Hot Spots on Dogs
Hot Spots in Dogs with Long Hair: Why Coat Type Matters
A skin infection known as hot spots, or acute moist dermatitis, is a common complaint among dogs, especially those with long or thick fur. The long hair of some breeds can trap moisture and debris, creating an environment in which bacteria can thrive. This makes them more susceptible to infection.

Hot spots, also known as acute moist dermatitis, are a common but distressing skin issue that many dogs face. These painful, inflamed lesions can appear suddenly and spread rapidly, especially in breeds with long or dense coats. Dogs with long hair are particularly susceptible to hot spots due to the unique challenges their coat type presents. In this comprehensive guide, we will explore the causes, symptoms, and most importantly, the treatment and prevention of hot spots in long-haired dogs.
Understanding Hot Spots in Dogs
Hot spots are localized areas of skin inflammation and bacterial infection. They usually begin as small red patches but can quickly become larger, oozing sores that are painful and itchy. The most common areas affected include the neck, hips, limbs, and base of the tail, though hot spots can occur anywhere on the body.
Common Causes of Hot Spots
-
Allergies (food, environmental, or flea-related)
-
Poor grooming habits
-
Trapped moisture in the coat
-
Excessive licking or scratching
-
Flea infestations
-
Ear or skin infections
-
Matted fur

Why Long-Haired Dogs Are at Higher Risk
Long-haired breeds such as Golden Retrievers, Collies, Shih Tzus, and Bernese Mountain Dogs have thick coats that retain moisture and heat. These conditions are perfect for bacterial growth, which contributes to hot spot formation. Because of their long hair, hot spots on dogs can easily be hidden before they progress.
Key Risk Factors for Long-Haired Breeds:
-
Trapped Moisture: Water from bathing, swimming, or rain can become trapped close to the skin.
-
Matted Fur: Mats can pull on the skin and create irritation that leads to self-trauma.
-
Inadequate Airflow: Dense coats prevent air circulation, creating a warm, moist environment.
-
Delayed Detection: In long-haired dogs, hot spots are harder to see in early stages, allowing them to worsen quickly.
Signs of Hot Spots in Long-Haired Dogs
Identifying hot spots in long-haired breeds can be tricky. Regular inspection is key.
Symptoms to Look For:
-
Red, inflamed skin

-
Oozing or moist lesions
-
Hair loss in the affected area
-
Foul odor
-
Constant licking, biting, or scratching
-
Sensitivity to touch
Diagnosis and When to See a Veterinarian
Although some hot spots can be treated at home, it’s best to consult a veterinarian for accurate diagnosis and care, especially if:
-
The hot spot is rapidly growing
-
There are signs of systemic infection (fever, lethargy)
-
Home treatment hasn’t helped within 48 hours
What to Expect at the Vet:
-
Physical Exam: Visual and tactile inspection of the lesion.
-
Skin Scraping or Culture: To rule out parasites or secondary infection.
-
Medication Prescription: Antibiotics, anti-inflammatories, or medicated shampoos.
Treatment for Hot Spots in Long-Haired Dogs
Treating hot spots in long-haired breeds involves a combination of trimming, cleansing, medication, and behavioral management.
1. Clipping and Cleaning the Area
-
Carefully clip the hair around the hot spot to expose the lesion.
-
Clean the area with a gentle antiseptic solution like chlorhexidine.
-
Pat dry thoroughly to avoid additional moisture retention.
2. Topical Treatments
-
Antibacterial Sprays: E.g., Vetericyn, Betagen
This Puainta® Quantum Silver Antibacterial & Anti-itch Spray is specifically designed to treat hot spot symptoms in dogs and cats, and help soothe red, scaly, greasy, or smelly skin. It deodorizes and helps relieve fungal and bacterial skin infections, relieves itchy skin in cats and dogs, and helps control the spread of lesions.
-
Antiseptic Creams: Like chlorhexidine ointments
-
Soothing Gels: Aloe vera-based, free from alcohol or fragrances
3. Oral Medications (If prescribed)
-
Antibiotics: To treat secondary bacterial infection
-
Steroids: To reduce inflammation and itching
-
Antihistamines: For allergy-related cases
4. Medicated Baths and Shampoos
Use a vet-approved antibacterial or antifungal shampoo, such as:
-
Douxo S3 PYO Shampoo
-
Zymox Enzymatic Shampoo
-
Vet’s Best Hot Spot Shampoo
Important: Always dry the coat thoroughly after bathing. Use a high-velocity dryer on a cool setting to avoid leaving moisture trapped near the skin.
5. E-Collars and Protective Clothing
To prevent licking or scratching during recovery:
-
Elizabethan collars (E-collars)
-
Inflatable collars
-
Dog bodysuits or recovery shirts
6. Regular Grooming
A strict grooming routine is essential:
-
Daily brushing to prevent mats
-
Regular trims, especially in high-risk areas
-
Checking for parasites like fleas and ticks

Lifestyle Adjustments to Aid Recovery
-
Diet: Switch to a hypoallergenic or skin-supportive diet if allergies are suspected.
-
Exercise: Moderate exercise to reduce stress without overexerting.
-
Environment: Maintain a clean, dry living space. Avoid high-humidity areas.
-
Behavioral Enrichment: Reduce anxiety-related licking by providing toys, puzzles, and companionship.

Breed-Specific Concerns

Dense, continuously growing hair
-
Requires professional grooming every 4-6 weeks

Collies & Shetland Sheepdogs

Focus on de-shedding and keeping the undercoat dry
Bernese Mountain Dogs & Newfoundlands

Heavy coats retain moisture
-
Limit swimming or dry thoroughly afterward
Hot Spot Healing Timeline
-
Mild Cases: 3-5 days with home care
-
Moderate Cases: 7-10 days with vet-prescribed treatments
-
Severe Cases: 2+ weeks; may require follow-up visits
Note: Do not stop treatment early even if it looks healed. Always follow the full course of medication.
Common Mistakes When Dealing with Hot Spots to Avoid
-
Ignoring early signs: Early detection prevents escalation.
-
Using human medications: Many are toxic to dogs.
-
Leaving the coat wet: Always dry completely.
-
Letting dogs lick the area: Delays healing and worsens infection.
Conclusion:
Long-haired dogs are beautiful and loving companions, but their luxurious coats come with challenges. Understanding how their coat type contributes to skin issues like hot spots can help you stay proactive in both treatment and prevention. By maintaining a rigorous grooming routine, managing environmental factors, and seeking timely veterinary care, you can ensure your long-haired dog stays comfortable, healthy, and free from the misery of hot spots.
