true, you cant put in ,what nature left out,? some dogs will want kill at 18 months old , others 2-3 year old . I had lurcher x lurcher bitch didn't want to know the sharp end until she was 3 year old, she got nipped at 18 months old and never bothered again , so just ran rabbits with her . then one night when she was near 3 year old she killed a fox, I was shocked then after that she kill them regular , so you never know you cant always right them off .?
Shes sister did the job the other night so nature was good to her
