I am SO glad to hear you got Kuma in right away, got diagnosed, and are treating him. I hope he makes a full recovery, and has good health from here on.
One thing you will find about YorkieTalk, is that we are passionate about our doggies, and we care deeply about each others too. I had a hard time sleeping last night worrying about your little Kuma, and prayed you'd get him in quickly. So when I woke this morning to see your update I was so relieved.
Being tiny and young, adds a little extra responsibility to you, but it looks like you are on it, and know the importance of seeing a vet quickly when things start going wrong. Too often people wait and watch, and can lose their little ones.
We'll look forward to hearing more about him, and watching him grow up
