Advances in ovulation timing in the bitch

Abstract

In order to understand how ovulation timing (OVT) works, it is important to understand the basic physiology of the estrous cycle. Ovulation timing consists of vaginal cytology, vaginal speculum examination, progesterone and luteinizing hormone (LH) concentrations. Once an understanding of basic OVT is obtained, this knowledge can be used to assist with breeding management decision making.
