RiggoD,
I posted in the other thread (about the dox. treatment), and just wanted to add a little more here... I'm so sorry. I KNOW what you are feeling, believe me.... Has your vet done the MOPP protocol for Riggo?? It stands for Mustargen, forget what the O is (but whatever it is Abby didn't do it as that's what she was on in her first protocol and it failed), Procarbazine and Prednisone. That was her "rescue protocol" and it lasted about 5 weeks.
If I could offer any advice, it would be to enjoy Riggo as much as you can!!! Be strong for him! Don't let him see you upset, even though your heart literally feels like it is breaking. As for myself, I would cry every day to and from work, and even at work, but I made myself be strong in Abby's presence. Our special babies can sense how upset we are.... and why make them feel worse?
I hope that you get some good news at the vet. No matter what you are feeling, know that others have been there and we are here for you. It's going to be ok... God never gives you more than you can handle. Remember that.
