Hot spots can appear quickly and become painful fast. This guide explains what pet parents can do first, what usually needs veterinary help, and how to reduce licking while the skin heals.

Hot spots are irritated skin patches that may look red, moist, raw, or crusted. Dogs often lick, scratch, chew, or rub the area because it feels itchy or painful.
Prevent licking first because repeated licking can make the sore larger. Use an e-collar or recovery collar if your dog keeps reaching the area. Keep the skin dry and avoid covering it tightly unless your vet gives bandage instructions.
Veterinary care may include clipping fur around the lesion, cleaning the skin, treating infection, controlling itch or pain, and looking for the trigger. Common triggers include allergies, fleas, ear problems, wet fur, and repeated friction.
Most hot spot problems get worse when owners try too many products at once or wait while the lesion spreads.
Before calling your vet, gather details that help triage the issue.
Call your veterinarian promptly if the hot spot is painful, spreading, wet, bleeding, smelly, near the ear or face, or paired with low energy. Same-day care is safest for large or rapidly worsening lesions.

Avoid peroxide, alcohol, essential oils, human antibiotic creams, and steroid creams unless your vet specifically approves them. These can irritate skin or be unsafe if licked.
Hot spots can itch, burn, or hurt. Licking temporarily soothes the feeling but usually worsens inflammation and infection risk.
Healing time depends on size, infection, and the trigger. With proper treatment, many improve within days, but the skin and hair coat may take longer to fully recover.
