The most known hero of Tex Avery is Droopy, which appears for the first time in Dumb-Hounded , in March 1943. Until 1955 it will be used 16 times. This longevity will have a significant influence on the behaviour and the layout of the character, who was not yet well defined for its first use. Droopy has been inspired to Avery by a character voice in a radio broadcast.

In the no track race which represents Dumb-Hounded, Droopy is a sad and lymphatic dog which always succeeds in preceding the escaped wolf, everywhere this one hides. But it still walks on its four legs and makes its needs behind a terminal for fire while reddening. Yet, its calms in front of the wolf frenzy will be a constant of its character throughout its career.

However, it is rather the development of the wolf, then at the first rank of the averyan characters. It is necessary to wait two years before seeing it reappearing in The Shooting of Dan McGoo (March 1945), always in front of the wolf. The character, much more precise, is on the point of settling in the universe of Texan. The " Hello, happy taxpayers " resounds a little like the " What' S up, Doc.? " of Bugs Bunny.

It is now Droopy-McGoo who must ruin the bringing together in love Girl-Wolf such as it had been defined a few months earlier in Red-Hot Riding Hood.

The Wolf-Droopy tandem functions so that it is strike back, 8 months later, in Wild and Wolfy. If the wolf escapes all its prosecutors, it cannot be demolished of Droopy, true tinea fixed on its heels. Always also phlegmatic, the sad dog - in a more simplified graphism - became this hero that nothing could reach. We find it again in 1946 in Northwest Hounded Police which develops, like Dumb-Hounded, the topic of the not track race. Then, Droopy passes to the trap door during two years and half.
