Canine atopic dermatitis (atopy) is a chronic allergic skin disease causing intense itching and skin damage. It is one of the most common and welfare-significant conditions in dogs.
Canine atopy causes chronic, often severe pruritus (itching) that significantly impairs quality of life. Affected dogs may scratch, lick, and bite themselves to the point of causing self-inflicted wounds, hair loss, and skin thickening. Sleep is disrupted, normal activities are compromised, and behavioral changes including irritability and anxiety are common. The chronic, relapsing nature of atopy means dogs may experience prolonged suffering if not adequately treated. Modern targeted therapies (Apoquel, Cytopoint) have transformed management and dramatically improved welfare outcomes for many dogs. However, these medications are expensive, and cost barriers mean many dogs receive inadequate treatment. Systematic monitoring of itch severity and quality of life using validated tools should be standard practice.
