How to Treat Dog Hot Spots at Home

What Are Dog Hot Spots?

Hot spots (acute moist dermatitis) are red, moist, painful skin lesions that develop rapidly when a dog licks, chews, or scratches one area repeatedly. They can appear suddenly and double in size within hours. Hot spots are most common in dogs with thick coats, in warm humid weather, and in dogs with underlying allergies or skin conditions.

Signs of a Hot Spot

• Red, moist, raw-looking patch of skin
• Matted fur around the area
• Oozing or crusting discharge
• Foul smell
• Dog constantly licking, chewing, or scratching the area
• Pain when the area is touched
• Hair loss around the lesion

Step-by-Step: How to Treat a Dog Hot Spot at Home

Step 1: Clip the Hair Around the Hot Spot

Carefully clip the fur around and slightly beyond the hot spot using blunt-tipped scissors or a clipper. This exposes the lesion to air, which is essential for healing. Moisture trapped under fur is what allows hot spots to grow. Be gentle — the skin is very sensitive.

Step 2: Clean the Area

Gently clean the hot spot with a mild antiseptic solution or saline. Pat dry with a clean cloth — do not rub. Removing discharge and bacteria is critical to stopping the infection from spreading.

Step 3: Apply a Hot Spot Treatment Spray

Apply a veterinarian-recommended hot spot spray to soothe the skin, reduce inflammation, and fight bacteria. Allow to air dry completely.

💊 Recommended: Hot Spot Spray — Holistic Natural Herbal Formula — Fast-acting, soothes hot spots and relieves irritated skin and rash. Veterinarian recommended, made in USA, 8 oz.

Step 4: Prevent Licking

This is the most critical step. If your dog continues to lick the hot spot, it will not heal. Use an Elizabethan collar (cone) or a soft recovery collar to prevent access to the area. Keep it on until the hot spot is fully healed — usually 7–14 days.

Step 5: Address the Underlying Cause

Hot spots don't appear randomly — they're triggered by something causing your dog to scratch or lick. Common triggers include:

• Allergies (most common) — see our guide on how to treat dog allergies at home
• Flea bites — see our guide on how to treat dog flea infestation at home
• Ear infection causing head shaking and scratching
• Boredom or anxiety (behavioral licking)
• Moisture trapped in the coat (after swimming or bathing)
• Matted fur

Step 6: Monitor Daily

Check the hot spot daily. It should start drying out and shrinking within 2–3 days. If it's spreading, getting deeper, or showing signs of severe infection (pus, strong odor, swelling), see a vet.

Soothe Surrounding Skin

💊 Recommended: PAWFUME Skin & Coat Soothing Spray — Apply to the skin around (not on) the hot spot to soothe irritation and reduce itching in surrounding areas.

How to Prevent Hot Spots

• Keep your dog's coat clean, dry, and well-groomed
• Dry your dog thoroughly after swimming or bathing
• Treat allergies proactively
• Maintain strict flea prevention
• Provide mental stimulation to reduce boredom licking
• Brush regularly to prevent matting

When to See a Vet

• Hot spot is larger than a quarter when you first notice it
• Spreading rapidly despite treatment
• Deep, oozing, or foul-smelling
• Your dog is in significant pain
• Not improving after 3–4 days of home care
• Recurring hot spots (indicates an underlying condition needing diagnosis)

Vets typically treat hot spots with prescription antibiotics, steroids, or medicated sprays for faster resolution.
