its an individual thing. most larger intact females will tolerate it, some dont like it, and some love it to the point of preferring anal over vaginal most of the time.
anatomically its easy to see that an intact bitch will feel pleasure from the rectal wall putting pressure on the vaginal floor and vaginal sphincter even if the particular individual doesn't take pleasure from the anal/rectal stimulation itself though some bitches certainly do, to the point of demonstrating it by rubbing their anus against you more than their vulva.
