 In the film "Barnyard", showing anthropomorphized cattle of both sexes walking on two legs, instead of either showing genitals of male cattle or not showing them, the concept of a "male cow" was used, with an udder.In "Underdog" a partly animated anthropomorphized dog is shown with a penis when a real dog is filmed, and without one in the animated parts.Paintings are sometimes changed because of changed modesty standards, and later sometimes changed back.
