The aim of this study was to determine the relationship between age and prostate size and measure and characterize the prostates of French Bulldogs through two-dimensional and Doppler ultrasound. Thirty-three healthy French Bulldogs were used in this study. The dogs were divided into three groups of 11 animals according to age: 8 to 19 months (group 1), 24 to 36 months (group 2), and 48 to 72 months (group 3). The animals were evaluated once with ultrasound to obtain the following: the two-dimensional sonographic appearance of the prostate, prostatic dimensions, and characteristics from colored Doppler (perfusion characteristics, diameter, and number of pixels of the vessel) and spectral Doppler (wave morphology, resistive index, and pulsatility). There was a high positive correlation between age and prostate volume (r = 0.906). The prostatic volume gradually increased with age (P
