For those who think the dog would run from an aircraft, there was a FSA article* a few years ago about a charter bloke in the top end who had a dog, "accustomed to aircraft" apparently, run into the prop disk.
As there was no phone around, he flew 20 mins to the nearest one, and on shutdown, checked the prop again and one blade could be rotated the full 360* in the hub.
Unfortunately, there aren't any guarantees with this kind of thing...
*And do you think I can find that article now??
