Don't like them either(bet some right Muppets have them), but I know a dog that got a few zaps to stop it chasing vehicles, better than getting ran over...
Guessing Morton's would if there was nowt doing/better.
Wouldn't want a run picker either, but I've never thought a dog concentrating on the job in hand and not a rabbit sitting a field away was run picking..
What is there to get, someone asks what any lurcher is, the quickest easiest way to answer is to name it's cross.
Bull grey
Whip grey
"Coursing bull"
I'd have a coursing collie in the future.....but call it a lurcher
