The fence may act as a correction aswell. Everytime Brock wants to dig or attact the other dog, he will be warned & then zapped.

It just might work.
Doesn't sound harsh at all. We have done that, Our whole place is surrounded by electric fencing as well as the other fence. We live out in the country and we felt we had to do that so no wild animals gets into our yard. Had to make sure my ducks and chickens were safe.

Problem is Brock doesn't care. It did work for awhile but I guess Brock just got use to it. He just goes through it shock and all. There are stronger ones, but that just seem too cruel. Good idea though, if I didn't have a hard headed Dane.
