'Bluey' was originally based on another character: 'It was going to be about him,' creator said

(NEXSTAR) – There isn’t really a canine character on “Bluey” that can’t sustain their own standalone episode — and many often do. Over the course of the show’s three seasons, plenty of secondary and ancillary characters have been given their moments to shine, with some storylines focusing on one of Bluey’s friends or neighbors, rather than herself or her family.

But if "Bluey" creator Joe Brumm had followed through with his original plan, one of those supporting characters would have been the lead of the whole series.
