To spunkadelic,
I too, had a rough colllie.......a blue merle.............on our farm. They are great dogs. Tried to get him to herd our sheep, but after hubby calling from him from one side ,and me from the other - - - he looked at us both and trotted off home. Like saying to us both " Hey you may think I am a herder, but I only look like one !"
regards Mich
