here is my response to pm
let her rest she is a big yorkie she can go without eating for 5-7 days so do not feed her let her tummy rest - sounds like could be pancreatitis - ulcer is when they throw up coffee grounds looking stuff in the vomit and this is blood. See how she does for next 8 hrs and let her rest NO FOOD. Offer her water off your fingers or take an ice cube and let her lick it - she does not need honey she is not going to go hypoglycemic at that size so do not do that. Just make sure she has some fresh water but she can go 12 hrs with no water as well.
how much does she weigh? I would withold food for 12 hrs let her tummy rest and let her drink water if she gulps water and vomits i would hold water up and give to her in small amounts holding bowl but do not let her gulp and vomit then gulp and vomit you need to stop the vomitting which it sounds like you did. AFter 12 hrs giver her tiny amounts of food at a time every couple hours if she will eat if she will not eat then let her be do not syringe food as she will eat when her tummy feels better - sorry she is sick
