Attributed to John Woodhouse Audubon – A Young Bull National Gallery of Art (Washington)

The picture has something of this: cattle, cow, mammal, livestock, agriculture, bull, farm, calf, beef cattle, pastoral, pasture, grassland, animal, milk, grass, horn, soil, wear.
Perhaps it’s a painting of a cow standing in a field with a fence in the foreground and a man in the background with a dog.
