#### **Abstract**

Sexual-cycle abnormalities are an important cause of infertility in bitches, with disorders such as anestrus, split estrus, and persistent estrus having varied etiologies. Sexual-cycle abnormalities in bitches may be addressed as follicular- or luteal-phase disorders. However, pet owners should have a good working knowledge of the sexual cycles of their animals in order to better understand these disorders.
