I second what LuvMyYorkies says above.

I'd definitely get NutriCal, which is available at PetsMart, PetCo etcetera. You can use it more than twice a day if she is not staying level.

Also, make sure you give her some before bedtime...also give her some kind of protein before bed too. Give her some nutrical right when she wakes up in the morning too, as her blood sugar will likely be low after not eating all night.

Are there certain times of day when she is crashing? Is her appetite okay? Is she acting weird after eating or anything?
