The decisions we make for the health care of our babies, more so on the advice of a professional, is always done with their best interest in mind. I know you followed that vets guidance based on his education and profession because you loved Zeus and wanted to heal/make him feel better. They all have some difference of opinions on treatments. Prednisone 10mg once a day or Prednisone 5mg two times daily is separating apples from apples.
I think its wonderful your spreading the love you have to another baby and two Yorkies are always better than one
Yes, let these babies lick your tears of grief away. You sound like such a loving, caring person and what lucky babies to have you love them. Good luck, and please keep us posted here at YT!
