I still remember getting out first pair of border collies as a kid. Rounding up cattle went from an hour of frustration and running around, to a few whistles and a few minutes. Amazing animals, any herding breed.

I've always loved watching dogs work. My uncle raised cattle and would run dogs for it and he trained bird dogs to sell. Always amazed me to see them in action. Wish he was still around to get some advice.
