The "bunnies" are actually white trash bags and they chase them because they chase anything that moves(literally). They DO catch rabbits, squirrels, possums and unfortunately cats and kill them. If it is small and runs, they will kill it. You can't teach them not to and you don't have to teach them to do it. It is so bred into them. It is like labs and water or pointers and pointing.

Lure coursing was actually started 20 years or so ago because people were aghast at open coursing(hunting live jackrabbits) it is a controlled and "clean" way to let the dogs do what they were bred to. There are still people who open course, mainly out west where there is an overpopulation of rabbits and enough open space. I would love to do it. It would get ME in shape too!
