"Down here in the Ozarks, asking whether a fat dog farts is the equivalent of enquiring if the Pope is Catholic or if a pig's butt is made of pork. The answer, of course, is yes; fat dogs fart. So do skinny dogs, old dogs, young dogs, and especially, gun dogs. This often is directly related to an appetite for carrion and cow pies, but I've know some dogs who could manufacture an endless supply of noxious gas on a diet of cornflakes."
