If you’ve noticed your dog licking or scratching a certain area repeatedly, it’s possible they have a hot spot. Learning what these skin lesions look like can help you take prompt action to alleviate your pet’s discomfort.
Hot Spots on Dogs: What Do They Look Like?
Hot spots on dogs typically appear as red, swollen, moist patches that look raw and inflamed. Medically known as acute moist dermatitis or pyotraumatic dermatitis, their visual appearance is quite distinctive and can be identified relatively easily.
When examining pictures of hot spots on dogs, you’ll notice several primary characteristics: the affected area is bright red with inflamed skin that may appear glistening or wet.
The lesion often has pus or discharge that makes it moist and sticky. Hair loss in the surrounding area is common, exposing the raw damaged skin beneath.
These painful spots may be as small as a quarter or grow large enough to resemble a pancake. Most pet owners report that hot spots appear almost overnight and can spread rapidly within hours if left untreated.
Common Locations for Hot Spots
Visual evidence in pictures of hot spots on dogs shows these lesions most commonly occur in certain body areas:
Head and Neck Region: Hot spots frequently appear on the cheeks, behind the ears, and around the neck. These locations are often associated with ear infections or collar irritation.
Hips and Rump: The area around the tail and tail base is particularly susceptible, especially in dogs with flea allergies. Hot spots in this region are often depicted with significant redness and moisture.
Limbs and Paws: Front legs, paws, and hocks commonly develop hot spots, particularly in dogs experiencing arthritis or other orthopedic issues.
Chest and Belly: Though less frequent, these areas may retain moisture, especially in dogs with skin folds or after swimming.
Identifying Hot Spots Through Visual Symptoms
When examining pictures of hot spots on dogs, watch for these key indicators:
Redness and Inflammation: The skin appears bright red, raised, and swollen compared to surrounding tissue.
Moisture and Discharge: Hot spots are characteristically wet and oozing, with surfaces that may appear shiny with pus or fluid drainage, unlike dry skin conditions.
Hair Loss: The affected region experiences significant fur loss, with hair often matted to the edges of the lesion.
Crusty Scabs: Older hot spots develop dark crusts or scabs as they begin healing, visible in pictures showing healing progression.
Size Variation: Fresh lesions can be small but may rapidly expand within hours.
What Causes Hot Spots in Dogs?

Understanding underlying causes helps prevent future occurrences. Hot spot development is typically a self-inflicted process involving scratching, licking, and biting.
Allergies
Environmental allergens like pollen, molds, dust mites, and food allergies trigger severe itching. Flea allergy dermatitis is particularly problematic, even a single flea bite can cause serious reactions in hypersensitive dogs.
Moisture Accumulation
Dogs with thick, dense coats who swim frequently or live in humid climates are prone to moisture accumulation against the skin. Bacterial growth thrives when dogs aren’t completely dried following baths or rain.
Parasites and Insects
Fleas, ticks, mosquitoes, and mites irritate the skin, causing excessive scratching that ruptures the protective skin barrier.
Ear Infections
Bacterial or yeast infections in the ear canal cause dogs to scratch around the ears and neck vigorously, developing hot spots on the cheeks and neck.
Poor Grooming
Matted fur traps moisture and dirt against the skin. Tangles and knots irritate skin, prompting dogs to bite and chew uncomfortable areas.
Behavioral Factors
Boredom, anxiety, and stress may trigger compulsive licking and chewing. Dogs often focus on easily accessible areas like paws and legs.
Orthopedic Issues
Arthritis and joint pain cause dogs to lick affected areas for relief. Hot spots on hips and elbows in older dogs with reduced mobility may be pressure sores from constant lying.
Breeds Most Susceptible to Hot Spots
Some breeds appear in hot spot pictures more frequently due to their coat characteristics:
- Golden Retrievers
- Labrador Retrievers
- German Shepherds
- Saint Bernards
- Rottweilers
- Newfoundlands
- Collies
- English Bulldogs
These breeds typically have thick, dense coats or skin folds that trap moisture and heat against the skin.
