Labrador Hot Spot Treatment: Best Sprays & Home Care (2026)

By Emiel Maddens  ·  Reviewed in consultation with licensed veterinary professionals  ·  Updated June 2026  ·  25 min read

Few things are as alarming to a Labrador owner as discovering a hot spot. Your dog was fine this morning, and now there is a raw, oozing, angry-looking patch of skin that seems to be growing by the hour. Your Lab is frantically licking, biting, or scratching the area, making it worse with every pass. The fur around it is matted with moisture and discharge, and the smell is unmistakable.

Hot spots, known in veterinary medicine as acute moist dermatitis or pyotraumatic dermatitis, are one of the most common skin problems in Labradors. The breed's thick double coat, love of water, and predisposition to allergies create a perfect storm for these painful bacterial skin lesions. The good news is that when caught early, most hot spots can be treated effectively at home with the right approach and the right products.

This guide is a comprehensive, breed-specific resource for Labrador owners dealing with hot spots. We will cover why Labs get hot spots more than almost any other breed, how to treat them step-by-step at home, which sprays and products work best, when home treatment is not enough, and how to reduce the frequency of future hot spots. For a broader overview of hot spots across all breeds, see our complete guide to hot spots in dogs.

Why Labradors Get Hot Spots More Than Other Breeds

Labradors consistently rank among the top breeds affected by hot spots in veterinary dermatology studies, alongside Golden Retrievers, German Shepherds, and Saint Bernards. Several breed-specific factors explain this predisposition.

The Labrador double coat: a moisture trap

The Labrador Retriever was originally bred for retrieving waterfowl in the cold waters of Newfoundland, and its coat reflects that purpose. Labs have a dense, water-resistant double coat consisting of a short, thick, straight outer coat and a soft, insulating undercoat. This coat is remarkably effective at keeping water out during a quick swim, but when a Lab gets thoroughly wet (a long swim, a bath, playing in rain), the dense undercoat absorbs and retains moisture against the skin. Unlike single-coated breeds that air-dry quickly, a Labrador's undercoat can remain damp for hours or even days if not dried properly.

This trapped moisture softens the skin barrier, disrupts the skin's natural pH, and creates the warm, humid microenvironment that bacteria need to proliferate. The result is a perfect breeding ground for Staphylococcus pseudintermedius, the bacterium responsible for the vast majority of canine hot spots. The heaviest parts of the coat, typically around the neck, behind the ears, on the rump, and along the flanks, are the most common hot spot locations in Labs because these areas retain the most moisture.

Water-loving behavior compounds the problem

Labs are not just equipped for water; they actively seek it out. Ponds, lakes, sprinklers, puddles, and garden hoses are all irresistible to most Labradors. This constant exposure to water means the coat rarely gets a chance to dry completely during active months, and each swimming session resets the moisture clock. Labs that swim in lakes, ponds, or the ocean face additional risk from waterborne bacteria and irritants that can initiate the inflammatory process leading to a hot spot. For more on swimming-related ear and skin issues in Labs, see our article on dog ear infections after swimming.

High rates of environmental allergies

Labradors have a well-documented genetic predisposition to atopic dermatitis (environmental allergies). Studies estimate that 10% to 15% of all Labradors have some degree of atopic dermatitis, making it one of the most affected breeds. Allergies cause generalized skin itching and inflammation, which leads to scratching, licking, and biting, and this self-trauma is the most common trigger for hot spots. An allergic Lab that scratches an itchy ear, licks an irritated flank, or chews at a reaction site creates the initial skin break that bacteria exploit to form a hot spot. For more on Lab-specific allergy issues, see our comprehensive guide on why Labradors are so itchy.

Flea sensitivity and outdoor exposure

Labs are typically high-energy outdoor dogs that spend significant time in grass, woods, and fields, areas where fleas, ticks, and biting insects thrive. A single flea bite on a flea-allergic Lab can trigger intense localized itching that spirals into a hot spot within hours. The thick undercoat makes it harder to spot fleas early, and the dog's constant scratching at the bite site quickly damages the skin surface. Even a Lab without flea allergy can develop hot spots from the simple irritation of insect bites, burrs, or contact with irritating plants during outdoor adventures.

