Hes not coming back till hes eaten it or stoped play with it, I just don't want him to get a bad habit, so when he gets a live one he will come to me with it not just eat/play
Work on the recall where you know there's no carcass's,when he's comes back go mental with praise.Shout,wave your arms,wrestle him,get him to jump up on you,just go mental so he knows when he comes back he get's a bloody good game with you and your better than the carcass.Treat's don't do no harm either,just small bit's of meat.What cross is it.?
