Why is my dog getting repeated hot spots?

Overview
Repeated hot spots usually mean something is making your dog itch, lick or chew the same area over and over. The spot itself is often the result, not the original problem, so there may be several possible causes rather than one simple answer.
Common triggers include allergies, fleas, moisture in the coat, matting, skin irritation, ear problems, or pain that makes your dog keep bothering one area. If the spots keep coming back, it’s worth looking for the pattern and checking for anything that could be setting off the cycle.
Things To Check
1. Check whether the spots appear after swimming, bathing, wet weather, muddy walks or a full groom.
2. Look for fleas, flea dirt, ticks or signs that your dog is scratching more than usual.
3. Examine the coat for mats, tangles or areas where moisture may be trapped against the skin.
4. Note whether the hot spots are always in the same place, which can point to a repeated irritant or a sore area your dog keeps licking.
5. Check for redness, swelling, broken skin, scabs, discharge or a bad smell.
6. Look at the ears, paws and belly as well, since itchiness in one area can lead to licking or chewing somewhere else.
7. Think about any recent changes in food, bedding, grooming products, washing routine or home environment.
Common Causes
Allergies are one of the most common reasons hot spots keep coming back. Dogs may react to things in the environment, food, fleas or contact irritants, and the skin can flare up when they scratch or lick.
Fleas and other biting insects can also trigger repeated irritation, even if you only spot them occasionally. Some dogs react strongly to just a few bites.
Moisture, matting and poor skin drying can make the skin more vulnerable, especially in thick-coated dogs. Once an area becomes sore, licking and chewing can quickly make it worse.
Less commonly, an underlying ear problem, a painful joint, anal gland discomfort or another source of irritation can lead to repeated licking in the same place.
What To Do
Try to spot the pattern first. Write down when each hot spot appears, where it is, what your dog had been doing beforehand and whether there were any changes in the coat, skin or environment.
Keep the area as clean and dry as you can, and prevent your dog from licking or scratching it more. Gentle grooming to remove mats can also help reduce trapped moisture and irritation.
Stick to a steady flea-control routine if fleas are part of the problem, and review whether anything at home or on walks might be irritating your dog’s skin. If your dog has recurring flare-ups, a vet can help work out whether allergy, infection or another cause is behind the pattern.
When To Contact A Vet
Book a vet check if the hot spots keep returning, are spreading, seem very painful, smell strongly, or are not improving with sensible home care. Your vet may need to look for an underlying cause such as allergy, infection, parasites or another skin problem.
Products That May Help
If your dog is prone to sore or itchy skin, routine washing and grooming can help you keep an eye on changes and stay on top of everyday hygiene.
