Canine atopic dermatitis causes chronic itch and skin inflammation affecting millions of dogs, with newer biologic therapies offering dramatically improved welfare outcomes compared to older treatments.
Before modern biologic therapies, dogs with severe atopic dermatitis often lived in chronic misery - perpetually itching, self-traumatizing, and experiencing repeated secondary skin infections. Steroid use for control carried metabolic and hormonal side effects. The development of safe, targeted anti-itch biologics represents one of the most significant companion animal welfare improvements of the past decade. Yet many affected dogs remain undertreated because owners don't recognize chronic itch as a major welfare problem deserving treatment.
