Bird-Brain Bird Dog is a 1954 animated short film, directed by Dick Lundy for MGM as part of Metro-Goldwyn-Mayer's Barney Bear series, involving Barney getting himself an uncooperative dog to hunt birds.
Barney chases the bird and hides behind a tree, to which the dog sneaks up behind him and draws the quail on his trouser seat.
The dog shows it to Barney and, thinking it is the real bird, shoots himself in the rear.
Barney attempts to run home with the bird, but is tripped again by the dog and his gun is broken in half.
The chase continues until Barney has the dog and bird cornered in a bush and fires at them.
