I'm so sorry no one has replied to this - sometimes around the holidays we get scarce here.
I'm also very sorry to hear about your precious new baby. Sadly, liver shunt runs in yorkies and we've had so many members here have to face what you're facing.
I can't give great advice in this area since I haven't been through it, but I know others will share their knowledge and offer support.
I'm going to move your thread to the "SICK / EMERG" section so it gets the proper attention.
I'll be keeping you in my thoughts and looking for updates. Hang in there
