Everytime you do anything with a dog, you take a chance of something happening. You could put him on a swap out dog, etc. There are various ways to avoid things from happening. I'm not particularly concerned with losing a fang. The dog has 3 more to work with if that were to happen, and dogs with 3 teeth can win easily.

What about a first time out dog that's never been down that road before? All that work, and the dog isn't associating it with any outcome.
