Red, wet, and angry-looking - that's what a hot spot looks like on your dog's skin. You swear it wasn't there yesterday. The fact is, it probably wasn't, at least not visibly so.
What are hot spots in dogs? The clinical name for a hot spot is acute moist dermatitis. It’s a localized area of inflammation that causes intense itching, and it can indeed develop within hours. It will also get worse quickly if it's not treated.
It's that sudden development that makes hot spots in dogs particularly stressful and gives you that sinking feeling in the pit of your stomach. What appears small in the morning can look like a significant wound by evening. That's why you need to understand hot spots and know what to do about them. At Vidge Pets, we believe that knowledgeable pet parents are the best prevention against your dog's discomfort.
This guide covers everything you need to know about hot spots: causes, appearance, treatment, natural care options, and prevention.
What are Hot Spots in Dogs?
Hot spots are patches of skin that are inflamed and infected with bacteria. What do hot spots in dogs look like? They appear pink or red, have a wet look, and are painful. Your dog actually creates them by disrupting the skin's surface when scratching or licking, which allows normal bacteria to proliferate and cause an infection. Crusting may appear around the edges, and the fur is often missing due to your dog’s licking and scratching. There is usually a distinct boundary between healthy and affected skin.
Common locations of hot spots include:
-
Neck
-
Ears
-
Hips
-
Base of the tail
-
Between the toes
Basically, a hot spot can appear anywhere your dog can lick or scratch repeatedly. The size of a hot spot can vary. Some are as small as coins, while others can be palm-sized within just a few hours. Any breed of dog can get one, although dogs with thick, dense coats tend to be more susceptible.
What Causes Hot Spots in Dogs?
All dog parents should learn what causes hot spots in dogs, because many get them more than once. They're created the same way every time: something makes your dog itchy, and then they start scratching, licking, and biting at a particular area repeatedly. The skin's protective barrier breaks down, and bacteria set in. Inflammation increases, and in response, the dog scratches more than ever, creating a vicious cycle.
The Causes of Hot Spots in Dogs Include:
-
Allergies: food-related, environmental (pollen, grass, dust), or contact allergies
-
Flea bites or other parasitic irritations: one single flea can start the itch-scratch cycle and lead to a hot spot in some dogs.
-
Ear infections: If a dog has an ear infection, they're more prone to scratching around the neck and the base of the ear, which can lead to a hot spot.
-
Matted or dirty fur: Moisture gets trapped against the skin, and that encourages bacterial growth.
-
Boredom, stress, or anxiety: Yes, behavioral issues can cause hot spots, too, due to compulsive licking.
-
Minor skin trauma: abrasions, insect bites or stings, small cuts, anything that bothers your dog enough that it won't leave the area alone.
What causes hot spots in dogs' skin to worsen so rapidly is the cycle: broken skin invites bacteria, increasing inflammation, which intensifies itching, and itching leads to scratching. The earlier in that cycle you can stop it, the better.
Why Do Dogs Get Hot Spots in Summer?
Hot spots can occur any time of year, so you have to watch for them year-round. However, the warmer months are when they are most common, and there are good reasons for that. The heat and humidity create ideal conditions, especially if the fur gets damp, for bacteria to multiply faster than the skin's defenses can keep up.
Also, summer activities make it riskier. Dogs go swimming, spend more time outdoors, and are exposed to grass, pollen, and insects, which can cause seasonal allergies. Dogs with thick double coats, like Golden Retrievers, Labrador Retrievers, and Huskies, are especially prone to moisture getting trapped beneath the outer coat layer. Obviously, there are many answers to the question, “Why do dogs get hot spots in the summer?” Again, early treatment is especially important. The sooner you can interrupt the cycle, the less damage there will be to the skin and the more comfortable your dog will be.
How to Treat Hot Spots in Dogs![How to treat hot spots in dogs]()
Treatment for hot spots in dogs is most effective when it is started at the first sign of a problem. If you don't treat a hot spot right away, it just gets worse. The infection gets deeper, and the area becomes more painful. That doesn't mean you need an immediate vet visit. Mild cases can often be treated at home following these steps:
(1)Trim the fur around the area.
Carefully clip the hair all the way around the hot spot to allow airflow and prevent additional moisture from accumulating.
(2) Clean the area, gently.
Remove surface bacteria and debris with an antiseptic solution.
(3) Apply a soothing topical.
A reduction in redness, calming of irritation, and a less favorable environment for bacteria can be achieved with a gentle anti-inflammatory product, which will discourage further licking.
(4) Use an E-collar.
Even if it bothers you to see your dog wearing this, it is one of the most important steps involved in treating hot spots in dogs. You have to stop your dog from licking the area, or it won't heal.
(5) Monitor for 24 to 48 hours.
If you've started hot spots in dogs treatment while the hot spot is new, you should see definite improvement within this time frame.
If a hot spot is spreading too rapidly, appears deeply infected, or isn't responding to home care, then you need to involve a vet. They can provide stronger anti-inflammatory or antibiotic support and ensure there's no deeper underlying cause.
Now you know how to treat hot spots in dogs.
Natural Ingredients That Help Calm Hot Spots at Home
Many pet parents are increasingly turning to natural approaches to treat conditions their dogs develop, especially when they're mild or caught early. A hot spot is one of those conditions that may do well with home treatment. Several natural ingredients are well established for soothing skin and supporting the skin barrier. These ingredients show how to treat hot spots in dogs at home.
What natural ingredients calm hot spots in dogs?
-
Aloe vera is useful for inflamed skin and surface irritation as it provides a cooling effect.
-
Colloidal oatmeal reduces itching and surface-level inflammation.
-
Chamomile extract is often found in topical skincare formulations because it is a gentle anti-inflammatory.
