By Leaps and Hounds(1951)

Herbert, a hound who has never seen a fox, joins the Foxhound Academy to get his foxhound credentials. The instructors describes a fox, and tells Herbert to remain at the back of the pack during the hunt and blow a bugle if he sees a fox. The lead dogs pass by a fox but not Herbert, but the fox takes Herbert over to a sleeping bear and identifies the bear as a fox. Herbert blows his bugle, but the hunt resume, without Herbert, when the dogs see the bear. The fox returns and, at Herbert's invitation, joins him for a spot of tea.
