I'm sorry to hear about Bailey's diagnosis and the heartache you're going through. I lost my fifth GSD and possibly my best friend ever to lymphoma in December of 2011. River was 9 years old when he was diagnosed the April before. I studied everything I could find at the time. Unfortunately, the best survival time I could hope for was about 1 1/2 years and on average about half that time. I can only tell you that there are exceptions to that, so don't give up hope. My prime concern was for River's quality of life and I originally was not going to do chemo because of the side effects. However, we have a great vet who was willing to work with us on the cost and a chemo treatment that caused River absolutely no side effects and it gave us 9 months of great time together. He had a series of 3 shots, 3 weeks apart and the cost was about $900. We also kept him on prednisone the entire time to keep him comfortable. On that regime, River was only sick for one day before we sent him to join the others at the bridge. I will have to go back and look for the name of the drug and I'll be glad to do that if you send me a pm. In the meantime, my new best friend, Cas and I wish you and Bailey the best of luck and we'll keep you in our thoughts and prayers.
