title: The ACVD task force on canine atopic dermatitis (XI): the relationship between arthropod hypersensitivity and atopic dermatitis in the dog.
abstract: The relationship between arthropod allergen hypersensitivity and the development of canine atopic dermatitis (AD) is unclear. It has been shown that dogs with AD are more likely to exhibit positive intradermal reactivity to flea allergens than non-pruritic dogs from the same flea-endemic geographic region. Also, dogs in a flea endemic region are four times more likely to suffer from flea allergy dermatitis (FAD) and AD than from FAD alone. These results provide indirect evidence to support the hypothesis that, in the canine species, atopy predisposes to the development of hypersensitivity to flea allergens and eventually to FAD. A causal relationship between insects other than fleas and canine AD has not been identified with certainty.
