Children and a cow = 1635-39, 44x54, Metropolitan New York Aelbert Cuyp (1620-1691)

The picture has something of this: mammal, cattle, livestock, cow, farm, bull, agriculture, animal, calf, people, two, cavalry, horn, group, pasture, milk, beef cattle, herd.
Perhaps it’s a painting of a cow, two children and a dog in a field with a dog on a leash and a boy holding a stick.
