Many diseases affect the skin on the noses of dogs. This includes bacterial or fungal infections of the skin, or mites. These diseases may affect the bridge of the nose where there is hair, or the smooth part of the nose, where there is no hair. Often, it is the portion of the nose that has hair that is affected. In the case of systemic diseases like lupus or other autoimmune ailments, the whole muzzle is involved.
