Hot, humid weather can be tough on our pets—and one of the most common problems we see during this time is hot spots. These are painful, inflamed areas of skin that appear suddenly and can worsen quickly if not treated

What Are Hot Spots?

Hot spots, also known as acute moist dermatitis, are localised skin infections that often start with an itch. A small irritation—such as a flea bite, scratch, or moisture trapped in the coat—can cause a dog to lick, chew, or scratch the area. This self-trauma creates the perfect environment for bacteria to grow, leading to a red, weeping sore.

What to Look Out For

Keep an eye out for:

• Red, moist, or oozing patches of skin
• Constant licking, chewing, or scratching at one spot
• Hair loss around the affected area
• A foul smell from the skin
• Pain when the area is touched

Hot spots can appear anywhere but are most common on the head, neck, hips, and legs.

How to Help Prevent Hot Spots

While not all cases are avoidable, there are steps you can take to reduce your dog’s risk:

• Keep your dog’s coat dry: After swimming or bathing, ensure they are thoroughly dried.
• Grooming: Regular brushing helps remove loose hair and prevents matting that traps moisture.
• Flea control: Flea bites are a common trigger, so stay on top of parasite prevention.
• Check for skin irritants: Grass seeds, insect bites, or allergies can start the cycle.

Treatment at the Vet

If you suspect a hot spot, it’s important to have your dog seen by a vet promptly. These sores can become very painful and spread fast. Treatment may include:

• Clipping and cleaning the affected area to allow the skin to heal
• Medicated washes or topical treatments
• Antibiotics if infection is present
• Anti-itch or anti-inflammatory medication to break the itch–scratch cycle
• Identifying and addressing the underlying cause (such as fleas or allergies)

When to See a Vet

Hot spots are unlikely to resolve on their own and usually worsen without treatment. If you notice any signs, book an appointment as soon as possible. Early treatment means a quicker, more comfortable recovery for your dog.
