Hot spots (acute moist dermatitis) are red, moist, painful patches of skin that can appear and spread within hours. They're often triggered by allergies, fleas, ear infections or a pet licking and scratching one area.
Treatment usually includes clipping and cleaning the area, medication to ease pain and itch and to treat infection, and finding the underlying cause so hot spots don't keep coming back.
Signs Your Dog Has a Hot Spot
Hot spots can appear seemingly overnight and grow quickly, especially in thick-coated breeds and during warm, humid weather. They are often much larger and more painful than they look, because matted fur can hide the true size of the sore. Dogs that swim often or have allergies tend to get them more. It's best to have them checked promptly. Look for:
- A red, raw or oozing patch of skin
- Matted, wet or crusty fur over the area
- Hair loss in a well-defined spot
- Constant licking, chewing or scratching at one area
- An unpleasant odor
- Pain, flinching or growling when the area is touched
Caring for Your Dog at Home After Hot Spot Treatment
The goal at home is to keep the area clean, dry and protected while it heals. Follow your vet's instructions on cleaning the spot and giving any prescribed medications for the full course, even if it starts to look better. An e-collar or protective shirt can stop licking and chewing that slow healing.
Avoid bathing or swimming unless your vet says it's okay, and don't apply human creams or home remedies without checking first. Keep your dog on year-round flea prevention, keep up with regular grooming and dry your dog thoroughly after baths or swims. Call us if the area spreads, oozes more or your dog seems uncomfortable.
