Hi Pat--you were lucky to get that great advice from spaniel mom--it is probably the most knowledgeable posting I have seen on this board.
I would like to also encourage you to make sure that you are seeing an oncologist for your dog. Bladder cancer, should that really be the diagnosis, is a tough battle--you don't want to waste time with the wrong treatments.
I'd also like to give you some words of encouragement--my Annie was diagnosed in February of 2005--that's over three years ago. At the time of her diagnosis, the median survival rate for dogs with TCC was 180 days. I have only treated her with piroxicam during this time. My oncologist did not think that surgery was an option for Annie and he also did not think that her cancer would respond well to chemo. We have been lucky so far. Annie's getting older and the past few weeks have not been great for her, but she's still happy and eating like a horse. We'll be going in next week for a check up and I doubt that anything will change with her treatment.
Good luck to you, I know it's hard, but try to not worry. I promise you that it does not help a bit.
Marty
