Hot Spots on Dogs: Causes, Treatment, and Prevention
Lillian Ruff Pet Spa
Hot spots, also called acute moist dermatitis, are painful, red, oozing skin lesions that can appear suddenly and spread rapidly. They’re one of the most common skin conditions in dogs.
What Are Hot Spots?
Hot spots are areas of inflamed, infected skin caused by:
- Self-trauma from scratching, licking, or chewing
- Bacterial infection on damaged skin
- Moisture trapped against the skin
Common Causes
Allergies
- Food allergies
- Environmental allergies (pollen, dust, mold)
- Flea allergies (most common cause)
Moisture
- Poor drying after swimming or bathing
- Humid weather
- Dense undercoat trapping moisture
Skin Irritation
- Matted fur
- Insect bites
- Scratches or wounds
- Ear infections (causing head scratching)
Behavioral
- Boredom
- Anxiety
- Stress
Signs of Hot Spots
- Red, moist, irritated skin
- Hair loss in the area
- Constant licking, scratching, or chewing
- Oozing or pus
- Foul odor
- Pain when touched
- Rapid spreading
Treatment Steps
1. Clip the Fur
Carefully trim hair around the hot spot to expose the area to air.
2. Clean the Area
Gently clean with an antiseptic solution or diluted chlorhexidine.
3. Apply Medication
Use vet-prescribed topical treatments (antibiotics, hydrocortisone).
4. Prevent Licking
Use an e-collar (cone) to prevent further trauma.
5. Address the Cause
Identify and treat the underlying issue.
