Overview
Hot spots are localized areas of inflamed, infected skin that appear suddenly and spread rapidly. They start when a dog scratches, licks, or chews an itchy area — breaking the skin and allowing bacteria to invade. Within hours, a small irritation becomes a large, oozing, painful lesion. Common triggers include flea bites, allergies, swimming, and matted fur trapping moisture.
Symptoms to Watch For
- Red, moist, oozing skin lesion that appears rapidly
- Intense itching and pain at the site
- Hair loss around the affected area
- Foul smell from bacterial infection
- Constant licking or chewing at one spot
How Nutrition Helps
Omega-3 fatty acids reduce skin inflammation and itching, making hot spots less likely to develop. A strong skin barrier (supported by omega-6 linoleic acid and zinc) resists bacterial invasion. Addressing underlying food allergies through elimination diets prevents the itching that triggers hot spots in the first place.
How Activity Helps
Keep dogs dry after swimming — trapped moisture under the coat is a major trigger. Regular grooming prevents matted fur that traps heat and moisture.
Prevention Tips
- Dry your dog thoroughly after swimming or bathing
- Regular grooming to prevent matting
- Address flea prevention year-round
- Supplement with fish oil for skin health
- Address underlying allergies with your vet
Breeds at Higher Risk
Golden Retrievers, Labradors, German Shepherds, Rottweilers, and Saint Bernards — breeds with thick, dense coats.