Treating Hot Spots
If you notice symptoms resembling pictures of hot spots on dogs, prompt treatment is essential to prevent complications.
Veterinary Treatment
Your veterinarian will first clip hair around the lesion to expose it to air, an important step enabling proper cleaning and drying. The area is then cleaned with chlorhexidine or other antimicrobial cleansers.
Medications
Topical antiseptics are typically applied directly to the lesion. Current guidelines recommend topical antimicrobial treatment as the first-line management for hot spots.
Severe infections may require oral antibiotics, typically for 7-14 days. Anti-inflammatory medications like NSAIDs or steroids help reduce itching and pain.
Preventing Self-Trauma
To stop your dog from licking and chewing the healing area, use an Elizabethan collar (cone) or soft recovery collar. Some dogs tolerate inflatable donut collars better than traditional cones.
Home Care Steps
If veterinary care isn’t immediately available, carefully trim hair around the hot spot using blunt-ended scissors to remove excess fur.
Gently clean the area with mild, pet-safe antiseptic, never use hydrogen peroxide or alcohol, which damages tissue. Keep the area dry. Apply veterinary-approved hot spot sprays like Vetericyn.
Hot Spot Healing Stages

Pictures of hot spots on dogs at various healing stages show different characteristics:
Stage One (24-72 hours): Bright red or yellow begins turning pink or pale pink.
Stage Two (3-5 days): Swelling reduces, the lesion feels cooler to touch. Color continues fading to light pink.
Stage Three (5-7 days): Wound edges begin closing, lesion size decreases significantly.
Stage Four (7-10 days): Fresh pink, healthy tissue develops across the wound.
Stage Five (10-14 days): Hair growth begins, skin returns to normal appearance.
Most hot spots heal within 7-10 days with proper treatment; severe cases may take 2-3 weeks.
Prevention Strategies
Preventing hot spots is better than treating them:
Regular Grooming
Consistent brushing prevents matting. Seasonal grooming helps thick-coated breeds stay cool and dry. Trim long hair during summer months to improve air circulation.
Keep Completely Dry
Always ensure your dog is thoroughly dried after baths, swimming, or rain. Use towels and blow dryers for thick coats. Pay special attention to skin folds and dense fur areas.
Parasite Control
Maintain year-round flea and tick prevention. Regular treatments prevent parasite-induced itching that leads to hot spots.
Address Allergies
Work with your veterinarian to identify and manage allergies through appropriate diets, medications, or environmental changes.
Provide Mental Stimulation
Reduce anxiety-driven licking through adequate exercise, interactive toys, and mental enrichment activities.
Conclusion
Understanding what pictures of hot spots on dogs reveal enables you to identify these painful skin lesions early and seek appropriate treatment. When addressed promptly, acute moist dermatitis typically heals within 7-10 days.
You can keep your dog comfortable and healthy by recognizing visual symptoms, addressing underlying causes, and implementing preventive measures. At the first sign of a hot spot, consult your veterinarian to ensure proper diagnosis and treatment, preventing complications and recurrence.
Frequently Asked Questions
Can hot spots heal on their own?
While mild cases might resolve without treatment, this is unlikely because dogs continue licking and scratching the affected area.
Untreated hot spots typically increase in size and develop secondary bacterial infections. Veterinary treatment accelerates recovery and prevents complications.
Are hot spots contagious to other pets or humans?
Bacterial hot spots aren’t contagious to other dogs or humans. However, if the underlying cause involves parasites like fleas or mites, these parasites can transfer to other pets and may bite humans. Treating the root cause protects everyone in the household.
How can I distinguish between hot spots and ringworm?
Pictures of hot spots on dogs show moist, oozing lesions, while ringworm appears as dry, scaly circular patches with hair loss.
Hot spots are very painful and intensely itchy, while ringworm causes milder itching. Ringworm is a fungal infection requiring different treatment than bacterial hot spots.