Ear infections as hot spot triggers

Labradors are also prone to ear infections because of their floppy ears, which trap moisture and create a warm, dark environment inside the ear canal. An itchy ear infection causes the dog to scratch at the ear and the surrounding skin, and hot spots on the cheek, behind the ear, or on the side of the neck frequently start as a secondary consequence of the dog scratching at an infected ear. This is so common in Labs that whenever a hot spot appears near the ear, the ear itself should be checked for concurrent infection. For more on this common Labrador issue, see our detailed guide on Labrador ear infections.

How Hot Spots Develop: Understanding the Cycle

Understanding how a hot spot forms helps you treat it more effectively and, more importantly, prevent future ones. Hot spots follow a predictable cycle.

Stage 1: The initial trigger

Something causes localized itching or irritation. The most common triggers in Labradors are flea bites, allergic reactions (environmental or food), ear infections that cause scratching, moisture trapped under the coat after swimming, matted fur pulling on the skin, minor wounds, insect bites, or contact irritants. The trigger itself may be minor, but it prompts the dog to scratch, lick, or bite at the area.

Stage 2: Self-trauma and skin barrier breakdown

The dog's scratching, licking, or biting damages the skin surface, creating microscopic (or not so microscopic) breaks in the skin barrier. Licking introduces oral bacteria to the damaged skin. The moisture from saliva further softens the already-compromised skin. In a Lab's dense coat, the damaged area stays moist and hidden, allowing the problem to escalate before the owner notices.

Stage 3: Bacterial infection and rapid expansion

Staphylococcus bacteria, which normally live on the skin surface in small numbers without causing problems, seize the opportunity to invade the damaged, moist skin. They multiply rapidly in the warm, wet environment under the coat, releasing toxins that cause inflammation, pain, and intense itching. This creates a vicious feedback loop: the infection makes the area more itchy, the dog scratches and licks more aggressively, the skin damage worsens, and the infection spreads outward from the original site. This is why hot spots can appear to "explode" in size, sometimes doubling or tripling in area within 12 to 24 hours.

Stage 4: Established lesion

A fully developed hot spot appears as a well-demarcated, moist, red, raw, often circular or oval area of skin. The surface is typically oozing serum or pus. The surrounding fur is matted with discharge. The area is painful to touch and intensely itchy. There is often a noticeable "hot" feeling (hence the name) because the inflammation raises the local skin temperature. The lesion has a sharp border where healthy skin meets infected skin.

How to Treat a Labrador Hot Spot at Home: Step-by-Step

When you discover a hot spot on your Lab, speed matters. The faster you intervene, the smaller the lesion stays and the faster it heals. Here is the complete home treatment protocol.

Step 1: Clip the fur around the hot spot

This is the most important first step, and the one most owners skip because they do not want to create an unsightly bald patch. However, clipping the fur is absolutely essential for effective treatment. You need to clip a margin of at least half an inch to one inch beyond the visible edges of the lesion. This does several critical things: it exposes the full extent of the lesion (hot spots are almost always larger under the matted fur than they appear from the surface), it removes the matted fur that is trapping moisture and bacteria against the skin, it allows air to reach the skin surface, and it allows topical medications to make direct contact with the affected skin.

Use electric clippers with a #10 or #40 blade if available. Scissors can work in a pinch but risk nicking the inflamed skin. Clip carefully, as the skin around a hot spot is sensitive and your Lab will likely flinch. If the lesion is very painful and your dog will not tolerate clipping, this is a sign that veterinary sedation may be needed for proper treatment.

Step 2: Gently clean the lesion

Once the fur is clipped and the full lesion is exposed, clean the area gently. Use a mild antiseptic solution (dilute chlorhexidine solution at 0.05% to 0.5% is ideal) or simply lukewarm water on a soft gauze pad. Gently wipe away the dried discharge, pus, and debris from the surface of the hot spot. Do not scrub aggressively, as the skin is raw and painful. Work from the center outward to avoid pushing debris into the wound. Pat the area dry with a clean gauze pad after cleaning.

Step 3: Apply antiseptic treatment spray

This is where the right product makes all the difference. You need a spray that kills the Staphylococcus bacteria driving the infection, provides residual antimicrobial activity between applications, and is gentle enough for application on raw, inflamed skin. A chlorhexidine-based spray is the gold standard for hot spot treatment. Chlorhexidine gluconate at 2% concentration kills Staphylococcus on contact and has a unique residual binding property: it binds to skin proteins and continues providing antimicrobial activity for hours after application, even as the surface dries. For a deeper understanding of how this active ingredient works, see our comprehensive guide to chlorhexidine for dogs.

