As with lupus in humans, this autoimmune condition is one in which the body's defense systems begin to attack the dog's own body. The cause of lupus is unknown, but it does seem to be passed genetically. Symptoms of lupus include skin scabs or sores, especially around the nose in DLE; and for SLE symptoms include fever, weakness, neurological impairments, arthritis, and kidney issues.
Home Remedies: Sunblock or at least reduced sun exposure is important for dogs with discoid lupus. Omega-3 supplements, vitamin E, and niacinamide supplementation may also help your dog.
