Cloacal malformation in a 5-month-old male dog.

A case of a developmental cloacal anomaly is described in a 5-month-old male puppy. The animal had a unique combination of anomalies: confluence of the urethra and rectum into a common tract with a single perineal opening, atresia ani, and 3 genital anomalies, namely, a perineal hypospadias, penile hypoplasia with ventroflexural curvature, and a scrotal cleft. Surgical correction was successful, with fecal continence maintained and no urinary tract infections occurring during long-term follow-up.
