Dog Skin Allergies and Atopic Dermatitis

Canine atopic dermatitis (CAD) causes chronic itching, skin infections, and significantly reduced quality of life for millions of dogs worldwide.

Key Facts

CAD affects 10-15% of dogs globally and is among the most common reasons for veterinary visits.
West Highland White Terriers, Labrador Retrievers, French Bulldogs, and Golden Retrievers are predisposed.
Allergens include house dust mites, pollens, mould spores, and food components.
Skin barrier dysfunction allows allergen penetration — maintaining skin barrier health is a key management goal.
Targeted therapies including oclacitinib (Apoquel), lokivetmab (Cytopoint), and ciclosporin provide effective control.

Welfare Considerations

Dogs with CAD experience chronic pruritus — itching — that is deeply distressing, disrupts sleep, and causes secondary skin infections from self-trauma. The constant itch-scratch cycle is welfare-compromising in its own right; secondary pyoderma adds pain to the presentation. Untreated or poorly controlled CAD dramatically reduces quality of life. Modern targeted therapies have transformed outcomes — oclacitinib and lokivetmab provide rapid, safe itch control without the long-term side effects of corticosteroids. Management is lifelong and multimodal: allergen avoidance, regular bathing, skin barrier support, and targeted medication all contribute to achieving acceptable quality of life.

What You Can Do

Seek specialist dermatology referral if initial treatment for your dog's skin condition is not achieving control.
Bathe your atopic dog regularly with veterinary-recommended shampoos to reduce allergen load.
Discuss modern targeted therapies with your vet rather than relying long-term on corticosteroids.
Use a quality-of-life questionnaire designed for pruritic dogs to assess and track your dog's welfare.
