As part of their "all-purpose farm dog" duties, one of the Swissy's many tasks on the farm was to herd and drive livestock. Therefore, they were bred for and still do possess a strong herding instinct. Axel is pictured here at 17 mos, the first time he ever even saw sheep (the closest he came before was cuddling in a wool sweater). I was stunned that he knew almost immediately what to do, without being told...when so seldom does he do what he is told half the time! That's why they call it instinct. In retrospect, that's probably why he also grabs my pant legs and sleeves when were out running and playing in the yard.
