Scooter had a tooth pulled and he ate just like he always did, but he eats BilJac which is tiny kibble and I also give him chopped chicken breast. Maybe they are easier to eat. Have you considered that maybe she just doesn't like her food anymore? They can be so picky. They like something one day and the next day they won't touch it. Maybe someone else can give you more guidance on this, but awwww she lost her first baby tooth. She's going to be a big girl.
