John,
I totally agree with you about the reason for docking sheep but that wasn't the point I was making, my point was more on the cruelty side if things, it doesnt seem to effect the sheep, then why should it effect dogs.
As far as dog trainers in this area go, I don't know of any as I am only new to this area, I have had 3 GSP and found the best way to train them is with another well behaved good working pointer/ retreiver
cheers
Darryl
