoroughly dry off, so his coat and skin stay safe and healthy. 

6. Poor Grooming

Dogs that have long or unkempt hair can get tangles, which dogs then may bite at. This 
can cause open wounds and matted fur, which sets up the perfect environment for a hot 
Spot. Keeping your dog properly cleaned, brushed, or groomed can help reduce hot spot potential. 


How to Treat a Hot Spot on a Dog


Many times, hot spots can be treated at home. However, it is very important to understand the cause of the dog hot spot. The cause should always be identified in order to prevent further hot spots from happening, as well as treat any underlying conditions. 

To determine the underlying cause and for overly infected hot spots on dogs, a trip to the vet is necessary. 

It’s even more urgent if the affected area is:

  • Increasing in size
  • Consistently bleeding at the site of the hot spot. 
  • Coloured discharge
  • You cannot keep your dog from scratching or licking the hot spot.

You should also seek veterinary attention sooner if you cannot keep your pet from licking/scratching it. Tools like a dog cone could help to prevent access to the area, but this may not work for all dogs. 

How Does the Vet Treat Hot Spots in Dogs 

If your dog hasn’t had a hot spot before, you may be curious about what the veterinarian will do. Depending on the severity of the hot spot, most vets will treat the area with an e-collar, give your pup anti-itch medication, and prescribe oral antibiotics. 

The veterinarian may run tests or determine the underlying causes of the hot spot, which may require additional treatments or medication. Most commonly, these include allergy medication, flea prevention, ear medications, and more. 

It’s important to get your pet veterinary care as soon as possible, so you can prevent further infection.

Home Remedies for Hot Spots on Dogs 

If you aren’t able to get to the vet right away, there are a few things you can do at home to help heal hot spots.

Follow these steps to promote the healing of the hot spot:

  1. If necessary, use dog hair clippers to trim the fur around the hot spot. This allows the hot spot and affected areas to get air, which can prevent excess moisture that can hinder healing. Make sure not to use scissors- it may be likely that you will injure your dog since you can’t necessarily see how big the hot spot is under the hair.
  2. Clean the skin with a mild shampoo or water-based antibiotic.
  3. Apply a veterinary-recommended hot spot treatment spray. 
  4. Keep an eye on the area to see signs of healing or to determine if additional treatment is necessary.
