DIPHALLIA AND POLYMELIA IN A DOG

A 5-month-old male mixed-breed dog with two penises and a third, rudim entary rear limb which was attached by a hemipelvis was presented. One month after it was adopted from an animal shelter, the dog developed a gross hematuria and inappropriate urination. Several years later, th e owners requested the dog be castrated. Ultrasonography reconfirmed t he presence of two normal kidneys, a right and left bladder, and two p rostate glands. Conclusions of the studies indicate that while the emb ryologic basis for development of these anomalies is not well understo od, they need not be incompatible with life.
