"Picaro," the horse from Spencer, Mass., brought last week to the Cummings School's Hospital for Large Animals at Tufts University with gunshot wounds, will undergo additional testing and a possible second surgery today.

A surgery on Friday to remove bullets from Picaro's head revealed that the horse had sustained several hairline fractures to his jaw that were not apparent upon initial examination. Picaro spent the weekend recovering from that procedure, in which surgeons also removed his severely injured right eye and bullet fragments.

A surgical procedure might be required to fix his lower jawbone and allow it to heal.

Picaro's team of veterinary surgeons, anesthesiologists, interns, residents, technicians, and fourth-year students will examine the extent of the mandibular fractures tomorrow using the Cummings School's new 16-slice computerized tomography (CT) scanner. Pending the outcome of the CT scan, the team will then recommend the best course of action for the horse
