Obama hits Romney for putting a dog on the roof of his car.
Update: Obama reading his book's passage about eating a dog.
Update 2. Romney spokesman Ryan Williams says on Obama's dog attack in a statement: "After sanctimoniously complaining about making a "big election about small things" President Obama continues to embarrass himself and diminish his office with his unpresidential behavior. This election is about creating jobs, turning around our economy and helping the middle class. The President's policies have failed on all counts and he will do anything to distract from his abysmal record."
