Huckleberry is an anthropomorphic blue dog that speaks with a deep Southern drawl and has a cheerful, relaxed personality. He mainly wears a small zig-zag straw boater hat with a polka-dot band, or occasionally a black top hat, and a red bow tie.

His shorts are usually in one of two formats. In some episodes, he tries to perform jobs in different fields, ranging from policeman to dogcatcher, with results that backfire, yet he usually comes out on top, either through slow persistence or sheer luck. Huck didn't seem to exist in one specific time period as he has also been a Cowboy, a Roman gladiator, a Medieval knight, and a rocket scientist. He lives in the city of Hill Street Neighborhood, known as the city of music, which is known for the most famous store in the world, Maple Mall. He's also known for chasing the ice cream truck, whenever he sees, or hears it.
