Collie nose problems may result from either one of two causes. Firstly, Discoid Lupus Erythematosus , an autoimmune disease which can eventually lead to squamous cell carcinoma  if untreated or secondly a lack of pigment at birth that can then lead to a gradual removal of the nose pad resulting eventually in ulcers which can also lead to squamous cell carcinoma.

What is Discoid Lupus Erythematosus
Discoid Lupus Erythematosus (DLE) is a skin condition of dogs that typically causes a loss of color (discoloration) on the hairless part of the nose. A black nose may fade to gray or pink. The discoloration can be accompanied by ulcers and bleeding. The surrounding skin may also be effected.

Lack of Pigment
Some dogs with less pigment on the nose area, after exposure to the sun, may experience a blistering of the nose. Collies and related breeds can get a weepy, crusty dermatitis on the nose if they spend too much time in the sun. Treatment for Collie nose involves keeping the area protected as it is difficult to keep a dog out of the sun. It is not only Border Collies that suffer from these nose problems but also Shetland Sheepdogs and Beagles.
