I have just finished reading all of the posts.
Oh my gosh. I am so sorry your little guy is so sick.
You are doing such a wonderful job with him but I wonder if he should be in a hospital.
He is so very lucky to have you for a family. Yorkies can pull so very hard at your heartstrings.
I will keep him and your family in my prayers.
Hang in there little guy!
Please keep us posted!!
