You'd have problems taking a very sick dragon to the vet. I mean, if it can at least walk under its own power that's one thing, but you'd need a Very Large Truck for one that's out cold. And a crane to put it on the trailer. Then you have to find a vet who's willing to look at it. Not all of them will treat reptiles, or large animals of any sort. Also, they have to have a parking lot that will take your truckload of dragon (ours doesn't).

Also, the food bill would be prohibitively large. Can you imagine how much meat you'd need to feed a dragon for a year? Now think about current grocery prices. The dragon won't pay out of its hoard (by definition—you hoard a hoard), so it's all on you.

Don't even try to think about cleaning up what comes out of the other end.
