How to Prevent Hotspots on Dogs: Keep Skin Healthy

Shaving your dog to prevent hotspots can actually make them worse.
Hotspots can show up overnight and turn into raw, wet sores by morning.
They thrive where moisture, fleas, allergies, or friction meet your dog’s skin and one spot gets extra licking.
But the good news: you can stop most hotspots before they start with simple daily habits.
Dry your dog after swims and baths, keep flea prevention current, remove mats, and watch for new licking.
This post gives clear, doable steps to protect skin and what to do at the first sign of redness.

Immediate Prevention Steps to Stop Dog Hotspots Before They Start

Hotspots (acute moist dermatitis, if you want the technical term) can show up overnight. Your dog’s skin looks completely normal one evening. Next morning, you’re staring at a raw, wet, angry patch that smells terrible and won’t stop spreading. They happen when moisture, allergens, parasites, heat, or random debris irritate the skin and your dog starts licking, scratching, or chewing the same spot. That self-trauma creates a perfect little bacteria factory: warm, moist, and getting worse by the hour.

You can’t prevent hotspots with a weekly check. Prevention has to be daily, especially during warm months or anytime your dog swims, hikes, or lives outside for long stretches. The most effective approach? Interrupt the common triggers before they turn into an open sore. Keep the coat dry, manage fleas and allergens, watch for early licking, and do quick skin checks so you catch redness or moisture before it spreads.

Here are six steps you can start today:

Run your hands slowly through your dog’s entire coat once a day. Focus on behind the ears, under the collar, around the base of the tail, and in the armpits. You’re feeling for damp spots, sticky patches, or places your dog flinches when you touch.

Dry your dog completely after every bath, swim, or rain walk. Towel first, then a blow dryer on cool or low heat. Pay extra attention to thick fur, skin folds, ears, and the belly.

Rinse your dog with clean water after swimming in lakes, oceans, or pools. You’re removing chlorine, salt, algae, and pollen that cling to wet fur.

Keep year-round flea and tick prevention going. Yes, even in winter. One flea bite on an allergic dog can trigger days of scratching and a hotspot within hours.

Remove allergens when you can. Wipe paws and belly with a damp cloth after walks on high pollen days. Wash bedding weekly in unscented detergent.

Stop licking and scratching early. If your dog suddenly focuses on one spot, distract them with a toy or short training session, then check the area. If it’s red or moist, act that day.

Understanding the Causes Behind Dog Hotspots to Prevent Them

Hotspots don’t just appear randomly. They start when something irritates the skin enough to make your dog lick, scratch, or rub one area over and over. The most common triggers? Moisture trapped under a thick coat after a swim or bath. Insect bites from fleas or mosquitoes. Seasonal pollen exposure. Heat rash from lying on hot pavement or being trapped under a heavy coat. Friction from a collar or harness rubbing the same spot. Mats and debris that pull on the skin. Fungal infections like yeast overgrowth in skin folds. Food or environmental allergies. Stress-related licking.

Dogs with thick or double coats are at higher risk because their fur holds moisture and heat close to the skin. That’s the perfect environment for bacteria to multiply.

Understanding which cause is driving the problem in your dog helps you prevent the next one. A dog who gets hotspots every spring probably has pollen allergies. A dog who develops them after every lake trip needs better drying. A dog with hotspots near the collar might need a wider, softer collar or a break from wearing one indoors.

Grooming Tips to Reduce Hotspot Risk in Dogs

Regular grooming is one of the most effective ways to prevent hotspots, especially in dogs with thick or double coats. Mats trap moisture, dirt, and allergens against the skin. Loose undercoat blocks airflow. Debris like grass seeds or burrs can poke and irritate. Daily brushing during shedding season and at least every other day the rest of the year removes all of that before it becomes a problem.

When you brush, you also get a close look at the skin. You’ll notice early redness, small scabs, or damp spots that your dog might be starting to lick.

Brushing and Mat Prevention

Brush all the way down to the skin, not just the top layer. Use a slicker brush or undercoat rake for thick-coated dogs. Work in small sections and check behind the ears, under the legs, around the tail base, and along the belly. These are the spots where mats form first and hotspots follow.

