A rare case of a double vagina in a young American Staffordshire Terrier bitch (Canis lupus familiaris). A case report.

The presence of congenital urogenital malformations is relatively common in bitches. However, cases of double vagina in the literature are scarce, and the ones reported usually accompany other urogenital defects. The vaginal anomaly was an incidental finding in the present case during a routine spay and was not accompanied by any other malformations. A detailed presentation of the diagnosis and surgical management of the double vagina is presented in the current paper. A 1-year-old nulliparous American Staffordshire Terrier bitch was presented for dysuria in the past 24 h. After inspection and palpation, a distended abdomen was noticed. Biochemistry, hematology, and urinalysis were performed. No other laboratory findings were noted besides mild hypocalcemia, hypoproteinemia, hypobilirubinemia, and increased lipase. During the ultrasonographic examination, a hypoechoic fluid accumulation was observed caudal to the urinary bladder in what seemed to be hydrocolpos. Exploratory laparotomy was recommended. Ovariohysterovaginectomy was performed, and the gross and histological findings were highly suggestive of a double vagina. The dog recovered from surgery uneventfully, and it was free of clinical signs six months after the surgery. To the extent of our knowledge, this is the first case of double vagina, without any other congenital defects, ultrasonography documented and surgically corrected, in a young bitch.
