Thanks so much for the great info and so glad that Sawyer is feeling better and now you know and we know how to fix this. I worry too since Izzy is a picky eater and tiny to boot. I try to give her some Yorkie Yummies before bedtime but sometimes I forget. Then she doesn't eat much in the mornings either - maybe a morsel or two but at least something in her tummy. She has never vomited but she will get lethargic if she doesn't eat something in the morning.