For dogs with short coats, a quick once-over with a rubber curry brush or grooming mitt a few times a week is usually enough. The goal? Keep the coat loose and airy so moisture doesn’t get trapped and skin can breathe.

Safe Coat Maintenance During Summer

A lot of owners think shaving a thick-coated dog in summer will prevent hotspots, but it often makes things worse. A dog’s double coat actually insulates against heat and protects the skin from sun and allergens. When you shave it completely, you remove that protection and the coat may grow back patchy or the skin can get sunburned and irritated.

A better option is a light trim. Take an inch or two off the length, especially around the belly, armpits, and rear, but leave enough coat to protect the skin. If your dog has sensitive skin, use a gentle, hypoallergenic shampoo during baths and rinse thoroughly so no soap residue is left behind to cause itching.

Brush daily during spring and fall shedding season, every other day the rest of the year.

Remove mats gently with a mat splitter or dematting comb. If a mat is tight against the skin, have a groomer remove it safely.

After brushing, run a comb through the coat. If it catches, keep brushing.

Trim hair around the ears, paws, belly, and rear in summer to improve airflow, but never shave the entire coat.

Use hypoallergenic or oatmeal-based shampoos if your dog has sensitive or allergy-prone skin.

Moisture Control and Post‑Activity Drying to Prevent Hotspots

Moisture is one of the biggest hotspot triggers. And it’s completely preventable.

Every time your dog gets wet (bath, swim, rain, or even heavy drool around the neck), bacteria and yeast on the skin get a warm, damp environment to multiply. If the moisture stays trapped under a thick coat or in a skin fold for a few hours, your dog will start to feel itchy or uncomfortable and will lick or scratch the area. That creates the raw, oozing sore that turns into a hotspot.

The fix is simple but has to be consistent. Dry your dog thoroughly every single time they get wet.

After a lake swim, ocean dip, or pool session, rinse them first with clean water to remove chlorine, salt, algae, and any pond scum. Then towel-dry the entire coat, working the towel down to the skin. For thick-coated dogs, finish with a blow dryer on a cool or low heat setting. Hold the dryer a few inches away and keep it moving so you don’t overheat one spot. Pay extra attention to the ears (inside and out), armpits, belly, groin, and anywhere the coat is dense or the skin folds.

Here’s a safe drying routine after any water exposure:

Rinse your dog with clean water if they’ve been in a lake, ocean, or pool.

Squeeze excess water out of the coat with your hands, especially on the legs, belly, and tail.

Towel-dry the entire dog, pressing the towel into the coat rather than rubbing, which can cause mats.

Use a blow dryer on cool or low heat. Start at the head and work back, lifting the coat with your fingers or a brush as you dry so air reaches the skin.

Check ears, armpits, groin, and skin folds by touch. They should feel dry, not damp or sticky.

If your dog has a thick double coat, brush again lightly after drying to separate any clumps and restore airflow.

Parasite Prevention to Avoid Hotspots in Dogs

Fleas, ticks, and other parasites are a major cause of the intense itching that leads to hotspots. Even one flea bite can trigger an allergic reaction in sensitive dogs, causing them to scratch, chew, and lick obsessively. Flea allergy dermatitis is one of the most common reasons dogs develop hotspots, especially around the base of the tail, hips, and back legs. Ticks can cause localized irritation and infection where they attach, and the scratching that follows can quickly turn into a moist, infected sore.

Year-round flea and tick prevention is the most effective way to stop parasite-driven hotspots before they start. Use a vet-recommended product that’s appropriate for your dog’s size, age, and health. Some preventatives are topical (applied to the skin), others are oral chewables, and some combine flea, tick, and heartworm protection. Whichever you choose, stay consistent. Missing even one month during warmer weather can allow an infestation to start.

After every outdoor adventure (hikes, camping trips, or even a walk through tall grass), check your dog for ticks. Run your hands slowly over the entire body, feeling for small bumps. Check between the toes, inside the ears, around the neck, and under the legs. If you find a tick, remove it with tweezers or a tick removal tool, getting as close to the skin as possible and pulling straight out. Clean the area with mild antiseptic and watch it for a few days. If your dog starts licking or scratching the bite site repeatedly, distract them and keep the area clean and dry.

