Skin Fold Dermatitis in Dogs: Wrinkle Infections and Care

By Tailwisp Editorial TeamUpdated October 17, 20263 min read

Wrinkles are an adorable breed trait, but the creases need regular care to stay healthy.

What it is

Skin fold dermatitis, or intertrigo, is inflammation and infection in places where skin rubs against skin. Moisture from tears, saliva, sweat or urine and limited airflow encourage bacteria and yeast to multiply.

Where it happens

• Facial wrinkles and nose folds
• Lip folds, causing a smell near the mouth
• Tail pocket in screw-tailed breeds
• Vulvar folds, which can lead to urine scalding
• Neck and body folds
• Between toes in some dogs

Breeds at higher risk

English and French bulldogs, pugs, shar-peis, bullmastiffs, boxers, cocker spaniels and basset hounds, plus overweight dogs of any breed. See health issues in flat-faced breeds.

Signs

• Redness and moist skin
• Bad smell
• Brown or greasy discharge
• Hair loss in the fold
• Scratching, rubbing or scooting. See dog scooting causes
• Pain when touched
• Sores or crusts

Why infection follows

Warm, moist folds support yeast and bacterial overgrowth. See yeast infections in dogs and pyoderma in dogs. Allergies and weight can make folds worse. See dog skin allergies.

Daily and weekly care

1. Check every fold daily or at least a few times a week.
2. Wipe gently with a damp cloth or vet-recommended wipes.
3. Dry thoroughly, since moisture is the main enemy.
4. Use a vet-approved medicated wipe or cleanser as advised.
5. Keep hair trimmed around folds.
6. Wipe tear stains and food residue from the face.
7. Avoid heavy powders and creams unless your vet advises.

Treatment

Your vet may take samples to identify bacteria or yeast, then prescribe medicated cleansers, topical or oral medication and treat any underlying cause. See dog antibiotics guide.

Weight management

Extra weight deepens folds and traps moisture. See dog obesity risks.

Surgery

For severe, recurrent cases, procedures such as fold removal or tail pocket surgery may be considered. Discuss benefits and recovery with your vet. See dog stitches and incision care.

Prevention at home

Dry after baths and swims, keep sleeping areas clean, wash bedding and use a gentle grooming routine. See how to brush a dog properly.

Choosing a dog

Consider breeds and lines with shallower folds and healthy proportions.

Questions to ask your vet

Ask which folds need daily care, which products to use and whether surgery may help.

Common mistakes

• Cleaning too rarely
• Leaving folds damp
• Using harsh alcohol wipes
• Skipping vet visits for persistent smell

Troubleshooting

• My bulldog smells like corn chips: check for yeast and book a vet visit.
• The tail pocket is raw: keep it clean and dry, and see your vet.
• Wipes seem to irritate: ask for a gentler product.

A simple plan

1. Check folds daily.
2. Clean and dry.
3. Control weight.
4. See a vet for persistent signs.

Real-life examples

A bulldog's face folds stay healthy with a daily wipe. A pug's owner switches to a vet-recommended cleanser and the smell fades. A shar-pei needs surgery to resolve chronic infections. Routine helps.

Daily habit

A minute of care prevents weeks of discomfort.

Bathing and drying routine

Use a gentle, vet-approved shampoo and rinse thoroughly, since residue can irritate. Pat folds dry with a clean towel, then use a cool setting on a hair dryer held at a distance if your dog tolerates it. Moisture left behind undoes the benefit of cleaning.

Tear stains and drool

Wipe tear stains and drool daily with a damp cloth, because constant wetness feeds infection. If tears overflow heavily, ask your vet whether a blocked duct or eye problem needs treatment.

The takeaway

Clean and dry skin folds regularly, and see a vet for persistent redness, smell or pain.
