Atopic dermatitis is a common chronic skin condition in dogs causing intense itching and secondary infections. Modern treatments have transformed quality of life outcomes for affected dogs.
Chronic atopic dermatitis causes significant suffering through relentless itching, secondary infections, and the disruption to sleep, social interaction, and normal behaviour that severe pruritus produces. The welfare impact of chronic itch is easily underestimated by owners who may view scratching as minor, but dogs with severe atopy can spend many hours each day in itching and licking behaviour that profoundly reduces quality of life. Modern treatment with IL-31 inhibitors and Janus kinase inhibitors has transformed outcomes, providing fast and effective itch relief that allows dogs to return to normal behaviour within days. Long-term management combines disease-modifying medication, allergen avoidance where possible, skin barrier support, and prompt treatment of secondary infections. Allergen testing and immunotherapy offer the possibility of reduced medication dependence over time.
