That dog looks like a herder to me. Our belgian shepard IS a herder and believe me. He keeps his birds exactly where he want's e'm to be.
He never attempts to touch them tho. That is unless they don't move fast enough for him. He will then poke 'em in the butt with his nose. lol
It's a good plan tho. He does not let'em near the road and he doesn't let 'em wander off too far into the woods.
