I have always been told that animals must learn to kill.
Our female, we got as a puppy, has always 'instinctively' killed animals. No play involved either. She chases, kills as fast as she, can then eats as fast she can.
Both my wife & myself don't encourage it, but for me (not my wife) watching her do it with the bunnies was like watching a discovery animal scene of a lion chasing her prey. I remember it so vividly, like she was in slow motion, she chased the 7 or so bunnies, they dodged & ducked and they dog adjusted to every move. No anger, no blood thirsty ravaging, just like a wild animal she was just catching food but with grace & beauty. We only saved one bunny. It was actually beautiful watching it (except the killing part). She did it quickly and efficiently as she could. Our male has not a clue to killing and ends up getting all bit up (stupid dog!)
It minds me of someone taking a street Ferrari out a track racing with other cars, seeing it work as what God intended the design to do. Poetry in motion, I guess what Lure Coursing must be like. I can tell you what it was like, or see pictures, but seeing it in person is different.
