Elsa pushes up some cows through deep snow.  I'm not giving her direction beyond her first "Get 'em up!" partly because I'm breathing so hard from walking through the deep snow!  She does gather them, even recovering the one I thought she had left.  She follows them around the corner of the road, and then comes back to check on where I am.  Typical English Shepherd behavior!  Lucas is shown just following our cows down the road while Elsa and I ride in the pickup!  There's no technique there but make sure they continue to walk down the road.  Easy duty!
