My vet told me it was common in Yorkies to have weaker stomachs than most dogs. Maybe he told us this since Cookie gets sick easily. We're trying to learn the limit for her on treats and such. If we give her too much, she pukes. She also pukes everytime we give her red-colored treats. I don't know why but she does. It seems that even though everyone here says Yorkies shouldn't have weak stomachs, there are quite a few Yorkies here that do have problems.
