Dog Atopic Dermatitis: Immunotherapy and Long-term Management

Canine atopic dermatitis causes chronic pruritus and recurrent skin infections. Allergen-specific immunotherapy offers the potential for long-term reduction in allergen sensitivity.

Key Facts

Atopic dermatitis affects 10-15% of dogs and is the second most common skin disease
It is caused by hypersensitivity to environmental allergens including house dust mites and pollens
Intradermal or serum allergy testing identifies allergens for immunotherapy formulation
Allergen-specific immunotherapy achieves good or excellent response in 50-70% of treated dogs
Oclacitinib (Apoquel) and lokivetmab (Cytopoint) provide rapid symptom relief

Welfare Considerations

Atopic dogs experience constant pruritus that disrupts sleep, social behaviour and wellbeing. Chronic scratching causes secondary skin infections, ear disease and skin trauma. Immunotherapy requires 9-12 months of consistent injections or sublingual drops before maximum benefit is achieved, demanding significant owner commitment. Combination approaches using immunotherapy alongside anti-pruritic medication provide symptom control during the desensitisation period. Regular skin and ear monitoring with prompt treatment of secondary infections prevents chronic structural damage.

What You Can Do

Request allergy testing referral if your dog has recurrent skin or ear problems from age 1-3
Discuss allergen-specific immunotherapy as a long-term management option
Use oclacitinib or lokivetmab for rapid relief while immunotherapy builds effect
Implement house dust mite reduction measures — regular washing of dog bedding at 60 degrees
Treat secondary skin infections promptly to prevent antibiotic resistance development
