Hot Spots in Dogs: Why They Develop and How Vets Treat Them
If your dog suddenly starts scratching, licking, or chewing a patch of skin until it becomes red, oozing, or painful, they may have a hot spot—also called acute moist dermatitis.
Hot spots are inflamed, irritated areas of skin that can develop quickly and become very uncomfortable for your dog. Understanding why they occur and how veterinarians treat them can help your dog recover faster and prevent future outbreaks.
Causes of Hot Spots
Hot spots can develop for a variety of reasons:
- Allergies: Environmental allergens, food sensitivities, or flea bites can trigger intense itching.
- Moisture: Wet fur from swimming, bathing, or rainy walks can create an ideal environment for bacteria.
- Insect bites: Fleas, ticks, and other insects can irritate the skin.
- Skin infections: Bacteria can rapidly multiply once the skin is broken or scratched.
- Underlying medical issues: Hormonal imbalances, ear infections, or joint pain can lead to excessive licking and self-trauma.
Hot spots often start small but worsen quickly if not treated, as dogs continue to lick, bite, or scratch the area.
Symptoms to Watch For
- Red, raw, or oozing patches of skin
- Hair loss around the affected area
- Foul odor from bacterial growth
- Scratching, licking, or biting at the spot
- Pain or sensitivity when touched
If you notice these signs, early intervention is key to prevent the hot spot from spreading or becoming infected.
Treatment Options
Veterinarians typically recommend a combination of treatments:
- Shaving the affected area to allow air circulation and better medication application
- Topical or oral antibiotics to fight infection
- Anti-inflammatory medications to reduce pain and itching
- Medicated shampoos or sprays to soothe the skin
- Addressing the underlying cause, such as flea control or allergy management
Hot spots can heal quickly when treated promptly—often within a week—but recurring hot spots may indicate an underlying chronic issue that needs veterinary evaluation.
