Monitoring the treatment outcome of canine cystic endometrial hyperplasia-pyometra complex (CEH-P) is essential to identify non-responding patients that might require a rapid intervention to avoid life-threatening conditions. Uterine arteries Doppler characterization will probably contribute to monitor medically treated CEH-P but no further research has been conducted in this regard, so far. Therefore, the aim of this longitudinal prospective observational study was to evaluate uterine arteries resistance changes in the medical treatment of bitches with CEH-P. Twelve diestrous bitches suffering from CEH-P were treated with a combined protocol of cabergoline, cloprostenol and antibiotics. The animals were clinically and ultrasonographically evaluated before the beginning of treatment (day 0) and on days 3, 7, 14, 21 and 28. The widest cross-sectional diameter and luminal diameter of uterine horns were measured, as well as the peak systolic velocity (PSV) and end diastolic velocity (EDV) of uterine arteries. Resistance index (RI), pulsatility index (PI) and notch deep index (NDI) were calculated. On day 3, 9/12 animals showed clinical improvement. In all these bitches, the widest cross-sectional diameter (P
