Funny how we were just talking about this. The story is that the owners pit bull got out of the yard and lunged at the neighbor, who shot at him 5 or 6 times with a .380. The dog presented to me about 30 minutes later ambulatory, alert, non painful with his left eye, conjunctiva, and eyelids swollen, bruised and bleeding. Upon further examination there was an entry wound through the upper eyelid, an exit wound below his left ear, and a grazing wound in front of his left shoulder. The globe and cornea were intact but the front part of the eye was filled with blood, most likely from the force of the bullet passing through the lid a few mm away. The bullet entered the cheek, struck the jaw cracking it, an exited the neck. No lead or jacket fragments on X-rays, so I'm assuming fmj or tmj most likely.
The moral of the story is that pit bull heads are mostly muscle and bone, and it is harder than you think to get a CNS hit when the brain is tiny and only about 1/4 of the head. Remember I only see the lucky ones. The radiograph is taken pointing down towards the top of the head. The small oval shaped thing towards the bottom is where the brain is, the rest is muscle and bone.
