I had a couple carrying a profusely bleeding pit bull careen into the hospital. The dog was sneezing and snorting blood everywhere, but the tail was wagging a mile a minute. The owners were both crying and generally freaking out. I took a quick look at the dog and determined that the damage was not too bad: the dog was a young healthy dog that was apparently happy and stable in spite of his injuries. The owners kept freaking out and I had a hard time getting sense out of them. I finally grabbed the husband by the shoulders and looked into his eyes and said, "It's not that bad...I should be able to put that back together." The both settled down and relayed the story.
Apparently, they had left a loaded shot gun leaning against the wall....not locked up, not in a gun rack, just leaning against the wall. The happy dog's overactive tail knocked the gun over. When the husband picked up the gun, the dog was investigating the hubbub when the gun went off, catching his nose. Given the (relative) lack of damage, it looked like most of what got the nose was scatter. It was bleeding like crazy, but there was enough tissue that I could get it all back together.
After I fixed the dog, I ascertained that there were no children in the house. As nice as the owners seemed, if they had kids, I would have reported the accident. While I would shake my head and be a little down trodden if I heard about another animal in the house getting accidentally shot, I would have had a hard time living with myself if a child had been involved. This may not be completely legal per se, but if it isn't, it is a clear example of what is right versus what is legal. Human physicians don't really have this quandary: they are required to report gun shots.
A couple of weeks later, I got a thank you letter with pictures from the owner. There was a picture of a dog happily grinning at the camera as well as a close up of the healed nose.