Allergy Management for Dogs Prone to Recurrent Hotspots

If your dog gets hotspots over and over, especially during certain seasons or after eating specific foods, allergies are probably involved. Environmental allergens like pollen, grass, mold, and dust make the skin itchy. Food sensitivities can cause chronic low-level inflammation that shows up as scratching, licking, and eventually hotspots. Dogs with allergies often focus their licking on the face, ears, belly, paws, groin, and base of the tail. Those are the same areas where hotspots develop most often.

Managing allergies takes some detective work, but it’s one of the most effective ways to stop recurrent hotspots.

On high pollen days, limit outdoor time during early morning and evening when pollen counts peak. After walks, wipe your dog’s paws, belly, and face with a damp cloth or hypoallergenic grooming wipe to remove pollen before they lick it off themselves. Wash bedding weekly in unscented detergent and vacuum floors regularly to reduce indoor allergens. If you suspect food allergies, talk with your veterinarian about an elimination diet or switching to a limited ingredient or hypoallergenic food.

Some dogs benefit from medications or supplements that calm the allergic response. Your vet may recommend antihistamines, prescription allergy medications, or immunotherapy depending on what’s triggering the reaction. The goal is to reduce the itching so your dog isn’t constantly licking and creating the conditions for a hotspot to form.

Rinse or wipe your dog after outdoor exposure on high pollen days.

Switch to hypoallergenic or limited ingredient dog food if food sensitivities are suspected.

Wash dog bedding and vacuum frequently to reduce indoor allergens.

Ask your vet about allergy testing, prescription medications, or immunotherapy for dogs with severe seasonal allergies.

Nutrition and Supplements to Support Skin Health and Prevent Hotspots

What your dog eats affects the health of their skin and coat, and a strong skin barrier is one of the best defenses against hotspots. Essential fatty acids, especially omega-3s from fish oil, help reduce inflammation and support the skin’s natural protective layer. Probiotics can improve gut health, and there’s growing evidence that a healthy gut supports a healthy coat and reduces allergic responses. Proper hydration is also critical. Dogs who don’t drink enough water have drier skin that’s more prone to irritation.

Make sure your dog always has access to fresh, clean water, especially during hot weather or after exercise. If your dog is prone to skin issues, consider adding an omega-3 supplement to their daily routine. Look for products that list EPA and DHA content and are specifically made for dogs. Probiotic supplements designed for canine use can also help, particularly if your dog has food sensitivities or a history of digestive issues. Some high-quality dog foods already include these ingredients, so check the label before adding extra supplements.

Stopping Licking, Scratching, and Chewing to Prevent Hotspots

The itch-lick cycle is what turns a small irritation into a full-blown hotspot. Your dog feels itchy, licks the spot, the moisture and trauma make it more irritated, so they lick more. Within hours the skin is raw and infected.

Breaking that cycle early is critical. The moment you notice your dog repeatedly licking, scratching, or chewing one area, step in. Distract them with a toy, a training game, or a frozen treat. Then check the spot they were focused on. If it’s red, warm, moist, or starting to smell, clean it gently and take steps to prevent further licking.

Physical barriers work well when distraction isn’t enough. An Elizabethan collar (the classic plastic cone) or a soft fabric cone stops your dog from reaching the area with their mouth. Bitter-tasting sprays made for pets can discourage licking, though some determined dogs ignore them. Covering the area with a light bandage or a dog shirt can also help, as long as the covering is breathable and doesn’t trap moisture. The key is to give the skin a chance to dry out and start healing without constant licking reopening the wound.

For some dogs, the licking isn’t just about an itch. It’s a response to boredom, anxiety, or stress. If your dog licks obsessively when left alone, during thunderstorms, or after changes in routine, the root cause is behavioral. Increasing exercise, providing puzzle toys, crate training with comfort items, or working with a trainer on anxiety management can reduce the compulsive licking that leads to hotspots.

