The character first appeared, nameless, in Avery's 1943 cartoon Dumb-hounded. Though he would not be called "Droopy" onscreen until his fifth cartoon, Señor Droopy (1949), the character was officially first labeled Happy Hound, a name used in the character's appearances in Our Gang Comics. After the demise of the Droopy series in 1958, the character has been revived several times for new productions, often television shows also featuring MGM's other famous cartoon stars, Tom and Jerry.
