Hot spots on dogs are one of the most common skin issues dog parents notice “out of nowhere.” Also called acute moist dermatitis, they can show up fast and look alarming. They can get worse quickly if your dog keeps licking or scratching the area. The good news: once you know what to look for and what typically causes them, you can act early. This helps your dog get comfortable again.
What Hot Spots on Dogs Look Like
Hot spots are usually:
- Red, inflamed patches of skin that can look raw
- Moist or oozing areas (sometimes with a shiny, wet appearance)
- Hair loss around the spot where the fur looks matted or thinned
- A strong urge to lick, chew, or scratch the area
- Tender to the touch—some dogs pull away when you touch it
They often appear on the neck, cheeks, hips, thighs, or base of the tail. They can show up anywhere. Irritated, damp skin often develops a noticeable odor and may become infected. According to the American Kennel Club, hot spots are especially common during summer months and can spread rapidly once the skin b
Common Causes of Hot Spots
Something irritates the skin first. Licking and scratching follow, and this breaks down the skin barrier. Once the skin is damaged, bacteria multiply quickly—especially in warm, humid conditions.
Here are the most common causes:
- Allergies (environmental, food, contact irritation)
- Fleas and other parasites
- Moisture trapped in the coat (swimming, baths, rain, humidity)
- Matting and poor airflow to the skin
- Skin wounds or irritation
- Ear infections (dogs with itchy ears may scratch and rub, creating irritation on the neck or cheek area)
What to Do If You Suspect a Hot Spot
- Prevent licking and chewing (an e-collar or cone is often needed)
- Keep the area clean and dry
- Avoid human creams or random home remedies—some trap moisture or irritate the skin further
Preventing Hot Spots on Dogs
A few consistent habits often prevent hot spots:
- Keep up with flea prevention
- Dry your dog thoroughly after baths or swimming
- Brush regularly to prevent mats and improve airflow
- Address allergies early (itching is a warning sign)
- Check ears and skin weekly—catching irritation early makes a big difference
