The Boyingtons trademarked the Pronto Pup name in 1942, and began selling franchises of the carnival treat. Their company, later called The Pronto Pup Company headquartered in [[Portland, Oregon]], would ship the franchisees the proprietary flour mix, but the rest was up to the business owners. There was only one rule: Pronto Pups could only be served plain or with mustard, but no ketchup. However, this rule was relaxed several decades later.

Following World War II, servicemen who had sampled and helped build the immense popularity of Pronto Pups while stationed throughout the Western states, realized the possibilities in Pronto Pup shops for their own post-war business. Franchises sprung up from coast to coast and Pronto Pups become a national sensation.

Very few of these original Pronto Pup franchise restaurants exist today, but Pronto Pups can still be found at many carnivals and county fairs courtesy of franchise street vendors.
