No, Doug explicitly does not have Trained By A Master. It's mentioned early in DW5, in fact, that he has trained himself in hand-to-hand combat by copying the moves of people he's fought and making a patchwork crazyquilt style of his own out of them. He's never had any kind of formal combat training, at least not until he started on the Walk -- and that training is almost exclusively in melee weapons.
