Hot Spots on Dogs: How to Treat Them and Stop the Licking

Last updated: June 2026

A hot spot can go from a small red patch to a raw, oozing sore in a matter of hours, because the more a dog licks and chews it, the worse it gets. Breaking that cycle quickly is the whole game. Here's what hot spots are, how to treat them, and how to stop the licking that fuels them.

What is a hot spot on a dog?

A hot spot is a localized area of inflamed, infected skin — medically called acute moist dermatitis — that develops when a dog repeatedly licks, chews, or scratches one spot. It appears as a red, moist, often hairless patch that can spread rapidly, sometimes doubling in size within a day. Hot spots are most common in warm, humid weather and in thick-coated breeds.

What causes hot spots on dogs?

Hot spots are caused by anything that triggers a dog to lick or scratch one area repeatedly, which then becomes infected. The most common triggers are flea bites, allergies, trapped moisture, ear infections, anal gland problems, and boredom or stress. The licking itself is what turns a minor itch into an open sore.

How do you treat a hot spot on a dog?

To treat a hot spot, clip the hair around it, clean it gently with a vet-safe antiseptic, keep it dry, and stop the dog from licking it. Many cases need a vet visit for antibiotics, anti-inflammatories, or medicated treatment. The single most important step is preventing further licking, because the wound cannot heal while the dog keeps reopening it.

Step 1 — Clip the area. Carefully trim the fur around the hot spot so air can reach the skin and you can see the full extent.

Step 2 — Clean it. Use a vet-recommended antiseptic or a saline solution. Pat dry; moisture feeds the infection.

Step 3 — Stop the licking. Put a recovery collar on. This is non-negotiable — without it, treatment fails.

Step 4 — See your vet. Spreading, painful, or oozing hot spots usually need prescription treatment. Don't wait, since they grow fast.

How do you stop a dog from licking a hot spot?

The reliable way to stop a dog licking a hot spot is a recovery collar that physically blocks access while the skin heals. A soft inflatable collar works well for hot spots on the body, legs, and rear, since it keeps the dog from bending back to the area without blocking vision or eating. Pair it with vet treatment for the fastest recovery.

How to prevent hot spots from coming back

Prevent hot spots by addressing the underlying cause: keep up consistent flea prevention, manage allergies with your vet, dry your dog thoroughly after swimming or baths, groom thick coats to prevent matting, and treat ear infections promptly. A dog that isn't itchy doesn't start the lick-scratch cycle that creates hot spots.

Frequently Asked Questions

Can a hot spot heal on its own?

Rarely, and not while the dog keeps licking it. Small hot spots may improve if you stop the licking immediately and keep the area clean and dry, but most need veterinary treatment to clear the infection and prevent spreading.

How long does a dog hot spot take to heal?

With proper treatment and a recovery collar to stop licking, most hot spots improve within 3 to 7 days and heal in 1 to 2 weeks. Healing stalls if the dog continues to lick the area, which is why the collar matters.

Should I cover my dog's hot spot?

Hot spots generally heal best with air exposure, kept clean and dry, rather than covered with a tight bandage. Use a recovery collar to block licking instead of wrapping the area, unless your vet specifically advises a dressing.

What can I put on a dog's hot spot at home?

You can clean it with a vet-safe antiseptic or saline and keep it dry, but avoid human creams unless your vet approves them. Many hot spots need prescription medication, so home care is a first step, not a substitute for veterinary advice.

Do hot spots hurt dogs?

Yes. Hot spots are painful and intensely itchy, which is why dogs lick and chew them so persistently. Treating the discomfort and blocking access with a collar both help break the cycle.
