This slip up is from the episode "Miley Get Your Gum". In the very beginning when Oliver sticks his hand in the limo's window hoping Hannah Montana kisses him, a little dog kisses him instead. The dog is in the limo with Lilly, Miley (Hannah Montana), and Miley's dad. They clearly make it seem like it is the Stewart's dog the way they talk about and you figure it is. Except one thing, the dog is never seen again! I have seen all of the episodes of Hannah Montana and the dog was never on it again. Plus in the episode where Aunt Dolly visits, Miley says "we are thinking of getting a dog". Hello guys, do you have a dog or not?
