Bullous Pemphigoid is an autoimmune disease, affecting dogs, cats, horses and pigs. It is very rare. The disease causes subepidermal vesicular dermatitis. The target autoantigen is a protein located in the basement membrane, hence immune attack leads to separation of the epidermis and dermis. | Bullous Pemphigoid is an autoimmune disease, affecting dogs, cats, horses and pigs.
