[Food hypersensitivity dermatitis in the dog: diagnostic possibilities].

[Article in German]

Dogs with food hypersensitivity usually develop chronic pruritic dermatoses virtually indistinguishable from atopic dermatitis. These reactions are often called food allergy but the pathogenesis is poorly characterized. Several studies have addressed the incidence of canine adverse reactions to food but the outcomes were conflicting. The gold standard for the diagnosis of such a condition is the restricted dietary trial and the subsequent provocation challenge. Some attempts have been made to develop serological tests but none of these tests accurately predicted canine food sensitivity. The aim of the present study was to determine the incidence of food hypersensitivity dermatitis and to evaluate a newly developed serological test for the diagnosis of food allergy in dogs. Only 9% of 55 dogs with dermatological signs compatible with food hypersensitivity or atopic dermatitis have been diagnosed as food hypersensitive dogs. The repeatability of the serological test has shown to be insufficient.
