Barnaby Joyce threatens to walk out of 7.30 interview after host tells him to ignore his barking dog

Former deputy PM Barnaby Joyce — now sitting with One Nation — warned 7.30 host Sarah Ferguson during a live cross on July 20: "Don't be rude. Otherwise, this interview will come to a grinding halt." Ferguson had told him to stop fussing over his barking dog and answer the question. The clip went viral.
