Most people assume a hot spot is a skin problem. It usually isn't; at least not at the root. The sore on your dog's skin is almost always a symptom of something else entirely, and treating only the spot is why so many of them come back.
However, hot spots are common, treatable, and something you can get to the bottom of. Understanding what's driving it is the key to helping your dog heal and keeping it from coming back.
What Is a Hot Spot, Exactly?
A hot spot is a patch of inflamed, irritated skin that develops when a dog licks, scratches, or chews at one area over and over. You may also hear your veterinarian call it acute moist dermatitis. The pattern is always the same: something makes the skin itchy or uncomfortable, your dog goes after it, and the constant attention breaks the skin down.
An itch leads to scratching, the scratching damages the skin, and the damaged skin itches even more. A raw, open patch like this can also develop into a if bacteria take hold, which is why it’s important to address it early. Breaking that loop is what brings your dog relief, and it usually starts with figuring out what triggered the itch in the first place.
What Do Hot Spots Look Like on Dogs?
Hot spots tend to be red, moist, and warm to the touch. They're often painful, and the fur around them may thin out or fall away as the area grows. They also spread fast; a small irritated patch in the morning can become a much larger sore by evening once the licking and scratching set in. Hot spots can turn up anywhere, but you'll most often find them on the head, neck, hips, and near the base of the tail.
What Causes Hot Spots on Dogs?
A hot spot is the result you can see, but the cause is almost always something underneath. Here are the triggers we come across most often.
Allergies
Allergies are one of the leading reasons dogs develop hot spots. Whether the trigger is something in the environment, an ingredient in their food, or a reaction to flea bites, the result is itchy skin. A dog dealing with that kind of persistent itch will scratch and lick for relief, and a hot spot can form quickly.
Fleas and Other Parasites
Fleas, mites, and other small pests are a frequent culprit. For some dogs, even a single flea bite is enough to set off intense itching. Year-round flea prevention is one of the simplest ways to head this off.
Ear Infections
When a dog's ears are itchy or sore, they'll often scratch at them or the surrounding area, creating a raw patch on the ear flap, behind the ear, or along the neck.
Trapped Moisture and Matted Fur
Moisture that stays against the skin is a common trigger, which is why hot spots often turn up after swimming or during humid weather. Thick or long coats that don't dry fully, along with mats that hold dampness close to the skin, are how irritation starts.
Anal Gland Problems
When a dog's anal glands are irritated or uncomfortable, they may lick and chew around the base of the tail. That repeated attention can lead to a hot spot in an area that's easy to miss under the fur.
Joint Pain, Boredom, or Stress
Sometimes the trigger isn't on the skin at all. Dogs with sore joints may lick a painful area the way we might rub an aching knee, and dogs who are bored or anxious can settle into repetitive licking that damages the skin over time.
Which Dogs Are More Prone to Hot Spots?
Some dogs are more likely to develop hot spots than others. Breeds with thick or long coats, such as Golden Retrievers, Labrador Retrievers, German Shepherds, and Newfoundlands, tend to be more prone, in part because their coats hold moisture. Dogs with floppy, drop ears are also more susceptible, as are dogs who love to swim and pets with ongoing allergies.
Hot spots can show up anywhere, but they most often appear on the head, neck, hips, and near the base of the tail.
How to Help Your Dog Find Relief
The first priority is to stop the licking and scratching that keep the sore going, since every bit of self-trauma makes it worse. Keeping the area clean and dry helps, and avoid applying human creams or ointments unless your veterinarian has recommended them, as some products can sting or make things worse.
Because hot spots are usually a symptom of an underlying issue, lasting relief comes from identifying and treating whatever started the itch. Your veterinary team can care for the sore itself and help you get ahead of the cause, so your dog isn't stuck in the same cycle a few weeks down the road.
When to See Your Vet About a Hot Spot
Have your dog seen if a hot spot is spreading quickly, oozing, giving off an odor, or simply not improving. Also pay attention to recurring hot spots, since they often point to a root cause that hasn't been fully addressed.
At , we offer same-day and weekend appointments, so your dog can be seen when they need care rather than days later.
Preventing Hot Spots
A few consistent habits go a long way toward keeping hot spots from starting. Stay on top of flea prevention, groom your dog regularly to avoid mats, and dry their coat thoroughly after baths and swims. Keeping ongoing issues like allergies and ear health well managed also removes the itch before it has a chance to become a sore.
Frequently Asked Questions
Can hot spots heal on their own?
Some mild spots may settle down once the itching stops, but many need care to heal fully, especially if a dog keeps licking the area. Because hot spots can spread fast and usually stem from an underlying issue, have your dog checked rather than wait and see.
Are hot spots contagious to other pets or people?
Hot spots themselves aren't contagious. That said, some of the root causes, such as certain parasites, can affect other pets, so it's worth pinning down the cause.
How quickly do hot spots develop?
Very quickly. A hot spot can go from a small irritated patch to a large, painful sore within hours once a dog starts licking and scratching in earnest.
Can I treat my dog's hot spot at home?
You can help by keeping the area clean and dry and stopping your dog from licking it, but home care alone often isn't enough. Reaching out to your veterinary team is the best way to treat the sore and address what caused it.
