What is the name of the talking dog who appears in The Powerpuff Girls?

The Talking Dog is the name used for the talking canine character in The Powerpuff Girls.

The character appears as a dog capable of human speech, making him one of the show’s deliberately absurd supporting figures. The series often gives ordinary animals, household objects, and minor Townsville residents unexpected roles in its fast-moving comedy.

The Talking Dog should not be confused with the girls’ stuffed octopus, Octi, or with other animal characters that appear in individual episodes. Those characters have separate identities and functions within the series.

Character names in The Powerpuff Girls can vary between dialogue, credits, merchandise, and reference lists. For that reason, this answer uses the straightforward name recorded in character references rather than assigning the dog a more elaborate invented name.
