For some of mine, I used Scribus for the layout / dialogue.

i have a comic strip at https://bimshwel.com/ope but whether it is "furry" is arguable.

In terms of making a comic, I've been working on an epic since Jan 95, but I've been too poor to start production on it, but it would work as a comic as it was made to be visual. Other then that, there's this: https://furplanet.com/shop/

There used to be one long ago that had the ol Domino furry super hero comic, but I think that website was taken down.

Shantae Howard's "Extinctioners" is essentially furry superheroes - with a VERY strong flavoring of X-Men running through it.

Weeeeeeell if you're looking to read one, I've got one :3

This Title card is the start of the proper chapter, though there's a short prologue if you click "first", albeit the prologue kicks off with nsfw right away, lol.

SoFurry also tends to be good for stories and to some degree comics.
