The day on a farm starts so early that it's easy to imagine that you'd get worn out pretty quickly. Unless you happen to be a border collie.
This border collie either paced itself all day, consumed an energy drink (kidding ... please do not let your dog consume an energy drink) or just started its day, but the dog is so very pumped to spread some hay. The dog's farmer companion can't even keep up with the pup! The hay is barely on the pitchfork before the border collie has yanked it off the truck and shaken it around the ground.
This seems like an efficient way to spread hay, too. The border collie gets to expend some energy, the human just has to stand on the bed of a truck and the hay goes exactly where it needs to. After this, maybe they go and sit on the porch and admire their hard work. Or they go and herd sheep. Seeing the energy level of this dog, it's probably sheep herding.
