Dog scratching itself

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.

When to See a Vet

See your vet immediately if:

  • The hot spot is large or spreading rapidly
  • Your dog is in obvious pain
  • There are multiple hot spots
  • Home treatment isn’t working in 48 hours

Prevention Tips

  • Regular grooming to prevent matting
  • Thorough drying after swimming or bathing
  • Flea prevention year-round
  • Address allergies with your vet
  • Reduce stress with exercise and enrichment
  • Quick treatment of any skin issues
