Great dog work!  Makes me realize how much work I have to do with my dog yet. I think he is a lot smarter than I am but we will teach each other a lot in time I hope. We moved ewes and let all of them out with their lambs and Jack moved them a quarter mile tonite to another paddock. It would have been suicide without a dog. He saves me so many steps everyday. I would rather walk sheep than haul them any day!!  Looks like your dogs are having fun working their hearts out. It's good to see that!
