Atopic dermatitis is one of the most common and distressing skin conditions in dogs, causing chronic itch, skin damage, and significant welfare impacts. Understanding triggers and modern treatments can dramatically improve affected dogs' quality of life.
Chronic itch represents a profound welfare challenge. Dogs with uncontrolled atopic dermatitis may spend 20-30% of waking hours in itch-related behaviours — scratching, licking, rubbing — disrupting sleep, play, and normal social interaction. Skin damage from self-trauma creates pain layered on top of itch, and recurrent infections add further suffering. The condition is fluctuating rather than constant, with flares often tied to seasonal pollen peaks or pathogen exposure, creating unpredictable cycles of acute suffering. Psychologically, the chronic nature of untreated or poorly controlled CAD can lead to anxiety, irritability, and reduced tolerance for handling. Dogs may resist grooming or veterinary examination of affected areas. Long-term corticosteroid use — still common due to cost barriers to newer medications — carries its own welfare costs including polydipsia, polyphagia, weight gain, muscle wasting, and increased infection susceptibility. Tailored, multimodal management plans that minimise steroid dependence while controlling itch represent the gold standard for maintaining welfare in these animals.
