Summer Hot Spots in Dogs: Causes and Solutions

Hot spots, also known as acute moist dermatitis, are a painful and often sudden skin condition that affects many dogs, especially in the warmer months. Summer hot spots in dogs are particularly common due to a combination of heat, humidity, allergens, parasites, and increased outdoor activity. This comprehensive guide will explore the causes, symptoms, treatment, and prevention of hot spots in dogs during the summer season.

What Are Hot Spots in Dogs?

Hot spots are localized areas of skin inflammation and bacterial infection. They often appear as red, moist, irritated lesions that can quickly become large, oozing sores. Dogs usually exacerbate these spots by licking, chewing, or scratching them, which can worsen the condition.

Common Characteristics of Hot Spots:

• Red, inflamed skin

• Moist, oozing, or pus-filled lesions
  
  

• Hair loss around the area

• Foul odor

• Pain and sensitivity to touch

Hot spots can appear anywhere on a dog's body but are most common on the head, neck, hips, and legs.

Why Summer Increases the Risk of Hot Spots

Summer weather creates the perfect storm for hot spots to develop. Hot spots on dogs start as small scratches or cuts that itch caused by allergies, parasites, etc.. In an attempt to relieve the discomfort, dogs scratch, bite and lick the affected area. However, the more they do this, the larger the spot becomes. Inevitably, a secondary infection (either bacterial or fungal) develops. This makes everything even itchier. This is a cycle that continues indefinitely unless you put a stop to it.  Here's why this cycle may be more prevalent in Summer:

1. Heat and Humidity:
Warm weather combined with high humidity creates a moist environment where bacteria can thrive. Dogs with thick or long coats are especially susceptible as moisture becomes trapped against their skin.

2. Increased Shedding and Matting:
Seasonal shedding and improper grooming during the summer can lead to mats and tangles, which trap moisture and irritants against the skin, creating breeding grounds for bacteria.

3. Parasites:
Fleas, ticks, and mites are more prevalent during summer and can trigger intense itching. Dogs scratch or bite at these bites, damaging their skin and causing hot spots.

4. Allergens:
Environmental allergens such as pollen, grass, and mold increase during summer. Allergic reactions can cause itching and inflammation, prompting dogs to scratch or lick, leading to hot spots.

5. Outdoor Activities:
Swimming, hiking, and increased time outside mean more exposure to irritants like dirt, sand, water, and bites. Moisture from swimming or being wet too long without drying properly can also cause hot spots.

Breeds Prone to Summer Hot Spots

While any dog can get hot spots in Summer, some breeds are more vulnerable, especially those with dense coats, skin folds, or a tendency toward allergies.

High-Risk Breeds:

• Golden Retrievers

• German Shepherds

• Labrador Retrievers

• Saint Bernards

• Newfoundlands

• Bulldogs

• Cocker Spaniels

These breeds often have thick fur or skin folds where moisture and bacteria can build up.

Signs Your Dog Has a Summer Hot Spot

Common summer hot spot areas in dogs include the neck, ears, hips, tail base, groin, belly, and between toes—typically where moisture, friction, or allergens easily get trapped and cause irritation. Check these areas and note any abnormal behaviours, as this is a good way to spot hot spots early, especially in the summer. Being able to recognize the signs early can help you treat a hot spot before it worsens:

• Sudden scratching, licking, or chewing at one area

• Localized hair loss

• Red, raw, or weepy skin

• Swelling or crusting

• A visible sore or wound

• Your dog winces or pulls away when the area is touched

If left untreated, hot spots can grow rapidly and become infected, leading to more serious complications.

Diagnosing Summer Hot Spots

While many hot spots are easy to identify at home, it's important to have a vet confirm the diagnosis. Your vet may:

• Perform a physical examination

• Shave the area to assess the extent of the damage

• Take a skin scraping or swab to check for bacteria, fungi, or parasites

• Ask about your dog’s recent activities, grooming habits, and diet

Treating Summer Hot Spots in Dogs

Treatment involves addressing both the hot spot itself and the underlying cause.

1. Clean and Trim the Area:

• Shave the fur around the hot spot to expose the skin

• Gently clean with an antiseptic solution (e.g., chlorhexidine)

• Pat dry thoroughly

2. Stop the Itching and Infection:

• Apply topical anti-itch spray or anti-inflammatory creams

• In some cases, oral antibiotics and corticosteroids are prescribed

• Use an Elizabethan collar (E-collar) to prevent further licking or scratching

3. Identify and Address the Cause:

• Treat parasites with flea/tick preventatives
  Puainta® Pest Control Collar for Dogs/Cats effectively repels ticks and fleas with a pet-safe formula that reduces anxiety, promotes emotional balance, and alleviates stress-related behaviors.

• Improve grooming practices

4. Monitor and Follow-Up:

• Check the area daily for healing

• Keep the dog dry and cool

• Revisit the vet if the spot worsens or does not heal

Natural Remedies for Mild Hot Spots (With Caution)

For minor hot spots or in early stages, some natural remedies may provide relief:

• Aloe vera gel (pure, without additives)

• Coconut oil as a mild anti-inflammatory

• Chamomile tea compresses to soothe irritation

Always consult your vet before applying anything to your dog’s skin.

Preventing Summer Hot Spots in Dogs

Prevention is the best strategy, especially during hot, humid months.

1. Keep Your Dog Dry:

• Towel dry after swimming or bathing

• Avoid prolonged dampness under collars or harnesses

2. Groom Regularly:

• Brush daily to remove loose fur and prevent matting
  
  

• Trim long coats, especially in high-risk areas

• Consider professional grooming every 6–8 weeks

3. Use Parasite Prevention:

• Apply vet-approved flea and tick preventatives year-round

• Inspect your dog regularly, especially after outdoor play

4. Manage Allergies:

• Use vet-recommended antihistamines or allergy relief

• Wipe paws and coat after outdoor exposure

• Keep your dog indoors on high-pollen days

5. Monitor Behavior:

• Watch for excessive licking or scratching

• Redirect the behavior with toys or gentle training

6. Provide a Cool Environment:

• Ensure access to shade and water

• Avoid overheating during walks or play
  
  

When to See a Veterinarian

You should consult your vet if:

• The hot spot is spreading quickly

• Your dog is in obvious pain or distress

• The area smells foul or leaks pus

• There are signs of systemic illness (fever, lethargy, loss of appetite)

Prompt treatment helps prevent complications like deep skin infections or chronic skin issues.

FAQs

Q: Can dogs get hot spots from swimming?
A: Yes. If a dog stays damp for too long after swimming, especially under collars or in thick fur, it can lead to hot spots.

Q: Are hot spots contagious to humans or other dogs?
A: No. Hot spots themselves are not contagious, though parasites or infections that trigger them may spread.

Q: How fast do hot spots grow?
A: Very fast—they can go from a small red patch to a large, oozing sore in less than 24 hours if not addressed.

Q: Can food allergies cause hot spots?
A: Yes. Dogs with food allergies may develop itchy skin, which can lead to excessive scratching and eventually hot spots.

Q: Should I shave my dog to prevent hot spots in Summer?
A: Not necessarily. Shaving too close can irritate the skin. Regular brushing and professional grooming are better options.
