Hound Hunters (1947)
George and Junior decide to get a legitimate job as dog catchers. The problem is that Junior is afraid of even the tiny (and surprisingly fierce) dogs. George tries dressing as a female dog to lure the dog to the truck; when that fails, he tries dressing both him and Junior in a giant cat suit. Then Junior tries a mouse trap baited with a hamburger from George's lunch and catches George ("a bad thing"). Finally, they dress as fireplugs and get far too much attention.
