Bella and the Big Bad Bully

It doesn't matter how big or small you may be, anyone can save the day and be a superhero.
Bella, a small, spunky Chihuahua, feels as if she can't do as much as the rest of her pals because of her size.
Her pals always made her feel accepted - that is, until the town bully comes by.
Ty, a bulldog who is much larger than the rest and wears a shiny chain around his neck, stirs up trouble with Bella and her pals.
It isn't until Ty and the rest of the gang is in trouble and desperately need Bella's help that he realizes he shouldn't bully others because of their size or shape.
