PATHOLOGY KEY POINTS

Atopic dermatitis (AD) is a common, genetically predisposed, inflammatory and pruritic allergic skin disease1. It is associated most commonly with IgE antibodies to environmental allergens1.

AD is one of the most common cause of canine pruritus, along with flea allergy dermatitis2.

The prevalence of atopic dogs in the general population is hard to estimate but could be around 10% of 1-3 year-old dogs2,3 and up to 30% in dogs with skin disorders2.

DIAGNOSIS, ASSESMENT AND PROGNOSIS

AD is a chronic relapsing condition usually requiring life-long therapy5

 

Ruling out of other skin conditions (ectoparasites, microbial infections, food intolerance, flea bite allergy, etc.)1

Historical and clinical features of the condition  (age at onset, living environment, affected areas, corticosteroid-responsive pruritus, etc.) 1,3,4

Assessment of skin reactivity by IntraDermal Testing (IDT) or detection of IgE by Allergen-Specific IgE Serology (ASIS) testing1,5