Behavioral and Stress‑Related Licking

Anxiety-driven licking usually targets the same spot every time, often the paws, legs, or flanks. The dog isn’t scratching an itch. They’re self-soothing. Over time, that repetitive licking creates a hotspot even without an initial skin irritation.

If you suspect stress is the trigger, look for patterns. Does the licking start when you leave for work? During fireworks season? After a move or a new pet joins the household? Addressing the underlying anxiety through environmental enrichment, routine, training, or anti-anxiety aids (like calming supplements, pheromone diffusers, or in some cases medication from your vet) can stop the licking before it damages the skin.

Use an Elizabethan collar or soft cone if your dog won’t stop licking a spot.

Apply a vet-approved bitter spray to discourage licking, but don’t rely on it alone.

Cover minor irritations with a breathable bandage or dog shirt to block access while the skin heals.

Provide distraction with puzzle toys, frozen treats, or short training sessions when you catch early licking.

Increase daily exercise and mental enrichment for dogs who lick out of boredom or anxiety.

Breed Considerations for Dogs Prone to Hotspots

Some dogs are genetically more likely to develop hotspots. Breeds with thick double coats (Golden Retrievers, Labrador Retrievers, German Shepherds, Huskies, and Bernese Mountain Dogs) trap moisture and heat close to the skin, especially during shedding season when loose undercoat clumps together. Breeds with prominent skin folds, like Shar Peis, Bulldogs, and Pugs, have areas where moisture, dirt, and bacteria collect in the creases. Brachycephalic (flat-faced) breeds also tend to have skin fold issues around the face and can develop hotspots from drool and tear staining.

If you own a breed that’s predisposed to hotspots, prevention becomes even more important. During spring and fall shedding, brush daily and consider using a de-shedding tool to remove loose undercoat before it mats. Keep skin folds clean and dry. Wipe them daily with a soft, dry cloth or hypoallergenic wipe and check for redness or odor. Pay extra attention after your dog swims, exercises, or spends time in humid weather. A little extra grooming effort during high-risk seasons can prevent weeks of treatment and discomfort.

When Hotspots Signal a Veterinary Issue

Most small, early-stage hotspots can be managed at home if you catch them within the first few hours and your dog responds well to cleaning, drying, and preventing further licking. But some hotspots need professional veterinary care, either because they’ve progressed too far or because they keep coming back. Knowing when to call your vet can prevent a minor skin issue from turning into a serious infection or a chronic problem.

Contact your veterinarian if the hotspot is larger than a quarter (about 24 millimeters across). Lesions that size or bigger usually need prescription antibiotics because the infection has spread deeper into the skin. If the area is spreading rapidly (getting noticeably bigger within a few hours), don’t wait. Call that day.

Other red flags include pus or thick yellow or green discharge, excessive bleeding, a strong foul odor that doesn’t improve after gentle cleaning, or if your dog shows signs of pain like whimpering, snapping, or refusing to let you touch the area. Dogs with a history of recurrent hotspots, underlying allergies, or skin conditions should see a vet early so the root cause can be identified and treated.

Your vet will typically clip the fur around the hotspot to expose the full lesion and allow it to dry. They may prescribe a medicated wash, topical antibiotic ointment, oral antibiotics, anti-inflammatory medication, or pain relief depending on severity. If allergies, parasites, or fungal infections are involved, those will be treated at the same time to prevent the hotspot from coming back.

The hotspot is larger than a quarter or spreading quickly.

The area is producing pus, bleeding heavily, or smells foul even after cleaning.

Your dog is in significant pain or won’t let you examine or touch the spot.

Hotspots keep returning in the same location or your dog has a history of chronic skin problems.

Final Words

Start with daily skin checks, keep the coat dry after swims and baths, keep up flea and tick protection, and break the lick-scratch cycle early with barriers or distraction.

Tonight, do a quick hands-on check for redness, wet spots, mats, or extra licking and dry any damp areas thoroughly. Keep grooming regular and manage allergies where possible.

Call your vet if a spot grows fast, smells bad, oozes, or is bigger than a quarter. These simple steps show how to prevent hotspots on dogs and help your pet stay comfortable and healthy.
