Even a highly trained dog sometimes is not perfect. In his training, his handler was accustomed to using a tennis ball to reward him in play. Apparently the tennis ball was providing a lot more motivation than the trainer and handler had counted upon.
One day, Shockey refused to relinquish the ball. Training had given the handler a procedure to follow under these circumstances, and eventually he recovered the tennis ball… sort of.
In the process of arguing with his handler about who would retain custody of the ball, Shockey gave the ball a pretty savage chewing. A dog's big back teeth are designed to shear off chunks of his prey so that he can gulp them down. The big piece is what the handler obtained. All the other pieces were sheared off and gulped down.
Fortunately, I was able to retrieve the debris by the simple expedient of inducing vomiting. No surgery was needed to extract it (before or after a blockage occurred). The irony of this situation is that we had to do this on a night emergency basis because I had not yet finished preparing the officer's emergency kit for dealing with accidental drug ingestion. If I had finished it (and now I have), the officer could have used his kit to induce vomiting right at home.
Of course, the up side is that the officer got to see a real-life demonstration of how to induce vomiting… and watch me clean it up. Ah, yes, seven years of college (sigh).
