just started mine he's just over twelve months, he missed his first two or three slips, more down to my error than his though. and our land has been hammered so theyre well shy and not far from cover. he has had one on each of the last three trips out though, just letting him have one and leave it there. but my mates collie whippet has been out with us everytime and hasnt had one on the lamp yet from as many slips as mine, but has had two in the daytime. every missed rabbit shouldteach them something though, he is already slowing down when he's on them, to start with he was more like a train.
