Tie a stick to their chest and neck sticking out 7" in front of their nose and then put a hot dog weenie on the end of it.

Find a firecracker stand and purchase them lil paper poppers and when the dog least expects it, throw one at his butt.

Tie a bunch of coke can to his tail and slap him on the keister.

Get up to a 25 mile per hour speed in your truck with the dog dangling out the window then drop him and hit the brakes, this is called the inertia method.

Two words, butt rocket.

No seriously pu him in good sign and let genetics take over, if he won't hunt, find another dog that will.
