Hot Spot Care Checklist
Hot Spots in Dogs: What They Are and How to Help Your Dog Heal
A hot spot — medically called acute moist dermatitis — can go from a small patch of irritated skin to a large, oozing lesion in a matter of hours. If you notice your dog licking or chewing intensely at one area, or spot a wet, red, hairless patch, act quickly. Hot spots are painful for your dog and spread fast without treatment. This is educational content; your vet should evaluate and treat the wound.
| Factor | Details |
|---|---|
| Appearance | Red, moist, hairless, oozing, painful |
| Spread Rate | Can double in size within hours |
| Common Triggers | Allergies, insect bites, matted fur, moisture |
| High-Risk Breeds | Golden Retriever, Lab, GSD, Saint Bernard |
| Common Locations | Neck, hips, tail base, between toes |
| Key First Step | Stop the dog from licking (e-collar) |
What Causes Hot Spots
Hot spots are a cycle of self-trauma: the dog feels an itch or irritation, scratches or licks at it, breaks the skin, and the damaged skin becomes infected, which causes more itching — and the cycle escalates. Common initial triggers include flea bites, food or environmental allergies, ear infections, anal sac issues, matted fur holding moisture against the skin, and stress or boredom-related licking.
What Veterinary Treatment Looks Like
Your vet will clip the fur around the lesion (hair traps moisture and bacteria), clean the wound, and may prescribe topical or oral antibiotics to address the bacterial infection. Steroids are sometimes used short-term to relieve inflammation and itching. An e-collar is essential to break the lick-scratch-lick cycle. Identifying and addressing the underlying trigger is the key to preventing recurrence.
Preventing Hot Spots
Keep your dog’s coat clean and mat-free, especially after swimming or bathing. Address allergies and parasites proactively. Keep dogs mentally stimulated to reduce stress-licking. In dogs with known hot spot history, check skin daily during summer months or after swimming.
Frequently Asked Questions
What causes hot spots on dogs?
Hot spots (acute moist dermatitis) are caused by a dog repeatedly licking, chewing, or scratching at a spot — which breaks down the skin barrier and creates a moist, infected wound. Triggers include allergies, insect bites, matted fur, moisture trapped against skin, and stress or boredom.
Can I treat a hot spot at home?
Mild, small hot spots can be gently cleaned and kept dry while an e-collar prevents further licking, but they typically require veterinary treatment to resolve properly. Untreated hot spots spread quickly and can become severely infected. When in doubt, call your vet.
Which dog breeds get hot spots most often?
Golden Retrievers, Labrador Retrievers, German Shepherds, and Saint Bernards are among the breeds most prone to hot spots, likely due to their dense coats trapping moisture. Dogs with allergies or underlying skin conditions are also at higher risk.
