Overview
Call the vet if the hot spot is spreading, very painful, oozing, smelly, or not improving after a day or two of sensible home care. Mild spots can sometimes be managed at home at first, but there are several possible causes, and some dogs need treatment to stop the irritation from getting worse.
Things To Check
1. Check how quickly it appeared and whether it seems to be getting bigger over a few hours or days.
2. Look closely for redness, moisture, discharge, scabs, broken skin, swelling, or an obvious bad smell.
3. See whether your dog is licking, biting, rubbing, or scratching the area repeatedly.
4. Check if the spot is near the ear, neck, base of the tail, armpit, groin, or another area that traps moisture or friction.
5. Think about recent triggers such as bathing, swimming, muddy walks, grooming, clipping, insect bites, or a change in shampoo or bedding.
6. Check for signs your dog feels unwell, such as reduced energy, being off their food, or seeming more uncomfortable than usual.
7. Make sure there are no nearby mats, knots, collars, harness rubbing, or trapped debris that could be irritating the skin.
Common Causes
Hot spots are often linked to self-trauma, where licking or scratching makes a small irritation much worse. Common triggers include damp coat, matted fur, insect bites, allergies, grooming irritation, friction from collars or harnesses, and minor skin infections.
Sometimes the original trigger is hard to spot. In some dogs, an ear problem, sore skin under the fur, or another itch source can lead to the area being over-licked and then inflamed.
What To Do
Gently stop your dog from licking or scratching the area so it has a chance to settle. Keep the skin as clean and dry as you can, and avoid bathing, creams, or home remedies unless your vet has already advised them.
If the fur around the area is long or matted, avoid cutting too close to the skin yourself unless you’re confident doing so safely. Keep an eye on the spot over the next 24 to 48 hours and note whether it is improving, staying the same, or worsening.
If the skin looks more irritated, the area seems painful, or the hot spot keeps coming back, it’s sensible to speak to your vet. They can check whether there’s an underlying cause that needs treatment.
When To Contact A Vet
Call your vet sooner if the hot spot is spreading quickly, your dog seems very sore, the skin is oozing or smells unpleasant, or the area is swollen. You should also contact them if your dog seems unwell, the spot is near the eye or ear, or it isn’t improving after a short period of sensible home care.
Vet advice is also a good idea if hot spots are becoming a repeated problem, because there may be an ongoing trigger such as allergies, parasites, or another skin issue that needs checking.
Products That May Help
If your dog is prone to skin irritation, a good washing and grooming routine can be useful as part of day-to-day care and keeping an eye on their coat and skin.
