Several years ago I had a Border Collie, Meg who met a sad end one winter`s night with a pack of coyotes. Anyway, Meg had such a strong "eye" that the cows would keep a distance of 50 yds or so until I cut the bales strings & told her to get back in the truck. One of my other BC`s, Ben, did a pretty good job but not as good as little Meg.
Murphy is my new guy & he`s working pretty good so far.....time will tell.
