If your fur baby is real small she should not go all day w/out eating. Let her free feed on dry kibble all day and maybe offer her healthy treats a couple times a day. Maybe some plain non-fat yogurt, cottage cheese, shredded carrots, etc. Just small amounts though.
It's important she receives enough nutrients. Maybe on your next vet visit you could discuss the best diet plan for her. Alot has to do with her size/weight/eating habits etc. A meal plan for one Yorkie isn't always the best for another Yorkie. Each is an individual with his or her own special needs.
Good luck.
