Discoid Lupus Erythematosus (DLE) and Nasal Solar Dermatitis are not the same, although they can appear similar and sometimes overlap in clinical signs, especially on the nose or face of dogs and horses.

Both conditions tend to occur on the nose, especially where the skin is lightly pigmented. Sunlight can aggravate both and diagnosis sometimes requires biopsy to distinguish them clearly.

What is Discoid Lupus Erythematosus?

Discoid Lupus Erythematosus (DLE) is an autoimmune disease, also known as Lupus. DLE creates a skin condition in dogs that typically causes a loss of colour, (discolouration), on the hairless part of the nose, such as a black nose fading to grey or pink.

The surrounding skin may also be affected, and the discolouration can be accompanied by ulcers and bleeding. Symptoms of DLE can be missed and remain undiagnosed until the disease has reached an advanced stage. Two types of lupus occur in domestic dogs - discoid lupus erythematosus (DLE) and systemic lupus erythematosus (SLE).

What is Nasal Solar Dermatitis?

This type of collie nose, which worsens in the summertime, is caused by too much sun exposure. Nasal Solar Dermatitis can create weepy, crusty skin on the nose. Although it can affect different breeds of dogs, it predominately affects Collies, Australian Shepherds, Shetland Sheepdogs, and other related breeds. If left untreated, the crusty skin can start on the end of the nose, but then travel up over the bridge, and to the mouth and eyelid area.

Symptoms of 'Collie Nose'

  • Paleness of the skin on the nose
  • Skin redness
  • Skin scaling and flaking
  • Skin erosions (sores
  • Skin ulcerations
  • Skin crusting
  • Scarring
  • Painful to touch

If you suspect either condition in a dog or horse, it's best to consult a vet for an accurate diagnosis and appropriate management plan.

Prevention 

The first step to preventing Collie Nose is to keep the dog out of very bright sun, limiting exposure to UV light, as well as covering the area with a dog-safe SPF sunscreen. 

Diet also factors into prevention and aiding the healing process. Feeding your dog raw food improves the whole digestive system - when you’ve got the dog's stomach working the way nature intended, everything improves. Removing what shouldn’t be in a dog’s food intake, is a sure way to look after, and improve your dog’s coat and skin.

Any canine affected with Collie Nose benefits from being fed a natural, raw diet, with no packaged or tinned or containing preservatives. We’ve seen amazing results with our recommended diet in dogs who have had skin conditions for years!
