Riverside with cattle Якоб Филипп Гаккерт (1737-1807)

The picture has something of this: cattle, cow, mammal, livestock, landscape, agriculture, dawn, outdoors, pastoral, farm, countryside, cavalry, nature, rural, sunset, pasture, bull, sky, tree.
Perhaps it’s a painting of a couple of cows in a wooded area next to a body of water with a man and a dog on the other side of the painting.
