What Are Hot Spots in Dogs?
Hot spots in dogs, also called acute moist dermatitis or pyotraumatic dermatitis, are painful, inflamed patches of skin that can appear suddenly and spread quickly. They often develop when a dog repeatedly scratches, licks or chews an itchy area, damaging the skin and allowing bacteria to multiply. Hot spots typically look red, wet or oozing and may cause hair loss, an unpleasant odor or significant discomfort. Common triggers include flea bites, allergies, ear infections, insect bites, matted fur and moisture trapped against the skin after swimming or bathing. Although they can occur anywhere on the body, hot spots often affect the head, neck, hips and legs. Treatment focuses on stopping further licking or scratching, gently cleaning the area, managing infection or inflammation when present and addressing the underlying trigger to reduce recurrence.
Types
Dogs can develop different types of hot spots, and each can affect the skin in different ways. Some begin around the ears, neck, chest, or hips, while others may spread from one area to another. Understanding the most common types can help pet parents recognize why symptoms, treatment options, and prognosis can vary so widely.
Flea-Related Hot Spots
Develop when flea bites trigger intense itching, causing repeated scratching, licking or chewing that damages the skin.
Environmental Allergy-Related Hot Spots
Caused by excessive scratching or licking associated with allergies to pollen, grass, dust mites or other environmental allergens.
Food Allergy-Related Hot Spots
Can develop when an underlying food allergy causes persistent skin itching, leading to excessive licking, chewing and irritation.
Ear Infection-Related Hot Spots
Often appear near the ears, cheeks or neck when ear infections cause frequent scratching, rubbing or head shaking.
Moisture-Related Hot Spots
Develop when moisture remains trapped against the skin after swimming, bathing or exposure to humid conditions.
Matted Coat-Related Hot Spots
Occur when tangled or dense fur traps moisture and irritants against the skin, contributing to inflammation and itching.
Insect Bite-Related Hot Spots
Develop after insect bites cause localized itching or irritation, prompting dogs to repeatedly scratch or chew the affected area.
Anal Gland-Related Hot Spots
May develop around the tail base or hindquarters when anal gland discomfort causes persistent licking, chewing or rubbing.
Friction or Skin Injury-Related Hot Spots
Can develop after minor scratches, grooming irritation or repeated rubbing damages the skin and triggers excessive licking.
Other Hot Spot Triggers
Includes skin parasites, underlying pain, persistent licking and other conditions that cause repeated skin irritation.
Predisposed Dog Breeds
While hot spots can affect any dog, certain breeds are more prone to developing them. Factors such as thick coats, skin allergies, trapped moisture, and inherited skin sensitivities make some breeds more susceptible to hot spots than others.
| Size / Group | Breeds | Notes on Risk Factors |
|---|---|---|
| Large & Giant Breeds | Golden Retriever, Labrador Retriever, Newfoundland, Saint Bernard, Bernese Mountain Dog | Thick coats and dense undercoats can trap moisture against the skin, increasing the likelihood of irritation and hot spots, especially after swimming or bathing. |
| Medium & Large Breeds | German Shepherd, Rottweiler, Collie, Akita | Dense coats and underlying skin sensitivities can contribute to hot spots. Allergies, flea bites and excessive scratching may further increase the risk. |
| Small & Medium Breeds | Cocker Spaniel, English Springer Spaniel, Beagle, Basset Hound | Breeds with floppy ears may experience ear irritation or infections that trigger scratching around the head, neck and ears, potentially leading to hot spots. |
| Toy & Small Breeds | Shih Tzu, Maltese, Yorkshire Terrier, Miniature Poodle | Long or easily matted coats can retain moisture and irritate the skin. Although these breeds are not necessarily at higher overall risk, allergies and poor coat maintenance can contribute to hot spots. |
| Working & Herding Breeds | Rough Collie, Siberian Husky, Alaskan Malamute, German Shepherd | Heavy double coats can retain moisture and make irritated areas harder to detect. Inadequate drying, matted fur and underlying itching may contribute to hot spot development. |
| Other Susceptible Breeds | English Bulldog, West Highland White Terrier, Rottweiler, Newfoundland | Skin allergies, dense coats or skin folds may contribute to irritation and repeated licking or scratching. Individual skin health and environmental conditions strongly influence hot spot risk. |
Causes
Hot spots in dogs usually develop from a combination of skin irritation, allergies, parasites, trapped moisture, and excessive licking or scratching rather than a single cause. While not all hot spots can be completely prevented, understanding the factors that may increase risk can help pet parents make informed decisions about grooming, skin care, and early detection.
