Hot Spots (Acute Moist Dermatitis)

descriptionOverview

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.

• warningIntense itching and pain at the site
• warningHair loss around the affected area
• warningFoul smell from bacterial infection
• warningConstant licking or chewing at one spot

restaurantHow 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.

Keep dogs dry after swimming — trapped moisture under the coat is a major trigger. Regular grooming prevents matted fur that traps heat and moisture.
