The best known of all G related Disney has to be Goofy.
Goofy was originally known as Dippy Dawg. So, if you wonder, indeed what sort of animal is Goofy? He's canine. Look at those teeth after all. I personally love Goofy. Check out Goofy's Kitchen, next time you are in Disneyland's neighborhood. Great place for a great character meal. Lots of good food and character intervention. Call ahead for advance reservations.
So what is your favorite G?