Allergies
Environmental allergens, food allergies, and flea allergy dermatitis can cause intense itching, leading to excessive scratching, licking, and skin damage.
Fleas & Other Parasites
Flea bites, mites, and other external parasites can trigger severe itching and irritation, causing dogs to scratch or chew their skin repeatedly.
Ear Infections
Painful or itchy ear infections can cause frequent scratching and head shaking, sometimes leading to hot spots around the ears, cheeks, and neck.
Trapped Moisture
Moisture left on the skin after swimming, bathing, or exposure to humid conditions can contribute to irritation, especially beneath thick or dense coats.
Matted or Dense Coats
Thick fur and matted hair can trap moisture, dirt, and irritants against the skin, increasing discomfort and creating conditions that favor hot spot development.
Insect Bites & Skin Injuries
Insect bites, minor wounds, scratches, or friction can irritate the skin and trigger repeated licking or chewing, allowing hot spots to develop rapidly.
Underlying Pain or Discomfort
Anal gland problems, joint pain, or other sources of discomfort may cause persistent licking or chewing of one area, eventually damaging the skin and contributing to hot spots.
Symptoms
Hot spot symptoms in dogs can vary depending on the location, size, and severity of the skin irritation. Some signs may be subtle at first, while others can become more noticeable as the condition progresses. Common warning signs include red, inflamed skin, moist or oozing sores, hair loss, excessive licking or scratching, swelling, unpleasant odor, and pain or tenderness. Because many of these symptoms can also be caused by other skin conditions, any persistent or unusual changes should be evaluated by a veterinarian.
- Red, inflamed patches of skin
- Moist, oozing, or weeping sores
- Excessive scratching or itching
- Frequent licking, biting, or chewing
- Hair loss around affected areas
- Swelling and skin tenderness
- Warm or painful skin lesions
- Unpleasant odor from affected skin
- Matted or sticky fur around sores
- Rapid enlargement of irritated patches
Hot spots can develop anywhere on a dog’s skin.
Stages & Progression of Hot Spots in Dogs
Hot spots in dogs can progress at different rates depending on the underlying cause, location, severity of skin irritation, and whether the affected area continues to be scratched or licked. Understanding how advanced a hot spot has become helps veterinarians determine the extent of skin damage, whether infection is present, and which treatment options may be most appropriate. Recognizing the progression of hot spots can also provide important insight into healing time, potential complications, and the level of care your dog may need.
Initial Irritation
Allergies, flea bites, trapped moisture, or other triggers cause itching and mild skin irritation, prompting the dog to scratch or lick.
Skin Damage
Repeated scratching, licking, or chewing damages the skin’s protective barrier, causing redness, inflammation, and increasing discomfort.
Active Hot Spot
A painful, moist, inflamed lesion develops, often accompanied by hair loss, oozing, bacterial overgrowth, and persistent itching.
Worsening Inflammation
Without treatment, the affected area may expand rapidly, causing increased pain, swelling, discharge, and possible secondary complications.
This chart is a simplified visual guide, not a formal veterinary staging system. Hot spots can develop or worsen within hours, and not every case follows these phases. Prompt veterinary care, prevention of further licking, and treatment of the underlying cause can help limit skin damage and support healing.
Top Ways to Prevent Hot Spots in Dogs
Because hot spots are a common skin condition often triggered by allergies, parasites, moisture, and excessive scratching, early prevention and proper skin care are essential. By maintaining regular grooming, keeping your dog’s coat clean and dry, preventing fleas, and addressing skin irritation promptly, the risk of hot spots can be significantly reduced. Proactive care helps detect issues early, improving your dog’s skin health and overall comfort.
