Meningomyelocoele in a Dog

An 8-month-old English Bulldog with focal and urinary incontinence was examined before and after death. There was nonfusion of the dorsal laminae of vertebra L, in the midline. Through this defect a small meningomyelocoele, and the terminal part of the spinal cord, emerged from the spinal canal. The clinical signs were attributed to damage of both pudendal nerves or their spinal cold segments. The dog had normal spinal cord function to all limbs.