Spray the treatment directly onto the cleaned hot spot, covering the entire lesion and extending slightly beyond the borders onto the surrounding clipped skin. Allow the spray to air-dry. Do not wipe it off or bandage over it. Hot spots heal best when exposed to air.

Step 4: Prevent your Lab from licking or scratching the area

This is the biggest challenge in hot spot treatment. Your Lab's instinct is to lick and scratch the area, which reintroduces bacteria, adds moisture, and re-traumatizes the healing skin. An Elizabethan collar (cone) is the most reliable option. It is not fun for anyone, but it is the single most effective intervention for preventing self-trauma during healing. If your dog absolutely cannot tolerate a cone, inflatable recovery collars or medical body suits can provide partial protection, but they are generally less effective than a proper E-collar for determined lickers.

Step 5: Repeat treatment 2 to 3 times daily

For the first 3 to 5 days, clean the hot spot gently and reapply antiseptic spray 2 to 3 times daily. You should see improvement within 24 to 48 hours: the oozing should decrease, redness should begin to fade at the edges, and the lesion should stop expanding. Continue treatment for 7 to 10 days or until the area is dry, no longer red, and showing signs of new skin growth. Do not stop treatment when the hot spot "looks better" but is still slightly pink or moist. Incomplete treatment leads to rapid recurrence.

Best Treatment Sprays for Labrador Hot Spots

Not all sprays are created equal. Here are our evidence-based recommendations for the best hot spot treatment sprays for Labradors, along with a comparison of the major options. For a broader comparison across all brands, see our guide to the best hot spot sprays for dogs.

Best for hot spot treatment: Vetified Chlorhexidine Spray

Active ingredients: 2% Chlorhexidine Gluconate + 1% Ketoconazole

Size & price: 8 fl oz, $19.97

Registration: FDA-registered (NDC 86247-002-08), manufactured by Vetio Animal Health

The Vetified Chlorhexidine Spray is our top recommendation for treating Labrador hot spots. Hot spots are fundamentally bacterial infections, and chlorhexidine gluconate at 2% is the most effective topical antiseptic for Staphylococcus, the bacterium driving the infection. The inclusion of 1% ketoconazole adds antifungal coverage, which matters because Labs with underlying allergies frequently have concurrent Malassezia yeast involvement in their skin problems.

What makes this spray particularly well-suited for hot spots is the combination of immediate bactericidal action (chlorhexidine kills on contact), residual activity (chlorhexidine binds to skin proteins and continues working for hours after each application), spray format that allows no-touch application to painful lesions, a leave-on formula that does not require rinsing, and dual-action coverage that addresses the bacterial primary infection and any yeast co-infection.

The FDA registration and clearly disclosed ingredient concentrations mean you know exactly what you are applying to your dog's skin, which is important for an active, open skin lesion like a hot spot.

Best for itch relief during healing: Vetified Itchy Skin Relief Spray

Active ingredient: 1% Pramoxine HCl

Size: 8 fl oz, FDA-registered

Hot spot treatment is a two-part problem: you need to kill the bacteria (the Chlorhexidine Spray handles this), and you need to stop the itching that caused the hot spot and that continues to drive the scratch-lick cycle during healing. This is where the Vetified Itchy Skin Relief Spray plays a critical complementary role.

Pramoxine hydrochloride is a topical anesthetic that works by blocking nerve signal transmission at the skin's surface. It numbs the itch sensation without using steroids, which is important because topical steroids on an active bacterial infection can actually impair healing by suppressing the local immune response. Pramoxine provides fast-acting itch relief (typically within minutes) that lasts for several hours, giving the skin a window to heal without being scratched or licked.

How to use both sprays together: Apply the Chlorhexidine Spray first and allow it to dry for 5 to 10 minutes. Then apply the Itchy Skin Relief Spray over and slightly beyond the treated area. The chlorhexidine handles the infection while the pramoxine handles the itch. This combination approach addresses both halves of the hot spot problem.

How the top sprays compare for hot spot treatment

A note on "natural" hot spot sprays: Products like Burt's Bees and Vet's Best contain soothing botanical ingredients but lack pharmaceutical-grade antimicrobial agents. While they may provide some comfort and relief for very minor skin irritation, they are not adequate treatment for an established hot spot, which is an active bacterial infection. An established hot spot requires an antiseptic with proven bactericidal activity, such as chlorhexidine gluconate. Using a soothing-only spray on a bacterial lesion allows the infection to spread while providing a false sense of treatment.

