Acute surgical intervention for a depressed skull fracture causing a laceration to the brain parenchyma from a bite wound in a dog.

A 5-month-old spayed female mixed breed dog was attacked by another dog causing multiple fractures of the left calvarium with a fragment penetrating through the gray matter of the parietal lobe. Surgery was performed to remove the bone fragment. A 6-month follow-up showed dramatic improvement in neurologic status.
