Overview
If your dog’s skin folds are infected, you’ll often notice redness, a bad smell, dampness, soreness or discharge. Some dogs also lick, scratch or seem uncomfortable when the area is touched. There can be several causes, including trapped moisture, friction and irritation, so it’s worth checking the area carefully rather than guessing.
Things To Check
1. Look for redness, swelling, broken skin, scabs or any wet-looking patches within the fold.
2. Notice whether there’s an unusual smell, as a strong musty or sour odour can be a common sign of skin trouble.
3. Check for discharge, crusting or sticky material, especially where the skin folds sit tightly together.
4. Feel gently for warmth or tenderness, because sore skin may make your dog pull away or react when touched.
5. Watch for licking, scratching, rubbing or restlessness, which can suggest the area is bothering them.
6. See whether the skin looks greasy, damp or stuck together, since trapped moisture often makes fold problems worse.
7. Think about when it started, such as after exercise, warm weather, swimming or a grooming session.
Common Causes
The most common cause is moisture being trapped in the fold, which can lead to irritation and sometimes infection. Friction between skin surfaces can also make the area sore.
Skin fold dermatitis can sometimes be linked to allergies, over-licking, excess skin oils or yeast and bacterial overgrowth. Less commonly, foreign material or another skin condition may be involved.
What To Do
Keep the folds as clean and dry as you can using a gentle, routine approach. After walks, bathing or exercise, check the area and dry it carefully if it has become damp.
Avoid using scented products, harsh wipes or anything that stings, as this can make the skin more irritated. If the area is getting repeatedly sore, keep a brief note of when it flares up and what seems to trigger it.
If your dog tolerates it, you can make fold checks part of your normal grooming routine so you spot changes early. It also helps to keep bedding and resting areas clean and dry.
When To Contact A Vet
Speak to your vet if the skin is very sore, there is discharge, swelling or a strong smell, or if the problem keeps coming back. Ongoing fold irritation can need proper assessment, especially if your dog seems unwell or the skin is starting to break down.
Products That May Help
Keeping skin folds clean and dry is often easier when you have routine grooming and hygiene items on hand. The right basics can support day-to-day care without overcomplicating things.
