Incidence of Canine Hypersensitivity in the Region of North Eastern Bohemia

The aim of the study was to determine the incidence of different types of hypersensitivity disorders in dogs in the region of North Eastern Bohemia in the period of 1994- 2005. In total 150 dogs were included in the study based on suspected hypersensitivity reaction. The incidence of hypersensitivity disorders in the broadly selected group of patients with dermatological problems was 3.5%. The most common diagnosis was atopic dermatitis (94 cases) followed by fl ea allergy dermatitis (80 cases) and food hypersensitivity (18 cases). In terms of breed predilection, the highest number of hypersensitivity cases were Boxers (100%) and French bulldogs (92.3%) which is signifi cantly higher proportion (p < 0.05) compared to Shar-Peis (50%) and signifi cantly even higher proportion (p < 0.01) compared to other breeds. In relation to age and sex, no signifi cant differences were observed in incidence of hypersensitivity disorders. Canine atopic dermatitis and fl ea allergy dermatitis were most commonly diagnosed between 6 months and 3 years of age. Sex predilection was not observed in any of the hypersensitivity reactions. Hormonal hypersensitivity was diagnosed in 4 patients over 6 years of age. Angioedema, rash and insect bite hypersensitivity was diagnosed in 8 acute cases where fast recovery was observed after institution of appropriate therapy