| Prevention Strategy | Why It Helps | How to Do It |
|---|---|---|
| Maintain Regular Grooming | Regular grooming helps prevent matted fur, trapped moisture, and skin irritation that can contribute to hot spot development. | Brush your dog’s coat regularly, remove loose hair and tangles, and schedule professional grooming when needed, especially for long-haired or thick-coated breeds. |
| Keep the Coat Clean & Dry | Excess moisture trapped against the skin can encourage irritation and bacterial overgrowth, increasing the likelihood of hot spots. | Thoroughly dry your dog after swimming, bathing, or getting wet. Pay special attention to dense undercoats, skin folds, and areas behind the ears. |
| Prevent Fleas & Other Parasites | Flea bites and other parasites can trigger intense itching, leading to repeated scratching, chewing, and skin damage. | Use veterinarian-recommended flea and parasite preventives, check your dog’s coat regularly, and maintain a clean living environment to reduce exposure. |
| Manage Skin Allergies | Environmental and food allergies can cause persistent itching and inflammation, making dogs more susceptible to recurring hot spots. | Work with your veterinarian to identify allergy triggers, follow prescribed treatments, and monitor your dog for seasonal or recurring skin irritation. |
| Check & Care for the Ears | Ear infections and irritation can cause excessive scratching and head shaking, potentially leading to hot spots around the ears, cheeks, and neck. | Inspect your dog’s ears regularly, keep them dry, and use veterinarian-approved ear cleaners when recommended. Seek treatment for redness, odor, or discharge. |
| Prevent Excessive Licking & Scratching | Repeated licking, biting, and scratching damage the skin’s protective barrier and can rapidly worsen minor irritation into painful hot spots. | Address the underlying cause of itching promptly. Use a protective e-collar if recommended by your veterinarian to prevent further skin damage. |
| Schedule Regular Veterinary Checkups | Routine examinations can help identify underlying allergies, ear infections, parasites, or other skin problems before they contribute to recurring hot spots. | Schedule routine veterinary visits and discuss persistent itching, skin sensitivities, or previous hot spot episodes with your veterinarian. |
| Monitor for Early Signs | Recognizing skin irritation early allows for faster treatment and may prevent small affected areas from developing into larger, painful lesions. | Check for redness, moist patches, hair loss, excessive licking, or unusual odors. Contact your veterinarian promptly if a hot spot develops or spreads. |
Actionable Resources
If you want to prevent or reduce the recurrence of hot spots in your dog, here are some things you can do under veterinary guidance.
How Are Hot Spots in Dogs Diagnosed
Diagnosing hot spots in dogs requires a veterinary evaluation to determine the underlying cause, severity, and extent of the skin irritation. Key steps include:
1. Physical Examination
Your veterinarian examines the affected skin for redness, moisture, inflammation, hair loss, and painful lesions. Hot spots are often diagnosed based on their characteristic appearance and a physical examination.
2. Medical History
Your veterinarian reviews your dog’s history of allergies, flea exposure, grooming, swimming, ear infections, and previous skin problems to identify possible triggers contributing to hot spot development.
3. Skin Assessment
The affected area is evaluated for its size, severity, discharge, and surrounding skin damage. Fur may be carefully clipped to expose the lesion and determine the full extent of the irritation.
4. Skin Cytology
If needed, your veterinarian collects surface cells using a swab or impression smear to examine under a microscope. This helps identify bacteria, yeast, and inflammatory cells associated with the lesion.
5. Additional Skin Tests
Flea checks, skin scrapings, bacterial cultures, or other tests may be recommended if parasites, unusual infections, or recurring skin problems are suspected. Most uncomplicated hot spots do not require extensive testing.
6. Underlying Cause Evaluation
Your veterinarian investigates potential underlying causes such as allergies, ear infections, parasites, or trapped moisture. Identifying and managing these triggers helps guide treatment and reduce the risk of recurring hot spots.
Early detection is vital because hot spots can spread rapidly if left untreated—allowing for more effective management, faster healing, and improved comfort for your dog.
Nutritional Support & Supplements
Proper nutrition can play an important supportive role for dogs with hot spots by helping maintain healthy skin, coat condition, immune function, and overall well-being during recovery. Depending on your dog’s needs, veterinarians may recommend strategies such as complete and balanced diets, omega-3 fatty acids, or specialized diets for dogs with confirmed food allergies. These nutritional approaches may support skin health but should complement, not replace, veterinary treatment of hot spots and their underlying causes.
Important: Nutrition can support skin health but does not replace veterinary treatment for hot spots. Supplements may interact with medications, and excessive amounts of certain nutrients, including zinc and vitamins, can be harmful.
Always consult your veterinarian before changing your dog’s diet or adding supplements, especially if your dog has recurring hot spots or suspected food allergies.
Supportive care—such as pain management, proper skin care, nutritional support, and grooming adjustments—plays a crucial role in maintaining comfort and promoting healing during treatment. These measures are not a cure for hot spots and may not address underlying causes such as allergies or infections, so any skin care products, medications, diet changes, or supplements should be reviewed with your veterinarian.

Treatment & Care
According to current veterinary dermatology practices, the most effective treatments for hot spots in dogs are multimodal, combining several approaches for the best outcome. These may include clipping the surrounding fur and gently cleaning the affected skin, topical or oral medications to control inflammation and infection when needed, and protective collars to prevent further licking or scratching. Addressing underlying causes such as allergies, fleas, or ear infections is also essential to promote healing and prevent recurrence.
