Our retired racer, Puma, has always been a very happy and healthy greyhound. Recently, while walking down some stairs, she froze up and yelped. After carrying her down the stairs, it became noticeable that she was limping pretty severely. Luckily we had pain meds on hand. We took good care of her with pain meds and a heating pad, and although the limp definitely improved, we ended up taking her to the vet about a week later just to be safe. On Friday, after taking X-Rays, our vet informed us that Puma has Osteosarcoma in her right front shoulder. Fortunately, we did catch it quickly and there are no signs of tumor or spreading to the chest or lungs. Despite getting a diagnosis early on the game, our vet informed us that this cancer spreads rapidly and that her life expectancy is probably only three to five more months unless we choose to amputate the leg and begin chemo. We are having a very difficult time deciding whether to just accept the cancer, begin palliative care and keep her on four legs until it is time to euthanize in a month or two. Or do we go forward with the amputation and chemo in the hope that is extends her life for another year +. Any advice, recommendations or assistance would be greatly appreciated.