-
Coconut oil is valued for its mild antimicrobial activity and moisturizing properties.
-
Omega fatty acids, which can be obtained from fish oil or plant-based options, support the skin barrier from the inside out.
Effective hot spot treatment in dogs depends on the stage and cause, but treating from the inside out and from the outside in are both important. If your dog has a healthy, intact skin barrier, it's less susceptible to the bacteria that cause hot spots. In addition, supporting daily skin health with a skin and coat supplement for dogs helps maintain the skin barrier and prevent hot spots from forming.
How to Prevent Hot Spots in Dogs
There's no way to eliminate the risk of hot spots completely, but consistent daily skin care will drastically reduce how often your dog gets a hot spot and how severe it becomes. Dogs that have already had a hot spot are especially prone to having another one. For these dogs, prevention is a priority.
The following strategies will show how to prevent hot spots in dogs and include:
-
Regular grooming - Brushing removes mats, improving airflow. It allows early detection of changes in the skin.
-
Drying fur thoroughly - It's important to keep the undercoat areas free of moisture after swimming or bathing.
-
Allergy management - Minimizing exposure to triggers, such as environmental allergens or certain foods, can reduce the urge to scratch.
-
Flea and parasite prevention - One of the most common irritating causes of itchiness in dogs is fleas, therefore making it essential to maintain consistent parasite control.
-
Skin-supportive nutrition - You can help your dog build a stronger, more resilient skin barrier by ensuring its diet is rich in omega-3 and omega-6 fatty acids and by providing targeted supplements.
-
Reducing stress and boredom - Stress can lead to anxiety, which can lead to compulsive licking, all of which may be reduced by enrichment, exercise, and mental stimulation.
There's no single approach that can address how to prevent hot spots in dogs, but combining several of these strategies can significantly reduce the overall risk.
When to See a Vet for Hot Spots in Dogs
If you catch hot spots in dogs in their early stages, home care will often do the trick. At any rate, there's never a reason to panic at the first sight of one. There are certain signs, though, that indicate professional treatment is needed. Take your dog to the vet if you notice:
-
The hot spot is bigger than your palm and spreads within hours.
-
The wound seems deep rather than superficial.
-
There appears to be a significant infection, as evidenced by pus, a strong odor, swelling, or warmth beyond the immediate area.
-
Your dog is so uncomfortable that it's lethargic or not eating.
-
There's been no improvement after 48 to 72 hours of home care and monitoring.
-
Recurring hot spots in the same area can indicate an underlying allergy or condition.
If any of these occur, your vet can prescribe antibiotics or anti-inflammatory medications, or perform any necessary testing to identify an underlying trigger, such as a food allergy or atopic dermatitis. Treating hot spots in dogs often includes finding the underlying cause to provide faster, more targeted relief.
As scary as they look, hot spots tend to go away quickly and fully with the right treatment. And if you apply preventive strategies, you may have fewer to deal with in the future.
FAQs
What are hot spots in dogs?
Hot spots in dogs are areas of skin that look infected, raw, and painful, and can appear suddenly and worsen within hours. They can also feel warm to the touch, look wet, and make your dog very uncomfortable. The reason they develop so quickly is the cycle that causes them: something makes your dog itchy, and it licks or scratches, which damages the skin, which makes the itch worse, which leads to more licking. Hotspots are common, especially in dense-coated and allergy-prone breeds.
What causes hot spots in dogs?
Some dogs are simply more predisposed. Breeds with heavy, dense coats are more likely to trap moisture in their fur. Dogs with a history of allergies are more likely to become itchy. Anxious dogs may lick compulsively. Any of these predisposing factors can cause a hot spot if a flea bites the dog, the dog develops a damp coat, or the dog experiences a stressful event.
How do I treat hot spots in dogs at home?
If you catch the hot spot in its early stages, you should immediately do three things: stop the licking with an E-collar, clean the area by first trimming the surrounding fur, then gently wiping it with a mild antiseptic, and apply a soothing topical. That’s how to treat hot spots in dogs at home. It's important to monitor closely because if there's no improvement within 48 to 72 hours, your vet should take a look.
What natural ingredients help calm hot spots?
There are several, including colloidal oatmeal, which forms a physical protective layer on the skin's surface. This helps interrupt the itch-scratch cycle. Aloe Vera has a cooling effect that helps calm inflamed tissue. Chamomile has anti-inflammatory activity. And giving omega fatty acids internally helps rebuild the skin barrier’s lipid layer, making it harder for bacteria to enter. What natural ingredients calm hot spots in dogs is often a combination of topical treatment and internal barrier support.
Why does my dog get hot spots every summer?
The heat and humidity of summer accelerate bacterial growth on the skin. Also, outdoor allergens like grass and pollen increase, causing more scratching, and swimming leaves moisture trapped in the coat. Why do dogs get hot spots in the summer can also be the result of atopic dermatitis flare-ups. If you have a dog with this recurring pattern, it's useful to manage their allergies year-round and maintain a consistent skin barrier.
How can I prevent hot spots in my dog?
Prevention is especially important for dogs that have already had hot spots. Instead of a single practice, small daily habits will make prevention most effective. Regular brushing, drying your dog after exposure to water, flea prevention, and monitoring are key. How to prevent hot spots in dogs from recurring involves maintaining an ongoing routine rather than a one-time fix. Consistency is important, as is using multiple habits rather than just one thing.
When should I take my dog to the vet for a hot spot?
A hot spot on your dog that’s mild can be watched for 24 hours as you try home care. If the hot spot is spreading rapidly, shows signs of deep infection, or is causing your dog tremendous pain, your dog should see a vet. Also, hot spots near the eye or ear should be seen sooner rather than later, as these areas contain sensitive structures. And if your dog is lethargic or isn't eating, that shouldn't wait either.
