Plain-English summary
A mixed female Shih Tzu puppy was brought to a clinic with a rigid mass that looked like two extra hind legs attached to her pelvis. X-rays showed that these extra legs were malformed and shorter than normal, along with two vulvas and two anuses, although only one set was functional. The veterinarians performed surgery to amputate the extra limbs, successfully correcting the puppy's condition. This case is notable as it is the first report of this type of congenital malformation in a dog in Iran.

Abstract
Congenital malformations are structural defects that occur in all species during fetal development. Pygomelia is a type of polymelia in which the redundant legs are joined to the pelvis. This abnormality is observed in both human beings and animals. A mixed female (Shih Tzu) puppy with a rigid mass resembling two pelvic hindlimbs was referred to a pet clinic in Mashhad City, Iran. In radiographic assessments, two extra hindlimbs stemmed from malformed pelvic bones and were shorter than normal limbs. Both extra acetabula were detected on the hemipelvis, with two extra coxofemoral joints perpendicular to the regular hip joints in the caudal direction. Also, two vulvas and two anuses were seen, but only one vulva and anus were functional. The additional limbs were amputated by surgery. This case is the first report of a dog with incomplete caudal duplication and successful correction of pygomelia in Iran.
