It is aimed to detect allergen determination via serum specific immunoglobulin E (IgE) for the first time in dogs diagnosed as Atopic Dermatitis (AD) from Samsun and vicinity within this present study. Twenty one dogs with different age, breed and gender diagnosed with AD based up on the Favrot's criteria. Serum samples of the dogs were analyzed by detection of serum specific IgE for determination of 20 different allergens. The effects of gender, age and the feeding routes for those 20 different allergens separately were analyzed. Based up on the grading of the allergens detected in 21 dogs with AD from Samsun and vicinity; results reflects that Dermatophagoides farinae was stated as first degree within a very high seropositivity rate (95%). Moreover, in varying degree of seropositivitiy rates of other allergens were also detected. Females showed statistically (p<0.05) higher positivity rate to the 20 th allergen, Ctenocephalides spp. more than males. Furthermore, we did not found any significant effects of age and feeding routes on the allergens in the dogs with AD (p>0.05). Dogs with AD from Samsun and vicinity had very high serum specific IgE levels against to the house dust and storage mites.
