Demodectic Mange

descriptionOverview

Demodectic mange is caused by Demodex mites that live naturally in hair follicles. When a dog's immune system is weakened — from stress, illness, poor nutrition, or genetics — mites multiply unchecked, causing hair loss and skin lesions. It's not contagious to humans or other adult dogs. Puppies often get it from their mother and most outgrow it as their immune system matures.

searchSymptoms to Watch For

• warningPatchy hair loss, usually starting on the face
• warningRed, scaly skin lesions
• warningNo itching in early stages (unlike sarcoptic mange)
• warningSecondary bacterial infections in severe cases
• warningGeneralized hair loss and thickened skin if untreated

restaurantHow Nutrition Helps

A strong immune system is the primary defense against Demodex overgrowth. High-quality protein supports immune cell production. Zinc, vitamin E, and omega-3 fatty acids support immune function and skin health. Malnourished dogs are much more susceptible. Ensuring complete, balanced nutrition is both preventive and supportive during treatment.
