Hot Spots in Dogs: Why They Often Flare Up in Summer

Warm weather, swimming, allergies, and moisture can make summer a common season for skin irritation in dogs. One issue owners may notice is a “hot spot,” also known as acute moist dermatitis. At Lonsdale Place Veterinary Clinic, we see how quickly these irritated skin patches can become uncomfortable for pets.

What Is a Hot Spot?

A hot spot is an area of inflamed, moist, itchy, and often painful skin. It may appear suddenly and can grow quickly if a dog continues licking, scratching, or chewing the area. Hot spots are more common in dogs with thick coats, long hair, allergies, ear problems, or skin folds.

Why Summer Can Make Hot Spots Worse

Summer activities can increase moisture against the skin. Swimming, bathing, humidity, and damp fur can create an environment where irritation develops. Allergies, insect bites, fleas, mats in the coat, and ear infections can also trigger scratching or licking, which may lead to a hot spot.

Dogs with dense coats should be dried thoroughly after swimming or bathing. Regular brushing can help prevent mats and allow owners to notice skin changes earlier.

Signs Owners May Notice

A hot spot may look red, wet, raw, sticky, or scabbed. Your dog may lick, chew, scratch, or seem painful when the area is touched. Some hot spots have an odour or discharge. Because they can worsen quickly, it is best to have them assessed instead of waiting several days.

Why Veterinary Care Helps

Treatment depends on the severity and underlying cause. A veterinarian may need to clip and clean the area, treat infection or inflammation, manage pain or itch, and look for triggers such as allergies, parasites, or ear disease. Treating only the surface wound without addressing the cause can lead to repeated flare-ups.

Hot spots can be uncomfortable and can spread quickly, especially during warm, active summer months. Keeping your dog clean, dry, brushed, and protected from parasites can reduce risk.
