I'm saying a prayer for Doc. We lost our beloved black lab Jake four weeks ago today to lymphoma. I did some internet research and found that chemo is very tough on dogs, and it usually only buys 6 months to a year. Jake was diagnosed on 12/31, and he probably could not have handled chemo anyway, even though he never showed any signs of illness until right before Christmas (we thought it was a cold, put him on antibiotics, then took him back to the vet when the lymph nodes swelled again). We put him on prednisone and saw an immediate improvement in how he felt - his appetite came back, etc. We had him put down because he began to suffer, and we did not want the inevitable to occur with pain. Please consider prednisone - it was a great help to him. I'm sorry, and I wish you all good luck.
