Quick answer: To treat a hot spot on your dog, trim the fur around the sore, clean it with a mild antiseptic, keep it dry, apply a vet-approved topical (often a hydrocortisone or antibiotic), and stop your dog from licking or biting it with an e-collar or recovery suit. Most mild hot spots calm down within a few days; if it spreads or oozes, see your vet. I'm Preston Smith, co-founder of Bully Sticks Central, and below is the plain, step-by-step version we share with dog owners.
What Is a Hot Spot on a Dog?
A hot spot — the clinical name is acute moist dermatitis — is a patch of inflamed, infected skin that looks red, moist, and raw. It's intensely itchy, so it tends to start small and grow fast because the dog won't leave it alone. According to VCA Animal Hospitals, the licking and chewing that follows the initial itch is what turns a minor irritation into an open, weeping sore.
What Causes Hot Spots?
Anything that makes a dog scratch or lick one spot repeatedly can start a hot spot. Common triggers include: allergies (food or environmental), flea and insect bites, trapped moisture from swimming or bathing, poor grooming or matted fur, and underlying skin infections. The American Kennel Club notes that thick-coated breeds and dogs with allergies are especially prone.
How Do You Treat a Hot Spot on a Dog, Step by Step?
- Trim the fur around it. Carefully clip the hair surrounding the sore so air can reach it and it can stay dry. Damp, covered skin keeps a hot spot alive.
- Clean the area. Gently wash it with a mild, dog-safe antiseptic solution to remove debris and cut down on bacteria.
- Apply a vet-approved topical. Depending on severity, a vet may recommend a hydrocortisone spray to calm the itch and inflammation, plus an antibiotic if it's infected. Don't reach for random human creams without checking first.
- Stop the licking. This is the step people skip and then wonder why it won't heal. An Elizabethan collar (e-collar) or a recovery suit protects the spot so it can actually close up.
- Watch it for a few days. A mild hot spot should start improving quickly. If it grows, oozes, smells, or your dog seems painful or feverish, get to the vet.
- Prevent the next one. Regular grooming, flea control, drying your dog thoroughly after swims, and good nutrition (including omega fatty acids for skin and coat) all lower the odds of a repeat.
Keeping Your Dog Distracted While It Heals
The hardest part of treating a hot spot is boredom — a bored dog goes right back to licking. A long-lasting chew keeps the mouth busy and the mind occupied so the sore gets left alone. We built Bully Sticks Central around single-ingredient chews for exactly this reason: our bully sticks are 100% natural, 100% real meat, fully digestible, contain no rawhide, and are ethically sourced from grass-fed American and Argentinean farms. Because they're single-ingredient, there are no fillers or additives that could aggravate a dog already dealing with allergy-related skin flare-ups. If you want a lighter option, a beef trachea chew is another 100% natural, single-ingredient way to keep a recovering dog occupied.
When Should a Hot Spot Go to the Vet?
Call your vet if the hot spot is larger than a coin, keeps spreading, weeps pus, gives off an odor, or your dog is in obvious pain, lethargic, or running a fever. Recurring hot spots also deserve a workup — they're usually a symptom of an allergy or other underlying condition that home care alone won't fix.
The Bottom Line
Hot spots look alarming but most respond well to simple care: clean it, dry it, treat it, and stop the licking. Address whatever caused it, keep your dog comfortable and distracted while it heals, and loop in your vet if it isn't improving. Every chew we make is 100% high-quality guaranteed, so a recovering dog gets something safe to focus on instead of the itch.
