[Amazing Yorkies]

I have had that experience, and she is likely pregnant. This is probably morning sickness, and will pass. However, you might need to be giving her Nutri-Cal, and try Yogurt, Chicken babyfood.. something that she will eat. Yellow bile means she has nothing in her stomach, and needs to eat or she might go down. You might even need to put some in a syringe (without needle, lol) and force soft food. Your Vet might also decide to give her a Vitamin B shot for appetite. She will probably get a huge appetite after this goes away. But you may have to spoil her just a bit to keep her eating. Just keep an eye on her and don't let her go down. Loss of appetite shouldn't last too long, but the lazyness and not the regular self may last the whole pregnacy.
