In this study, clinical and laboratory findings along with serum IgE, IgA, IgM and IgG concentrations were determined in stray dogs (healthy and with dermatological problems). It was determined that skin lesions were localized in the rate of 69.8% (n=44) and generalized in the rate of 30.2% (n=19) of sick animals. Serum IgE concentration in stray dogs with dermatologic problems was significantly higher (P<0.001) than that of healthy dogs whereas serum IgM and G concentrations were significantly lower (P<0.05). It was evaluated that, serum total immunoglobulin concentrations could be useful in making contribution to differential diagnosis of skin diseases in stray dogs.
