Hi and welcome to YT
! I'm so very sorry for your loss
, how tragic - and SO very young too; heartbreaking for you.
As for Tasey -- you said 1/4c + 1 tablespoon of wet food "at a time" (twice a day, I think?) - that's a LOT of food actually, for most yorkies. Unless you have a really large yorkie maybe...? Did your Vet provide you an "ideal weight" for Tasey?