Complete Treatment Timeline for Lab Hot Spots

Knowing what to expect during treatment helps you gauge whether healing is on track or whether veterinary intervention is needed.

If the hot spot is not improving by Day 3 (still expanding, still oozing heavily, getting more painful), stop home treatment and see your veterinarian. The lesion may be deeper than a surface hot spot, the bacteria may require systemic antibiotics, or there may be a deeper issue (like a foreign body or abscess) that topical treatment cannot address.

When Home Treatment Is Not Enough: Vet Visit Red Flags

Home treatment is appropriate for small to moderate hot spots that are caught early. However, some situations require professional veterinary care:

• The hot spot is larger than your palm or covers a significant area
• The lesion is deep, with tissue extending below the skin surface (this may be a deep pyoderma rather than a surface hot spot)
• Your Lab is in severe pain and will not let you clip, clean, or treat the area
• No improvement after 48 to 72 hours of consistent home treatment
• The hot spot is spreading despite treatment
• Multiple hot spots are appearing simultaneously (suggests a systemic trigger like severe allergies)
• There is significant swelling around the hot spot (may indicate deeper tissue involvement or abscess)
• Your Lab has a fever, lethargy, or appetite loss (suggests systemic infection)
• The hot spot is near the eye and may be affecting ocular health
• Your Lab gets hot spots repeatedly (every few weeks or months), which suggests an unaddressed underlying trigger

Your vet may prescribe oral antibiotics for deeper or more extensive infections, perform a culture and sensitivity test to identify the specific bacteria and most effective antibiotic, prescribe a short course of oral anti-itch medication (Apoquel, Cytopoint injection, or a short steroid course) to break the scratch cycle, investigate and treat the underlying trigger (allergy testing, flea control audit, ear infection treatment), or sedate your dog to properly clip, clean, and treat a very painful lesion.

Preventing Hot Spots in Labradors: A Breed-Specific Approach

Treating a hot spot solves the immediate problem, but the real goal is reducing how often they occur. For Labradors, prevention centers on managing the breed-specific risk factors we discussed earlier.

Dry your Lab thoroughly after every swim or bath

This is the single highest-impact prevention measure for most Labs. After swimming, bathing, or getting soaked in rain, dry your Lab's coat as thoroughly as possible. Use a high-velocity pet dryer or a regular towel-dry followed by a blow dryer on a cool or warm (never hot) setting. Pay special attention to the areas where hot spots most commonly develop: behind the ears, the neck and rump, the flanks, and the base of the tail. The undercoat is the problem area, so surface-drying alone is not enough. Work the dryer or towel down through the coat to reach the skin level. If complete drying is not possible (for instance, at a lake with no dryer), at minimum towel-dry as thoroughly as you can and keep your Lab in a well-ventilated area (not a crate or car) until the coat is fully dry.

Maintain rigorous flea and tick prevention

A single flea bite can trigger a hot spot in a flea-allergic Lab. Use a veterinarian-recommended flea and tick preventative year-round (not just seasonally), especially if your Lab spends time outdoors in areas with flea and tick populations. If your current preventative allows breakthrough bites, discuss alternatives with your vet. The most effective products currently include isoxazoline-class oral preventatives (Simparica Trio, NexGard, Bravecto), which kill fleas and ticks within hours of attachment before they can trigger a significant skin reaction.

Manage underlying allergies

If your Lab has atopic dermatitis (environmental allergies), managing the allergies reduces the baseline level of skin itching and inflammation, which directly reduces the frequency of hot spot triggers. Allergy management options include immunotherapy (allergy shots or sublingual drops, the only treatment that addresses the root cause), Cytopoint injections (monthly injectable that blocks the itch signal), Apoquel (daily oral medication that controls allergic itch), and environmental allergen reduction measures. Working with a veterinary dermatologist can help develop a long-term allergy management plan tailored to your Lab. For a deeper look at how these medications compare, see our article on why Labradors are so itchy.

Regular grooming and coat maintenance

Regular brushing with an undercoat rake or de-shedding tool removes loose undercoat fur that can mat and trap moisture against the skin. During heavy shedding seasons (spring and fall), daily brushing is ideal. At other times, thorough brushing 2 to 3 times weekly helps maintain good coat condition and airflow to the skin. Never shave a Labrador's coat, as the double coat provides UV protection and insulation that is important for skin health. Instead, focus on removing loose undercoat while keeping the outer coat intact.

