icon Last Updated September 23, 2025

Hot spots in dogs, also known as acute moist dermatitis, are a common skin condition that many pet owners face. These red, inflamed, and often oozing patches of skin can appear suddenly and worsen rapidly, causing significant discomfort for your furry friend. While hot spots are not usually life-threatening, they can be extremely painful, irritating, and difficult to manage if not treated properly.

This comprehensive guide covers everything you need to know about hot spots in dogs, including what they are, their causes, prevention tips, treatment methods, and the best medications available. 

What Are Hot Spots in Dogs?

Hot spots are localized areas of skin inflammation and infection. They often appear as red, moist, and painful lesions that may ooze pus or have a crusty surface. Dogs with hot spots will usually lick, chew, or scratch the affected area constantly, which only makes the condition worse.

  • Painful to touch

  • Oozing pus or discharge

  • Strong odor (from bacterial infection)

  • Hair loss around the affected area

Hot spots most commonly occur on the head, chest, hips, and limbs, but they can appear anywhere on a dog’s body.

What Causes Hot Spots in Dogs?

The underlying cause of hot spots is usually skin irritation that leads to self-trauma. Once a dog starts licking, biting, or scratching excessively, bacteria can invade the skin, leading to infection.

Common Causes of Hot Spots:

  1. Allergies

    • Environmental allergens (pollen, dust, mold)

    • Food allergies (chicken, beef, dairy, grains)

    • Flea allergy dermatitis

  2. Parasites

    • Fleas, ticks, and mites are major culprits.

    • Even a single flea bite can trigger an allergic reaction and lead to a hot spot.

  3. Skin Infections

    • Bacterial or yeast overgrowth can lead to irritation and secondary infections.

  4. Poor Grooming

    • Matted fur traps moisture and bacteria against the skin.

    • Dogs with thick coats are more prone to hot spots, especially in humid climates.

  5. Moisture

    • Swimming, rain, or excessive bathing without proper drying can create an ideal environment for bacteria.

  6. Underlying Medical Issues

    • Ear infections often cause hot spots around the ears and neck.

    • Arthritis or hip dysplasia can cause dogs to chew or lick at painful areas, leading to hot spots.

  7. Stress or Boredom

    • Dogs may lick or chew themselves out of anxiety or boredom, creating hot spots.

How to Prevent Hot Spots in Dogs

Prevention is the best way to protect your dog from painful hot spots.

1. Regular Grooming

  • Brush your dog frequently to remove tangles, dirt, and loose fur.

  • Keep the coat free from mats that trap moisture.

2. Parasite Control

  • Use vet-recommended flea and tick preventatives.

FAQ
