There are many autoimmune diseases, and they all vary in impact to the dog and progress at their own rates.

Article body

Dogs suffering from autoimmune diseases of the skin may experience a variety of symptoms, including persistent itching and scratching, lesions, wounds, blisters, and other skin damage, as well as loss of skin pigment.[1] Two cases of autoimmune diseases that are often found include Discoid lupus erythematosus (DLE) and Pemphigus. DLE can develop into Systemic Lupus Erythematosus (SLE).[2] Another autoimmune skin disease which can occur in dogs is vitiligo. The exact prevalence of this disease in dogs is currently unknown, as it is likely under-reported.[3]

In addition to humans, Vitiligo can be found in a variety of animals, including cats, horses, and dogs. Vitiligo is a type of autoimmune disease that damages melanocytes in the skin, lips, and oral cavity. Melanocytes are cells that contain pigments such as melanin. These pigments give rise to an organism's phenotype, which determines skin and hair color.[4] Melanocytes are also found in other parts of the body, such as the oral mucosa, eye, cochlea, and the meninges. In addition to Vitiligo, there are other autoimmune diseases that target melanocytes, such as Vogt-Koyanagi-Harada (VKH) syndrome, and Uveodermatological (UDS) syndrome.[5]

When pemphigus occurs in humans, the skin will begin to blister due to antibodies attacking the adhesive proteins in epidermal cells, which causes them to separate. Different types of pemphigus can be identified based on the depth of separation present in the skin. Many forms of pemphigus can be identified in dogs using methods similar to those employed for humans.[6] In infections caused by Pemphigus vulgaris, lesions are usually evident in the oral cavity of the dog.[7] Sometimes symptoms are characterized by lymphadenopathy, which is characterized by loss of appetite, weakness, fever, and in rare cases, sepsis.[7] Pemphigus foliaceus usually affects areas of the ears and face.[7] Early symptoms are characterized by depigmentation of the nasal palate, dorsal cleft in the mouth, the ear, and the periocular area around the eye. Itching, pain, and weakness of the body have been observed in some cases.

The immune system functions in many ways to eliminate foreign substances and particles introduced to the body. This revolves around T-cell differentiation, where mature T-cells with receptors for non-self cells target foreign antigens and act with other cells to dispose of them.[8] There are two mechanisms of tolerance found in the immune system. The first mechanism is positive selection by the thymus, where only T cells are selected. T cells recognize peptides in the Histocompatibility Complex (MHC). Foreign antigens possessing MHC molecules will then be