Treat ear infections promptly

Given the strong connection between ear infections and hot spots in Labs (the dog scratches at the itchy ear and creates a hot spot on the surrounding skin), treating ear infections early and thoroughly reduces hot spot frequency. Check your Lab's ears weekly for signs of infection: redness, odor, discharge, head shaking, or scratching. Dry the ears after swimming. For Labs with recurring ear issues, see our guide on Labrador ear infections and consider using Vetified's Ear Cleaner for routine ear maintenance after swimming or bathing.

Hot spot-prone areas: proactive spot treatment

If your Lab gets hot spots repeatedly in the same location (common behind the ears, on the rump, or on the flanks), consider proactive spot treatment with an antiseptic spray after swimming or rainy walks. A quick spray of Vetified Chlorhexidine Spray on the hot spot-prone area after it gets wet can help prevent bacterial overgrowth before it starts. This is especially valuable during hot, humid summer months when hot spots are most common.

Common Hot Spot Treatment Mistakes Lab Owners Make

Avoiding these common mistakes can make the difference between a hot spot that resolves in a week and one that lingers for weeks or requires expensive veterinary treatment.

Mistake 1: Not clipping the fur

Applying spray on top of fur does almost nothing. The medication needs direct contact with the skin surface. The matted, wet fur trapping moisture against the lesion also needs to be removed for healing to begin. Yes, it creates a visible bald patch, but the fur grows back. The infection will not resolve itself.

Mistake 2: Bandaging or covering the hot spot

It seems intuitive to cover a wound, but hot spots heal better with air exposure. Bandaging traps moisture and heat against the lesion, creating the same conditions that caused the infection. Keep the area open and exposed to air. Use an E-collar to prevent licking rather than a bandage to cover the area.

Mistake 3: Using hydrogen peroxide or rubbing alcohol

Both are overly harsh on damaged skin. Hydrogen peroxide is cytotoxic (it kills healthy cells along with bacteria) and actually delays wound healing. Rubbing alcohol causes intense stinging pain on raw skin and can cause chemical irritation. Chlorhexidine is the preferred antiseptic because it is effective against bacteria while being gentle on tissue and promoting rather than hindering healing.

Mistake 4: Allowing continued licking

Your Lab's mouth harbors bacteria that will reinfect the hot spot with every lick. The moisture from saliva maintains the wet environment that bacteria thrive in. And the physical trauma of licking extends the skin damage. An E-collar is uncomfortable and inconvenient, but without it, most Labs will lick the lesion relentlessly and undo your treatment efforts.

Mistake 5: Stopping treatment when it looks better

A hot spot that looks "almost healed" still has bacteria on the surface. Stopping treatment at this stage frequently leads to recurrence within days. Continue antiseptic spray treatment until the area is completely dry, the scab has naturally fallen off, new healthy skin is visible underneath, and there is no remaining redness, moisture, or sensitivity. This typically takes 7 to 14 days for a moderate hot spot.

Mistake 6: Not investigating the underlying cause

Treating the hot spot without addressing what triggered it means you are likely to be treating another one within weeks. Every hot spot has a trigger: a flea bite, an itchy ear, an allergic reaction, trapped moisture. If your Lab gets more than one or two hot spots per year, work with your veterinarian to identify and manage the underlying trigger. This is especially important for allergic Labs, where controlling the allergy is the key to controlling the hot spots.

Seasonal Hot Spot Prevention Calendar for Lab Owners

Hot spots have a strong seasonal pattern, especially in Labradors. Here is a practical seasonal approach to prevention.

Spring (March through May)

Hot spot risk begins to climb as temperatures and humidity increase. Environmental allergens (pollen, mold) begin triggering allergy flares in susceptible Labs. Increase brushing frequency to daily as the spring shed begins. Ensure flea prevention is current. Begin ear maintenance routine if your Lab will be swimming. This is a good time for an allergy check-up with your vet if your Lab has a history of seasonal skin problems.

Summer (June through August)

This is peak hot spot season for Labradors. Heat, humidity, swimming, and maximum insect exposure combine for the highest risk period. Dry your Lab thoroughly after every water exposure (swimming, sprinklers, rain). Consider proactive antiseptic spraying of hot spot-prone areas after swimming. Check your Lab's coat daily for any signs of matting, moisture retention, or early skin irritation. Keep allergy medications consistent. Do not skip flea prevention doses. Watch for signs of ear infection, which peak during swimming season.

