Just wanted to post an update. My official decision has been made: no chemo. We saw Onco #2 on Tuesday and she was great - gave us all the info (most of which I already knew) but before we even went into see her, I knew this wasn't the route for us. Just sitting in the waiting room is stressful. The owners are sad and worried and stressed, many of the dogs are stressed. There is just a blanket of hopelessness and sadness in the air at both oncology centers we visited. That's not what I want for our remaining days - however long they may be. 

I will post updates on Chance's progress. We have a wonderful Holistic vet and are meeting with SFRAW feeders on Monday to see about any additional diet changes he may benefit from. Thanks to everyone who chimed in with their thoughts on the matter. It was helpful to read, and to just be able to spew out some of my thoughts here to help me think everything over and come to the final decision.
