As the owner of a border collie I think this is a really good idea. As a pup our collie used to eat the reticulation, plants, outdoor furniture etc, when we were out even though he got a lot of attention when we were home plus a long walk each day. Eventually they learn what they can and can't chew so this is a good way to preserve everything in your backyard! Our outdoor setting still has chew holes in it...

And obedience training is a definite for border collies. He will love it and so will you!
