The image of Mrs. Thompson that appears in the daybooks is a variation of the pose that appears here. Rather than holding up the skirt of her riding habit, she has both hands folded on the corner of the back of the chair. The dog, however, has not moved an inch and its head is at exactly the same angle, which raises the possibility that the animal is actually a stuffed prop. In fact, the animal appears in at least fifteen other unconnected portraits around this date, and in every single one of them it looks exactly the same. Sometimes it's on a chair, and sometimes it's on the floor, but the angle of its head and the positioning of its body never change.
