Ace Hart

Ace Hart (voiced by Ron White) is the star of the animated segments on Dog City. Referred to as "Ace Hart, Private Eye Dog," he's ostensibly the creation of animator Eliot Shag, but exchanges wisecracks, advice, and arguments with Eliot on an equal level. However, Ace is also subject to Eliot's whims, taking his revenge with his paintbrush and often leaving ace with nor esort but a plaintive, pleading cry of "Eliot!" Within the animated Dog City, Ace's allies include Eddie and police chief Rosie O'Gravy, while his chief adversaries are Bugsy Vile and his gang, and the fiendish Baron Rotweiler.

Ace Hart served in many ways as the idealized animated alter-ego of Eliot, and appeared in puppet form in the episode "Gotta Have Hart." The puppet, and the basic character, were revised versions of Ace Yu from the original Dog City pilot.
