- A full face mask resembling a wrinkled bulldog was originally constructed for the character of Barf, but Mel Brooks quipped that 'if they were going to hide John Candy behind a mask, he might as well hire someone else for half the price'.

They finally settled on animatronic ears connected to a hairpiece, a small nose application and a patch over one eye just like the dog from the [Our Gang] shorts. The costume was operated by three people. John Candy operated Barf's tail using a hidden control in his paw, while two assistants each controlled an ear.
