This is Muttley, the sidekick of the villainous Dick Dastardly. Created by Hanna Barbera, it made its first appearance in 1968, in the television series Wacky Races. Recognizable by its mischievous laugh, this dog whose breed is unknown is a Machiavellian being.
It can also be found in Dastardly and Muttley in Their Flying Machines and in other productions by its creators, notably in Scoob!
Find him in a 1000% Bearbrick version, with a smile that says a lot about his little person !
