Our veterinary dermatologists routinely diagnose and manage autoimmune skin diseases. These disorders should be suspected if pets have blisters, ulcers or crusts on the skin or near the mucous membranes or if their skin has lost or changed its pigment. Skin biopsies are required to confirm the diagnosis and successful treatment requires the usage of medication to suppress the immune system. Pets with autoimmune skin disease require frequent medication adjustment and they must be carefully monitored in order to avoid medication side effects.
