Pemphigus Foliaceus in Dogs
Pemphigus Foliaceus is a medium-severity autoimmune condition that can affect dogs of all ages and breeds. Pemphigus foliaceus is the most common autoimmune skin disease in dogs, characterised by immune-mediated destruction of intercellular connections in the superficial epidermis, resulting in pustule and crust formation particularly on the face and paws. It is documented across 5 breeds, though prevalence and severity can differ significantly between them. It typically becomes apparent at 4-8 years. Early signs to watch for include pustules and crusts on muzzle, ears, and footpads, footpad scaling and crusting, generalised spread in severe cases, and secondary infection. When treatment is required, costs are estimated at £600-£2,500/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.
