discoid_lupus

Discoid lupus is an immune mediated skin disease that is probably related to systemic lupus erythematosus (SLE) but instead of affecting the whole body as SLE does, it primarily affects the nose and face. As far as I know, there is no known cause of this problem but it does seem more frequent in dogs of the German Shepherd, Collie, Brittany spaniel. Shetland Sheepdog, Siberian Husky and German Shorthaired Pointer breeds.

The disease normally starts as loss of pigment around the nose. There may be scabby sores or just scaling of the nasal tissue.

early_juvenile_cellulitis

In a very young puppy with noticeably swollen lymph nodes the first problem that comes to mind is "puppy strangles" or juvenile cellulitis. This is also sometimes referred to as juvenile pyoderma. This is a disorder affecting puppies that causes swelling, pustules, hairloss and lymph node
enlargement, often confined to the head and neck areas. It may cause generalized lymph node enlargement and sometimes the skin infection signs affect the trunk or feet as well as the face.
