If you have found a raw, oozing patch on your dog and it was not there yesterday, you are probably looking at a hot spot. They are common, especially in warm, humid weather and in dogs with thick coats. This guide covers what they look like, why they happen, what you can safely do at home while you arrange care, and how to stop them returning.
What a hot spot looks like
- A red, moist or weeping patch, often with matted fur stuck to it.
- Hair loss around the area, a smell, and sometimes crusting or pus.
- Constant licking, chewing or scratching at one spot.
- Pain: many dogs flinch, growl or pull away when the area is touched.
- Common places: the head and cheeks, the neck, the hips and the base of the tail, and the legs.
Why hot spots start
Anything that makes a dog itch or lick can start the cycle: the itch leads to scratching, scratching damages the skin, moisture and bacteria move in, and the area gets itchier. Common triggers include:
| Trigger | Why it leads to a hot spot | Where to read more |
|---|---|---|
| Fleas and other parasites | Bites cause intense itching, often near the hips and tail base. | Flea and tick prevention |
| Allergies | Environmental or food allergies make skin itchy and inflamed. | Why is my dog itching? |
| Ear or anal gland problems | Discomfort nearby leads to scratching or licking the area. | Dog ear infection, scooting |
| Trapped moisture | A damp, thick coat after swimming or a bath that is not dried well. | How often to bathe your dog |
| Matted fur | Mats hold moisture and irritate skin underneath. | Removing mats safely |
| Boredom or stress licking | Repetitive licking of one spot can damage skin. | Indoor activities |
Safe first aid while you arrange a vet visit
Hot spots are painful and can deepen quickly, so most owners should call their vet the same day. Until then, these steps are generally considered low risk:
- Stop the licking. A cone (e-collar) or a soft recovery collar is the simplest way to prevent more damage.
- Keep the area clean and dry. Gently rinse with lukewarm water and pat dry. Ask your vet which antiseptic is safe for your dog before using one.
- Do not bandage it. Covering a hot spot can trap heat and moisture.
- Be careful with clipping. Clipping away matted fur helps the skin dry out, but a painful dog may bite. If your dog resists, let the vet or groomer do it.
- Skip human creams. Do not use human steroid or antibiotic products unless your vet says so, because dogs lick them off.
What treatment usually involves
A vet will usually clip and clean the area, then decide on medicated treatment to calm the inflammation and treat infection if present. Some dogs need sedation because the area is so sore. The vet will also look for the underlying cause, such as parasites, allergies or an ear problem. Treating only the patch without finding the cause is why many hot spots come back. Never give your dog human pain relief or leftover medication.
When to go to the vet right away
- The patch is growing quickly or is bigger than a coin.
- There is pus, a strong smell, or bleeding.
- Your dog is lethargic, not eating, or seems unusually painful.
- There are several patches, or the same spot keeps returning.
- You are not sure it is a hot spot. Ringworm, mange and some skin tumors can look similar, which is one reason a vet check matters.
What recovery usually looks like
Once a vet has cleaned the area and started treatment, many hot spots improve quickly. The American Kennel Club notes that a hot spot can resolve in as little as three to seven days after treatment begins, though deeper infections or an untreated cause can take longer. Dogs with thick coats, such as Saint Bernards, German Shepherds, Labrador Retrievers and Rottweilers, are listed by the AKC as more prone to hot spots, and warm, humid weather raises the risk for any dog. If the patch is not clearly improving within a few days of treatment, go back to your vet rather than waiting.
Hot spots are painful and can spread, but PetMD notes it would be extremely rare for one to be fatal in an otherwise healthy dog. The bigger risk is delay: the longer a dog keeps licking, the deeper the skin damage and infection can become.
Preventing hot spots
- Keep flea and tick prevention up to date, as your vet recommends.
- Brush regularly and remove mats early, especially on thick or long coats.
- Dry your dog thoroughly after swimming and baths, including under the collar and in skin folds.
- Ask your vet about allergy management if itching is seasonal or ongoing.
- Give regular exercise and mental work so licking does not become a habit.
Frequently asked questions
Are hot spots contagious?
Hot spots themselves are not contagious. The underlying cause, such as fleas, can be shared between pets, so ask your vet about treating every animal in the home if parasites are involved.
Can a hot spot heal on its own?
A very small, early patch sometimes settles, but most keep growing while the dog keeps licking. Because they are painful and can become infected, a vet check is the safer choice.
Which dogs get hot spots most?
Any dog can, but thick-coated, water-loving and allergic dogs are often affected. Heat and humidity raise the risk.
Is a hot spot an emergency?
Not usually a life-threatening one, but it can worsen within hours. Same-day veterinary advice is a sensible rule.
