The type of animal that sunspot is on Ready Jet Go is a dog.
Sunspot the dog on Ready Jet Go is one of my favorite characters on that show.
He's awesome and funny and he's one of the main reasons I watch that show because of him being so funny.
Without Sunspot on Ready Jet Go I would say the show would not be as good.
But heck it still might be but Sunspot on ready jet go really does a lot to make that show funny and really worth watching.
