What Is Lip Fold Dermatitis In Dogs?
Lip fold dermatitis (lip fold pyoderma) is a form of skin fold dermatitis (Intertrigo) in dogs, whose conformation allows for infection-prone folds in the skin. These are most common in breeds with unusual conformations pronounced in facial, vulvar, and tail folds; however, they can arise in any deep skin fold anywhere in the dog’s body.
Derma in Greek means “skin” and “-itis” means inflammatory condition. When the folds created by the dog's sagging lips trap moisture and debris (such as food particles) continuously, they will be unusually moist and may appear irritated and inflamed. The fold may be stinky and smell awful. Severe lip fold dermatitis in dogs breaks the skin, ulcers may form and infection can occur. Bacterial and Yeast infections are more common in dog skin folds.
Skinfold dermatitis is a dermatologic condition that leads to a skin infection, called pyoderma. Historically, both skin fold dermatitis and skin fold pyoderma are classified as a type of superficial pyoderma. Currently, they are categorized as a type of ‘surface pyoderma’ together with pyotraumatic dermatitis (“hot spots”).
Skinfold Dermatitis can occur in other parts of a dog’s body including the face, neck, vulva, and tail folds. Some breeds that have larger, saggier, floppier lips are more prone to lip fold dermatitis.

Additional Facts For Lip Fold Dermatitis In Dogs
Infection: The most common organisms found in cytology specimens of lip fold dermatitis suggest a mixed population of organisms.
Coccoid bacteria, bacilli, and yeast, including Streptococcus, Staphylococcus, Malassezia, and Pseudomonas species.
Other potential underlying causes are allergic skin diseases, skin-on-skin friction (intertrigo), and hormonal influences.
The pathogenesis of lip fold dermatitis irritation and decreased air circulation and irritation, resulting in a damp, warm environment promotes localized microbiome proliferation.
These microbes in turn produce toxins and cause maceration of the skin making it itchy, red, and painful. Microbial penetration is enhanced into deeper skin compartments (epidermal/dermal) and causes ongoing inflammation and infection.
There is no documented mortality due to this condition.
- Cytology tests
- Patch tests
- Culture tests
The prognosis for lip fold dermatitis is really good. As the existing condition is not life-threatening, no rigorous treatment is usually necessary. However, relapse is possible following medical treatment in affected dogs. Proper hygiene and home care are the best defenses against future recurrences.
