First of all I am so sorry about your little girl Faith. I know exactly what you are going through. My boxer, Butch, was five years old when we found out he had lymphoma. It was also in his liver and spleen. Our vet sent us to a oncology vet and she said that we could do chemo, but that he would probably only live about 1 more year and it was very hard on the dog. We opted not to do that so we gave him predisone twice a day and feed him a special cancer diet that she gave us. She didn't think that he would make it past 2 months, but he lasted almost 8 months. I was pregnant at the time so everything was so much worse for me. He was our very first boxer and it was hard on our whole family. I wish you the best with Faith and I will pray for you. Please cherish every moment and spoil her like crazy as I know you will. Hugs for you both from my whole family!