Medications
Common medications used to treat hot spots in dogs include:
| Medication / Class | Examples | How It Is Used | Important Considerations |
|---|---|---|---|
| Topical Antiseptics | Chlorhexidine-based cleansers, veterinarian-recommended antiseptic sprays | Used to gently clean the affected skin, reduce surface bacteria, and help prepare the area for healing after the surrounding fur is clipped. | Products should be veterinarian-approved for dogs. Some products may sting on open or very inflamed skin, and overuse can further irritate sensitive areas. |
| Topical Antibiotics | Mupirocin, fusidic acid, other veterinarian-prescribed antibiotic creams or sprays | May be used on localized hot spots when bacterial infection is suspected or confirmed. | Should only be used under veterinary guidance. Dogs may try to lick treated areas, so an e-collar or supervision may be needed. |
| Topical Corticosteroids | Hydrocortisone-containing veterinary products, combination steroid sprays | Used to reduce itching, inflammation, and redness in selected cases of hot spots. | Not appropriate for every lesion. Overuse may delay healing or worsen certain infections, so these products should be used only as directed by a veterinarian. |
| Systemic Antibiotics | Cephalexin, amoxicillin-clavulanate, clindamycin | Oral antibiotics may be prescribed for deeper, widespread, or severe skin infections associated with hot spots. | Full treatment courses should be completed as prescribed. These drugs may cause gastrointestinal upset in some dogs. |
| Systemic Corticosteroids | Prednisone, prednisolone | May be used short-term to quickly reduce severe itching and inflammation, especially when a dog is actively scratching or chewing the area. | Can cause increased thirst, urination, appetite, and other side effects. These medications should only be used under veterinary supervision and may not be appropriate in every case. |
| Anti-Itch / Allergy Medications | Oclacitinib, lokivetmab, antihistamines selected by a veterinarian | Used when allergies or chronic itching are contributing to hot spot formation or recurrence. | These medications help control the underlying itch but do not replace cleaning and direct treatment of the hot spot itself. |
| Pain Relief / Anti-Inflammatory Support | Veterinarian-prescribed analgesics, selected NSAIDs when appropriate | May be used to improve comfort in dogs with painful, inflamed, or extensive skin lesions. | Pain medications should only be used under veterinary supervision. Human pain relievers should never be given unless specifically directed by a veterinarian. |
| Ear Medications | Veterinarian-prescribed ear cleaners, antifungal or antibiotic ear drops | Used when ear infections or ear irritation are the underlying trigger for hot spots around the head, cheeks, or neck. | Treating the hot spot alone may not prevent recurrence if the ear problem is not addressed at the same time. |
| Flea Control Products | Isoxazoline products, veterinarian-recommended flea preventives | Used when flea bites or flea allergy dermatitis are causing intense itching and contributing to hot spots. | Effective flea control is essential in dogs with flea-related skin disease. Product choice should be based on veterinary advice and the dog’s health history. |
| Protective Devices | Elizabethan collar, inflatable recovery collar, protective clothing | Used to stop licking, biting, and scratching so the skin can heal and topical treatments can work effectively. | These are not medications, but they are often a crucial part of treatment because ongoing self-trauma can quickly worsen a hot spot. |

Alternative & Integrative Therapies
Integrative and supportive therapies can help manage itching, reduce discomfort, and promote skin healing for dogs with hot spots. Options such as cool compresses, gentle skin cleansing, omega-3 fatty acids, and protective collars may be used alongside conventional treatment, but should always be discussed with your veterinarian to ensure they are safe and appropriate for your dog.
Surgical Options
Surgery is rarely necessary for hot spots in dogs, as most cases can be effectively managed with proper skin care and veterinary treatment. Depending on the severity and location of the affected area, treatment may involve clipping the surrounding fur, cleaning the infected skin, removing damaged tissue when necessary, relieving pain and inflammation, or preventing further irritation. Some dogs with severe or complicated infections may require sedation for thorough wound cleaning or surgical drainage of an underlying abscess. Your veterinarian will determine whether additional procedures are appropriate based on the lesion’s size, severity, location, and your dog’s overall health.
Emotional & Lifestyle Impact
Hot spots can be uncomfortable and stressful for both dogs and their families. Dogs may experience changes in energy, appetite, sleep, and behavior due to persistent itching, pain, and skin irritation, while some treatments may require temporary adjustments to grooming and daily activities. With proper care and support, most dogs can recover comfortably and return to their normal, happy routines.
For Dogs