Fall (September through November)

Hot spot risk decreases as temperatures drop, but the fall shed creates heavy undercoat buildup that can trap moisture. Continue regular brushing. Fall weed pollens and mold spores can trigger allergy flares and secondary hot spots in allergic Labs. Monitor for late-season fleas, which remain active until the first hard frost.

Winter (December through February)

Hot spots are least common in winter, but they can still occur, especially in Labs that are frequently bathed or who live in heated, dry indoor environments that can cause skin irritation and scratching. Indoor allergens (dust mites, mold) can trigger allergy flares year-round. Continue regular brushing and flea prevention even in winter months.

Frequently Asked Questions

Q: Why does my Labrador get hot spots so often?

Labradors are predisposed to hot spots due to a combination of breed-specific factors. Their dense double coat traps moisture against the skin (especially after swimming), they have high rates of environmental allergies that cause baseline skin itching, their active outdoor lifestyle increases exposure to fleas and insect bites, and their floppy ears are prone to infections that cause scratching. If your Lab gets hot spots frequently (more than once or twice per year), the most common underlying drivers are unmanaged environmental allergies, inadequate flea prevention, or a pattern of inadequate coat drying after water exposure. Working with your veterinarian to identify and address the root trigger is the most effective way to reduce frequency.

Q: Can I treat my Lab's hot spot without going to the vet?

Small to moderate hot spots that are caught early can often be successfully treated at home. The key steps are clipping the fur around the lesion, cleaning gently, applying an antiseptic spray (chlorhexidine-based is recommended), and preventing licking with an E-collar. If you follow this protocol consistently and see improvement within 24 to 48 hours, home treatment is likely working. However, you should see a vet if the hot spot is very large, very deep, very painful, not improving after 48 to 72 hours of home treatment, or if your Lab has multiple hot spots or systemic signs like lethargy or fever.

Q: Should I use hydrocortisone or chlorhexidine spray on my Lab's hot spot?

Chlorhexidine is the better first-line choice for hot spots. Hot spots are bacterial infections, and chlorhexidine directly kills the bacteria causing the lesion. Hydrocortisone is a topical steroid that reduces inflammation and itch but does not have antimicrobial activity, meaning it does not address the infection itself. Additionally, applying steroids to an active bacterial infection can actually impair the local immune response and slow healing. If itch relief is needed during treatment, a non-steroidal option like pramoxine HCl is preferable because it numbs the itch without suppressing the immune response. Use chlorhexidine first to treat the infection, and add pramoxine for itch relief as needed.

Q: How long does it take for a hot spot to heal on a Labrador?

With proper treatment (clipping, cleaning, antiseptic spray, and E-collar to prevent licking), most hot spots show significant improvement within 2 to 3 days and are largely healed within 7 to 14 days. Full fur regrowth over the area takes an additional 3 to 6 weeks. The timeline depends heavily on how early the hot spot is caught. A small, early-stage hot spot treated immediately may resolve in under a week. A large, deeply infected hot spot that was developing for days before treatment may take 2 to 3 weeks and potentially require veterinary-prescribed oral antibiotics in addition to topical care.

Q: Can I prevent hot spots if my Lab loves swimming?

You do not have to stop your Lab from swimming, but you do need to actively manage the moisture. The most important preventive step is thorough drying after every swim, using a high-velocity pet dryer or thorough towel-drying that reaches down to the skin through the undercoat. Focus on high-risk areas: behind the ears, the neck, the rump, and the flanks. If your Lab gets hot spots in the same location repeatedly, proactive antiseptic spraying of that area after swimming can help prevent bacterial overgrowth. Regular brushing to remove loose undercoat, up-to-date flea prevention, and management of any underlying allergies also significantly reduce the risk.

Q: Is a hot spot the same thing as a regular skin infection?

A hot spot (acute moist dermatitis) is a specific type of bacterial skin infection characterized by its rapid onset, moist surface, well-defined borders, and self-traumatic origin (the dog's own scratching or licking initiated it). Unlike pyoderma, which develops from bacterial overgrowth on compromised skin, hot spots have an acute, rapid onset and are driven by a cycle of itch, self-trauma, and secondary bacterial infection. The treatment principles overlap with other bacterial skin infections (antiseptic treatment, preventing further contamination), but the critical additional step in hot spot treatment is breaking the itch-scratch cycle that caused and perpetuates the lesion.
