Preventing Dog Hot Spots Before They Start

icon Last Updated September 10, 2025

Dog owners know the frustration of seeing their furry friend scratch, bite, or lick at a patch of irritated skin. These areas, known as hot spots or acute moist dermatitis, are not only painful for your dog but can quickly become infected if left untreated. While treatments exist, the best approach is prevention. In this comprehensive guide, we’ll explore in depth how to prevent hot spots on dogs before they start.

What Are Dog Hot Spots?

Dog hot spots are inflamed, infected areas of skin that develop rapidly. They are typically red, moist, and itchy, and dogs often obsessively lick or bite them. While hot spots can affect any breed, dogs with thick fur, floppy ears, or allergies are particularly prone.

Common Symptoms of Hot Spots

  • Red, inflamed skin

  • Moist, oozing patches

  • Hair loss around the affected area

  • Intense itching, licking, or biting

  • Foul odor in severe cases

Understanding why hot spots form is the first step in preventing them.

Causes of Hot Spots in Dogs

Hot spots can develop for a variety of reasons, often as a reaction to underlying issues:

1. Allergies

Dogs can be allergic to environmental factors such as pollen, dust, or mold, as well as food allergies. Allergies can cause persistent scratching, which breaks the skin and leads to hot spots.

2. Fleas and Parasites

Flea infestations are a primary trigger. Dogs may scratch or bite at the irritation, creating the perfect environment for a hot spot. Other parasites, like mites or ticks, can also contribute.

3. Skin Infections

Bacterial or fungal infections may arise when the skin barrier is weakened. Once a dog begins licking or chewing at an itchy spot, bacteria multiply, causing a hot spot.

4. Moisture and Humidity

Dogs with thick coats or long hair are more prone to moisture retention, especially after swimming or bathing. Moist environments breed bacteria and increase hot spot risk.

5. Stress and Anxiety

Dogs can develop hot spots as a form of compulsive behavior, often due to anxiety, boredom, or stress.

6. Poor Grooming

Matted fur traps dirt, moisture, and bacteria against the skin, making certain dogs more susceptible to hot spots.

Identifying Early Signs of Hot Spots

Early intervention can prevent small irritations from turning into severe hot spots. Watch for:

  • Excessive licking or scratching at one area

  • Patchy hair loss

  • Redness or raised skin

  • Mild oozing or crust formation

By catching hot spots early, you can prevent infection and reduce your dog’s discomfort.

Preventing Hot Spots Before They Start: Key Strategies

Prevention is better than cure. Here’s how to protect your dog from hot spots before they start:

1. Regular Grooming

Keeping your dog clean and well-groomed is the first line of defense.

Tips:

  • Brush your dog’s coat regularly to remove mats and tangles.

  • Bathe your dog with hypoallergenic shampoos to reduce skin irritation.

3. Maintain a Healthy Diet

A well-balanced diet supports healthy skin and coat, reducing hot spot susceptibility:

  • Include omega-3 fatty acids to reduce inflammation.

  • Avoid allergens that trigger reactions in sensitive dogs.

  • Consult your vet for diet recommendations if your dog has a history of skin issues.

4. Drying Your Dog Thoroughly

Moisture can lead to hot spots quickly:

  • Dry your dog completely after bathing or swimming.

  • Pay extra attention to thick fur or folds in the skin.

  • Consider a blow dryer on a cool setting for longer-haired breeds.

5. Stress and Behavioral Management

Anxiety can trigger compulsive licking:

  • Provide plenty of mental stimulation, such as puzzle toys or training sessions.

  • Ensure your dog has a safe, comfortable space to relax.

  • Consult a professional if your dog shows signs of chronic anxiety or obsessive behavior.

6. Early Intervention for Minor Irritations

Even minor scratches or insect bites can escalate into hot spots:

  • Clean and disinfect small wounds immediately.

  • Apply a vet-approved topical antiseptic.

  • Monitor for signs of infection or persistent licking.

Breed-Specific Considerations

Certain breeds are more prone to hot spots due to skin type, coat density, or ear structure.

  • Golden Retrievers and Labs: Thick undercoats trap moisture.

  • German Shepherds: Skin folds and allergies increase risk.

  • Saint Bernards, Bulldogs, and Other Floppy-Eared Breeds: Moist ears can lead to hot spots near the head and neck.

  • Long-Haired Breeds: Hair mats can trap dirt and bacteria.

Knowing your dog’s predispositions allows for targeted preventive care.

Home Remedies and Preventive Products

Several products and home practices can help prevent hot spots:

1. Anti-Itch Sprays and Creams

Veterinarian-approved sprays can reduce irritation before it escalates.

2. Medicated Shampoos

Shampoos with oatmeal, aloe, or antibacterial agents can soothe skin and prevent bacterial growth.

3. Supplements for Skin Health

  • Omega-3 fatty acids

  • Probiotics for gut health

  • Vitamin E for skin regeneration

4. Protective Clothing

In cases of chronic hot spots, dog shirts or recovery suits can prevent licking and scratching.

Environmental Prevention Tips

Your dog’s environment plays a role in hot spot prevention:

  • Keep bedding clean and dry.

  • Avoid prolonged exposure to humid or wet conditions.

  • Remove potential allergens from the home, such as dust mites or mold.

When to See a Veterinarian

Even with preventive measures, hot spots may still occur. Seek veterinary care if:

  • The hot spot spreads rapidly

  • There is pus, severe odor, or bleeding

  • Your dog shows lethargy or loss of appetite

  • Over-the-counter treatments fail to provide relief

Veterinarians may prescribe:

  • Antibiotics for bacterial infections

  • Anti-inflammatory medications

  • Medicated shampoos or topical ointments

Long-Term Hot Spot Management

For dogs prone to recurring hot spots:

  • Keep a hot spot journal noting triggers, seasonality, and diet changes.

  • Schedule regular vet check-ups to monitor skin health.

  • Adjust grooming frequency according to your dog’s coat type and activity level.
