Overview
Yes, your dog’s wrinkles can cause a skin infection. Skin folds can trap moisture, heat, dirt and rubbing, which may lead to sore, inflamed skin if they’re not kept clean and dry. It’s often manageable, but there can be more than one reason a fold becomes irritated, so it’s worth checking it properly.
Things To Check
1. Check whether the problem is worse after exercise, grooming, wet weather or eating and drinking.
2. Look closely for redness, dampness, a bad smell, broken skin, discharge, scabs or swelling in the folds.
3. Gently feel the area for heat or tenderness, and notice if your dog pulls away when you touch it.
4. Check if the folds are getting trapped with saliva, food, tears or mud.
5. See whether your dog is licking, rubbing or scratching the area more than usual.
6. Note if the skin looks greasy, flaky or very moist, as this can help suggest what kind of irritation is happening.
7. Keep an eye on whether the issue is limited to one fold or affecting several areas.
Common Causes
The most common cause is skin fold dermatitis, where moisture and friction build up inside the wrinkle and irritate the skin. Bacteria and yeast may then overgrow in that warm, damp environment.
Other common contributors include poor drying after washing or getting wet, trapped debris, and repeated rubbing from the shape of the fold.
Less commonly, allergies, licking linked to discomfort elsewhere, or another skin problem may be making the folds worse.
What To Do
Keep the folds as clean and dry as you can. After walks, feeding, drinking or bathing, check the area and gently dry any moisture that’s collected.
Avoid harsh scrubbing, scented products or over-washing, as these can irritate the skin further. Regular monitoring helps you spot changes early, especially if your dog has deep wrinkles or has had this problem before.
If the area is only mildly damp, simple cleaning and careful drying may help settle it. If it keeps coming back, try to note when it flares up and what seems to trigger it.
When To Contact A Vet
Contact your vet if the skin is painful, very red, smelly, swollen or oozing, or if your dog seems bothered by it despite careful home care. Ongoing or recurring fold problems may need proper treatment to stop them getting worse.
Products That May Help
For dogs with skin folds, gentle routine grooming and washing can be useful as part of everyday care, especially when you’re trying to keep the area clean and comfortable.
