Oh Liz, I just found this post. Sometimes I don't go to the Dog Health area because I am afraid I will find threads like this one.
I just want to cry and cry.

Buddy, please get well. I know you are trying so hard for your Mama. It is so upsetting to know that you are hurting yet again. All of us love the Buddy Boy so much. We really, really do.

Liz, I know whatever decisions you make for Buddy will be the right ones because there just is no one who could care more for an animal than you do. You do the best you can for Buddy. That is all anyone can ask.
