Hot spots on dogs: FAQ

What is a hot spot?

A hot spot (also known as moist dermatitis) is an area of irritation that can be found anywhere on your dog’s body.

What do hot spots look like?

Hot spots on dogs look like areas of redness, hair loss or swelling. The area may be moist or produce pus, which can cause matting of hair around the area. Hot spots are most likely to appear on your dog's head, limbs or hips.

What causes hot spots on dogs?

The most common cause of hot spots on dogs is itching, scratching or licking excessively in one area. This can cause your dog's skin to break and ooze moisture.

Bacteria can stick to the open wound and moisture provides the perfect environment for the bacteria to multiply. Long hair can make a hot spot more likely, especially in hot weather.

How are hot spots treated?

Your vet will be able to advise you on the best course of action. Treatment for hot spots includes:

• using clippers to shave the hot spot and the surrounding area – this allows air to reach it
• putting an Elizabethan collar (also known as a buster collar or a cone) on your dog to stop them from irritating the area by licking, biting and scratching. Preventing ongoing trauma is vital.
• bathing the hot spot with a medicated shampoo
• applying a prescribed cream or spray
• administering a course of antibiotics (this is only occasionally prescribed)

How can hot spots be prevented?

Because itching and scratching is the most common cause of hot spots, it's important to understand why your dog is doing this in the first place. 

Itching and scratching is usually caused by ear problems, fleas, allergies or insect bites. You should contact your vet to treat allergies and prevent fleas, to reduce the risk of hot spots. Regular grooming and bathing can also help with skin and ear problems.
