Pemphigus in dogs is an autoimmune disease, where the immune system mistakenly attacks skin cells, causing blisters and crusts, with most cases being idiopathic (no known cause) but often triggered by genetic predispositions (like Akitas, Chow Chows), certain drugs (antibiotics, flea/tick meds), UV light, infections, or underlying cancers. The condition stems from autoantibodies targeting proteins that hold skin cells together, leading to separation and visible lesions.
