Bugs Bunny lectures about dogs, but first must struggle with a projectionist who, when Bugs says that the lecture is about man's best friend, shows a picture of a tarantula and then a Whistler's Mother portrait, presumably because, "A man's best friend is his mother." When Bugs clearly states that he intends to talk about dogs, the projectionist flashes a picture of a wiener (a hot dog). "The domestic dog," retorts Bugs, and a picture of a wiener in an apron instantly appears. Finally, the projectionist does something right, and Bugs' requested pictures of dogs are shown: the sheep dog, as seen in a cartoon defending a flock of sheep from lambchop-desirer Ralph Wolf and Ralph's smoke bomb, rock disguise, and underwater unicycle; and the bulldog, willing in one cartoon to resort to any deception to attain meat and acting in another cartoon as protector of his scrappy baby son against a conniving Sylvester.
