need a dog sometimes to push cattle....already have a german shepard for home protection ..my cows are calm, and can call them to barn in general when needed...got into my hay pasture today and had a 2 hour time getting them out...reminded me of when my dad had a blue heeler to drive cows...dog would need to get along with my home dogs but i would train him on driving cows..had some experience with border collie, blue heeler in the past...love to halve any opinions
