I'm so sorry. He looks like a great dog.
I can't really answer your question, but I do agree with the prednisone vs. the chemo. I'd treat my 3 year old dog with chemo, but an 11 year old I wouldn't. There just isn't enough benefit there, for me, to justify the stress to the dog. Others may feel differently.
As to how he's acting . . . Muggsy (in my sig) died 2 weeks after his 13th birthday of liver cancer. I had no idea he had it. He was a little slower and eating a bit less, but he was 13. Otherwise, he acted exactly the same. Friday night, he danced and spun as I tried to get his leash on him for our last walk of the day. Saturday morning, he couldn't stand. Dogs don't show symptoms like people do. The good thing about this is that Scooter might be his happy self for the remainder of his life.
