In this case, I wanted him to figure out how to open up a bag that has been twisted closed (no ties or knots) and see if he can unwrap it to get a treat out without biting through the bag or otherwise tearing it.
Interestingly enough, he didn't even try to rip the bag. It was as though he just followed the scent down through the bag, trying to move the bag out of the way to get to the goodies inside.
I captured this on video. It is embedded below.
