Cystic endometrial hyperplasia-pyometra complex complicated with both ehrlichiosis and hepatozoonosis in a Rottweiler bitch

Cystic endometrial hyperplasia-pyometra syndrome is a very common uterine disorder reported in breeding bitches. This case report describes cystic endometrial hyperplasia-pyometra complex complicated with both ehrlichiosis and hepatozoonosis in a 21 kg, 3-year, 9-month-old intact Rottweiler bitch presented to the Veterinary Teaching Hospital, University of Ibadan with complaints of inappetence, vomiting, melena and swelling of the caudal abdomen around the pelvic entry which on aspiration was bloody. The bitch was said to have been mated by natural mating about 73 days prior to presentation at the clinic but showed no obvious sign of pregnancy. Ultrasonography revealed thickening of the endometrial wall with distended and anechoic sacs filled with heterogenous echogenicity which was later found to be due to pus accumulation in the uterus.
