The purpose of this study was to determine the normal parameters of the renal arteries in German Shepherd dogs in order to use these values in clinical studies and interpretation of the results. In this study, 24 healthy dogs of the breed German shepherd, including 11 female dogs (45.8%) and 13 male dogs (54.2%) were examined with doppler ultrasound. The average age of dogs was 2.7 years with a standard deviation of 1.07 (minimum age of 9 months and maximum age of 15 years). In each case, renal artery doppler parameters were measured and normal values of doppler parameters in renal arteries were measured. In the main renal arteries PSV mean was 84.07 cm/s and EDV mean was 44.46 cm/s. In intrarenal arteries mean PSV was 64.81 cm/s, the mean EDV was 33.03 cm/s, the mean RI was 0.54, and the mean AT was 36.53 m/s. The results obtained in this study are the normal parameters of renal arteries in healthy German Shepherd dogs, which can be used in clinical examinations and interpretation of the results.
