Autoimmune disease is referred as occurrence of antibodies formed by system. It responds against healthy tissues and cells of the body. If the antibodies get deposited deeply in the body, it will remain severe. It deposits into skin layers and affects the entire body system. Acantholysis is the common sign of Pemphigus. In this condition, the skin cells break and separate down since tissue bound antibody bonds in space between cells.  There are four kinds of Pemphigus that dogs get easily affected. They are Pemphigus vegetans, Pemphigus vulgaris, Pemphigus erythematosus and Pemphigus foliaceus.

 

In Pemphigus foliaceus, the antibodies bonds with the top most layer of the epidermis. You can see blisters on the healthy skin of dogs.  Pemphigus erythematosus is a commonly seen autoimmune disease in majority of dogs. It is almost equal to Pemphigus foliaceus. However, it is less afflictive.

 

Pemphigus Vulgaris causes severe and deeper ulcers. It is because the antibody deposits deep inside the skin. One of the rarest condition is Pemphigus vegetans. It affects only the dogs. It remains gentle than Pemphigus Vulgaris. It causes mild ulcers to the dogs.
