Of course, by now...you know that dogs do indeed pass gas. Finn farts and burps all the time. When he burps, his jowls puff out. It's pretty funny. Dudley is the funniest farter, though. He will jump up, get into a really aggressive stance and growl. He gets so angry when he does, it's so funny. He will jump up and stare at his rear end and growl every time. I don't know that I've ever heard Freckles fart. I imagine if she does, she goes outside to do it. She's really ladylike.
