S1 E1 Meet the Chapmans
In the premiere episode, Dog defends his family name as he chases down a ""Chapman gone awry."" Floyd Chapman is a bail jumper with the same last name as Dog (but no relation). Dog uses a phone ruse to get information from Floyd's mother, then rocks his team into a state of aggressive anticipation to make the bust at Floyd's family home. - Summary from A&E's ""Dog"" website
