Reproductive lesions are commonly seen in small animal practice. This study aimed to assess the reproductive disorders in bitches and queens. During the period from March 2013 to March 2015, 7 bitches and 28 queens of different breeds and ages (7 months up to 13 years) were collected from Alexandria Veterinary Medicine Directorate and Alifa Vet. Clinic, Alexandria, Egypt. They were examined clinically and by ultrasonography then ovariohysterectomy was performed for affected cases. Tissue specimens from uteri (n=35) and ovaries (n=20) were collected for both gross and histopathological examination. Results revealed that the most commonly recorded pathological conditions in the examined uteri were chronic endometritis (cats 67.85%, dogs 50% ) followed by uterine neoplasms (cats 10.71%, dogs 37.5%), acute endometritis (cats 14.28%, dogs 12.5%) and disturbance in circulation (cats 7.14%). Cystic Ovaries was the most prevalent pathological conditions among the recorded ovarian lesions (cats 35.29%, dogs 50%) represented mainly by follicular cysts (cats 35.29%, dogs 16.66%), cystic corpus luteum (dogs 16.66%) and cystic rete ovarii (dogs 16.66%) followed by ovarian neoplasms (cats 35.29%) represented mainly by papillary cystadenoma (29.41%) and Granulosa theca cell tumor (5.88%) followed by persistent corpus luteum (cats 11.76%, dogs 50%), circulatory disturbance (cats 11.76%) and oophoritis (5.88%). In conclusion, the female reproductive disorders were significantly recorded in cats than in dogs. The uterine lesions were the most frequent estimated affections, than while the ovarian lesions were found the second. Mostly, animals with uterine lesions were associated with ovarian lesions particularly, cystic ovaries.
