Hot Spots on Dogs: Causes, Diet, and Prevention
7-minute read · Loyal Saints Health Library
Quick answer
Hot spots (acute moist dermatitis) are red, inflamed, often oozing skin lesions that develop rapidly, usually from scratching or licking triggered by allergies, moisture, or irritation. Diet supports prevention by reducing allergic inflammation with clean, single-protein nutrition and omega-3s; active hot spots need veterinary care.
Hot spots are localized areas of inflamed, infected skin that appear suddenly and can spread quickly. They typically start when a dog licks, scratches, or chews an itchy area — often triggered by allergies (food or environmental), fleas, moisture trapped in the coat, or irritation — creating a moist, raw, bacteria-prone lesion.
Because allergies and skin inflammation are common underlying triggers, diet plays a real preventive role. A clean, single-protein diet that removes common food allergens reduces the allergic itch-scratch cycle, and omega-3 fatty acids support a stronger skin barrier. Active hot spots, however, need prompt veterinary care — clipping, cleaning, and often medication.
Key points
Itch-scratch cycle
Hot spots start from licking/scratching an itchy, often allergy-driven area.
Diet reduces triggers
Clean, single-protein nutrition lowers the allergic inflammation behind the itch.
Omega-3s support skin
Strengthen the skin barrier, helping resilience against flare-ups.
Active spots need a vet

Preventing hot spots means addressing the underlying itch. For allergy-prone dogs, Loyal Saints' clean, single-protein, allergen-free formulas plus omega-3 support help reduce the inflammation that drives scratching. Keep the coat dry and groomed, control fleas, and see your vet for any active hot spot.

Frequently Asked Questions
What causes hot spots on dogs?
Hot spots usually start from licking or scratching an itchy area, triggered by allergies (food or environmental), fleas, trapped moisture, or irritation. The moisture and bacteria create a rapidly spreading inflamed lesion. Allergies are a common underlying driver.
Can diet help prevent hot spots?
Yes — since allergies often drive the itching that causes hot spots, a clean, single-protein diet that removes common food allergens, plus omega-3s for the skin barrier, can reduce the inflammation behind flare-ups. Diet is preventive; active hot spots need veterinary treatment.
How do I treat a hot spot at home?
Active hot spots are best treated by a veterinarian, who will clip and clean the area and may prescribe medication. At home you can prevent worsening by keeping your dog from licking it and the area dry, but see your vet promptly, as hot spots spread quickly.
Why does my dog keep getting hot spots?
Recurrent hot spots usually mean an unaddressed underlying cause — commonly allergies, fleas, or moisture issues. Identifying and managing the trigger (often dietary or environmental allergies, with veterinary guidance) is key to prevention.
