A hot spot is a rapidly developing patch of inflamed, moist and painful skin created when a dog repeatedly scratches, licks or chews one area. It is a visible consequence of an underlying trigger rather than a diagnosis that explains why the irritation began.

Home care

Prevent licking with the recommended collar or garment and keep the area clean and dry as directed. Do not apply alcohol, peroxide, essential oils, human creams or leftover medicines, which may sting, delay healing or be unsafe if swallowed.

Prognosis

Uncomplicated superficial lesions often improve quickly once they are cleaned and protected. Recurrence is likely if the allergy, parasite, moisture or pain that started the episode remains unresolved.

Summary

A hot spot needs both immediate comfort care and investigation of its trigger. Breaking the lick-scratch cycle can heal the skin; preventing the next episode depends on solving the reason it started.

Overview

A hot spot is a rapidly developing patch of inflamed, moist and painful skin created when a dog repeatedly scratches, licks or chews one area. It is a visible consequence of an underlying trigger rather than a diagnosis that explains why the irritation began.

Symptoms

The area is typically red, wet, hairless and sharply uncomfortable, with matted surrounding hair and sometimes an unpleasant smell. A dog may be restless, guard the area or return to licking as soon as attention is diverted.

Causes

Fleas, allergy, an ear problem, a wet or matted coat, insect bites and local pain can start the itch-chew cycle. Moisture and surface bacteria then contribute to inflammation, while continued self-trauma can enlarge the lesion within hours.

Risk Factors

Dogs with dense coats, frequent swimming, poor coat drying or allergic skin disease are more susceptible, particularly in warm humid weather. Any dog can develop a hot spot if irritation is intense enough.

Diagnosis

A veterinarian examines the full skin and ears, clips hair when appropriate and may use skin cytology, parasite tests or other investigation to identify infection and the initiating problem. Deeper infection or another lesion can resemble a simple hot spot.

Treatment Options

Treatment usually involves carefully exposing and cleaning the area, stopping self-trauma, providing pain and itch control and addressing the trigger. Antimicrobial treatment is chosen according to the depth and extent of infection rather than used automatically.

Recovery

Uncomplicated superficial lesions often improve quickly once they are cleaned and protected. Recurrence is likely if the allergy, parasite, moisture or pain that started the episode remains unresolved.

Prevention

Maintain flea control, manage known allergies, dry dense coats thoroughly and deal promptly with ear disease or matting. Regular grooming makes a small irritated patch easier to find before repeated licking expands it.

When to Contact a Vet

Prompt care is appropriate because hot spots can be very painful and spread quickly. Same-day assessment is advisable for extensive, foul-smelling or deeply swollen lesions, fever, marked lethargy or a dog that cannot be comfortably examined.

Frequently Asked Questions

Can I clip a hot spot at home?

Clipping painful inflamed skin can cause injury and some dogs need sedation, so veterinary handling is often safer.

Are hot spots contagious?

The lesion itself is generally not contagious, but an underlying parasite or fungal condition could affect other animals and should be ruled out.

Can my dog swim while a hot spot heals?

Usually the area should remain dry until the veterinarian confirms healing. Swimming can add moisture and contamination and may delay recovery.
