Visit to the veterinary doctor for different reasons constitutes an unpleasant/negative or perhaps stressed experience for the dog. The stress could modify the physiological function and mask the symptom of an illness, or make the dog aggressive (1). Aims: Comparing the endocrine and behavioral response of dogs during the visit to the veterinary hospital and during activities in other places that are not related to stress (workplace, park). Materials and Methods: Six dog were taken in consideration, as indicators of stress there were used urinary cortisol, and behavioral observations. Results: Five of six dogs got high values of urinary cortisol after the visit to the veterinary clinic comparing with the values obtained in working spaces/park – areas that were familiar for dogs. Behavioral data’s have indicated a hesitating behavior at the entrance of the clinic and also in the examination room for all dogs, but the levels of intensity range individually for each dog. The results of the „Clinic Dog Stress Scale” classify behavior of dogs in following categories: 1 dog had score of 1 point that means a calm, relaxed dog; 2 dogs-3 points that means a middle level of stress, the dog is tense but cooperative; 2 dogs got 4 points-very tense, difficult to maneuver, and one dog 5 points that means a high level of distress.. Conclusion: Studding behavior relating with stress and the endocrine response at the veterinary visit it has importance for animal, owner and veterinary doctor. There is also a correlation between the stress manifestation and urinary cortisol.
