if it works for you... I dont mind at all. I know a lot of people who have barking BCs, mine does bark at our gardeners, so we ended up just introducing him to the guys and allowing him to get used to the sounds. He is also kept inside when the gardeners come, to avoid any bad situations.

I wouldn't use a bark collar ever on Gonzo, cos Im almost positive itd freak him out and make him really hand shy and scared. Borders are hyper sensitive, especially mine. and I always worry that the collar would malfunction or shock him for no reason, or what if a burglar came into our yard and he wanted to alarm bark or scare him off? I also think its natural and okay for dogs to bark at things that startle him, to alarm his owner... just not in excess. my dog has learned that thru training and correction from me and\my family, not thru a collar.
