A five-year-old, male Dachshund is being prepared for emergency thoracolumbar spinal surgery. The owners found the dog dragging its hindlimbs about 4 hours earlier at 5 pm. The dog was noted to walk normally at 12 noon, but seemed wobbly at 2 pm. On your neurologic examination prior to any anesthetic agents, the cranial nerves and forelimbs were normal. There was some voluntary motor movement of both hindlimbs but the dog could not rise on its hindlimbs. A radiograph was taken with the dog under anesthesia.
