3 month old Maltese puppy

Discussion

Surgical findings:
A straightforward perineal hernia was observed on the left side, and was repaired routinely. On the right side, there was no obvious hernia, but there was evidence of abnormal musculoskeletal development (only a small remnant of the coccygeal muscle was identified, and there was no sacrotuberous ligament present). This necessitated reflection of the right superficial gluteal muscle into the right perineal area for reconstruction of the perineal musculature.
