L’Amazzone con Cagnolino al Seguito Giovanni Boldini (1842-1931)

The picture has something of this: cavalry, seated, mammal, horse, people, equestrian, cowman, rider, recreation, wear, saddle, competition, man, action energy, lid, two, bridle, fast.
Perhaps it’s a painting of a man in a top hat riding a horse with a dog on the ground in front of him and a dog in the background.
