Chronic vaginal prolapse during pregnancy in a bitch.

A 4-year-old bitch was referred with chronic vaginal prolapse. It was first noticed during estrus, about 58 days prior to referral. Artificial insemination (AI) was performed twice after reducing the prolapse manually. Abdominal radiography (53 to 55 days after AI) was performed by the attending veterinarian and the bitch was determined to be not pregnant. Serum progesterone and estradiol concentrations were 1.38 ng/ml and 1.79 pg/ml, respectively. With the bitch under general anesthesia, the vaginal prolapse was partially reduced and a hysteropexy was performed. Six days after surgery, the bitch delivered a live male pup. It is recommended that bitches so affected should not be bred, and that those not required for breeding should be ovariectomized.
