My 7 year old female Golden Retriever was diagnosed with lyphmnoma carcinoma and it's quite bad and in her bone marrow also. We've brought her to the Oncologist at the New England Oncology in Waltham, MA and she has completed her 3rd weekly chemo. But, he wants me to give her Heartguard and I think that the chemicals going into her body are invasive enough. I've also been giving her raw organic meat, like chicken and the livers, vegetables and vitamins from a canine nutritionist. Now, Dr. Jeff, I need your help; one says to not give the Heartguard and the Doctor says I should. What do I do? Thanks for your help.
