The Duchess of York’s Spaniel Henry Bernard Chalon (1770-1849)

The picture has something of this: dog, canine, mammal, animal, pet, cute, puppy, spaniel, people, domestic, portrait, breed, sit, whelp, looking, funny, loyalty, two.
Perhaps it’s a painting of a black and white dog sitting on top of a grass covered field next to a white and gray dog with a blue sky in the background.
