Malassezia Dermatitis in Dogs
Malassezia Dermatitis is a medium-severity dermatological condition that can affect dogs of all ages and breeds. Malassezia pachydermatis is a lipophilic yeast that normally inhabits dog skin and ear canals. Overgrowth caused by allergies, hormonal disease, or skin fold moisture leads to intensely pruritic, greasy, malodorous skin dermatitis typically in skin folds and ears. It is documented across 5 breeds, though prevalence and severity can differ significantly between them. It typically becomes apparent at 1-4 years. Early signs to watch for include intense itching, greasy yellowish-brown skin discharge, musty or rancid odour, and redness in skin folds and between toes. When treatment is required, costs are estimated at £300-£1,500/year depending on severity, location, and the specific intervention needed. This page covers symptoms, treatment options, and preventive steps — along with breed-specific information where available.
