This study aimed to evaluate the Doppler ultrasonographic features of ventral perineal artery of bitches during different phases of oestrous cycle. Sixteen pluriparous bitches were subjected to transperineal Doppler ultrasonography during different stages of oestrous cycle by confirming the stage by exfoliative vaginal cytotlogy (EVC) and vaginoscopy. The resistivity index (RI), pulsatility index (PI), peak systolic velocity (PSV), end diastolic velocity (EDV) and systolic/ diastolic velocity (S/D) were analysed. No significant difference was found between the Doppler velocimetric parameters of ventral perineal artery during different phases of oestrous cycle by trasnperineal Doppler ultrasonography.
