A herd is a bunch of animals â or people who act like a bunch of animals. It's also a verb â when people herd animals, they try to keep them moving in the same direction. A herd usually refers to a group of animals with hooves, like cows or sheep (meat-eating animals like wolves cruise around in packs). On a farm, sheepdogs are in charge of herding the herd of sheep. Herds of buffalo roam the plains.
