Oh! I've been wanting to ask this same question. It's hard to find animal comics on most comic sites. Also a huge fan of dinosaurs, and in the process of planning a super short comic centered around them, so will def sub!
Anyway, I've got a dog comic that focuses around an animal ~ youkai cast (with youkai thus far also being all animal forms rather than human.) The story follows a young dog trying to find some wholesome adventures, only to be derailed by a strangely-familiar apparition.
(omg just clicked and the artistic backgrounds of the prologue alone are amazing)
