Of the two Mastroianni brothers who work on "Dogs of C-Kennel," Mason was the one who first set out to be an artist. His early education took place at the Rhode Island School of Design and the DAVE School in Orlando. Before joining up with his brother on their current comic strip, he came away with an Emmy award for computer graphic animation for his work at Wet Cement Productions. His brother Mick studied to be a stuntman and precision driver before joining up with brother Mason to work on the comic strip "B.C." as a writer after the death of Johnny Hart. Now, in addition to collaboration on "Dogs of C-Kennel," the brothers both continue to contribute to both "B.C." and "Wizard of Id."
