Rebel (Lana in the PAL version) is a longhair female Chihuahua often seen in Pro Competitions, owned by Jacob. She has a seemingly shy personality, usually being scared of other dogs. She wears a Hibiscus Flower. Your dog can befriend her very easily if it is the eldest/the first puppy you got. Sometimes, if your puppy is being jumpy, you can pull on their leash and they might make friends with her.
This inquisitive little female is as sharp as a tack.
