Overview
A red, wet patch of skin in summer is often a hot spot, which is a sore area that can become irritated quite quickly. It can look alarming, but there are several possible causes, including licking, scratching, insect bites, allergies or moisture trapped in the coat.
Things To Check
1. Check whether your dog has been licking, chewing or scratching the area more than usual.
2. Look closely for redness, broken skin, discharge, swelling, scabs or an unpleasant smell.
3. Note where the patch is, as hot spots are often seen on the rump, chest, neck or near the ears.
4. Think about whether it started after swimming, bathing, wet weather or a grooming session.
5. Check for anything that might be triggering itchiness, such as fleas, flies, grass seeds or a new shampoo.
6. See if your dog seems uncomfortable when the area is touched.
7. Notice whether the patch is spreading or becoming more moist over a short time.
Common Causes
The most common reason is a hot spot, which often starts with itchiness and then gets worse because the dog keeps licking or scratching it. Summer moisture, heat and thick coats can make this easier to develop.
Other common causes include flea irritation, insect bites, minor skin allergies, or skin that stayed damp after swimming, washing or wet grass.
Less commonly, a skin infection or another underlying problem may be contributing, especially if the area keeps coming back or does not improve.
What To Do
Gently stop your dog from licking or scratching the area, because continued irritation can make it worse. If the coat around the patch is long or matted, careful trimming by a professional groomer or vet may help the skin dry out more easily.
Keep the area clean and dry, and avoid using human creams, powders or scented products unless your vet has advised them. If the patch came after swimming or exercise, dry your dog thoroughly afterwards and keep an eye on whether the redness is settling or spreading.
If your dog seems very itchy, the patch is getting larger, or the skin looks sore or smelly, it is sensible to speak to your vet.
