Hi there. I'm afraid I don't understand all the abbreviations in your question, so it's hard for me to make sense of what you're asking. In general, I can tell you that osteosarcoma (the most common type of bone tumor in dogs) is a very aggressive type of cancer, and most dogs do not live more than a few weeks to months after diagnosis without amputation and chemotherapy. So if your dog lived for 1.5 years after the initial diagnosis, he may have simply been very fortunate, or he may have had some other type of bone tumor, or some other problem entirely - since I didn't get to examine him and the time and have not seen his x-rays, I have no way of knowing. If your dog has now passed away and you would like to get a more definitive answer as to what was wrong, I would recommend having an autopsy done - called a necropsy in animals. Your veterinarian should be able to advise you on how to arrange this, if you wish.

Hello and thank you for reaching out about your dog. These xrays are very concerning for either a fungal infection (very much dependent on where you are living) or a bone cancer (osteosarcoma). These xrays I am sure have also been evaluated by your veterinarian and hopefully a radiologist as well. I would recommend chest xrays to look for cancer metastasis or diffuse fungal infection and you may need to have your veterinarian perform a bone core biopsy for a diagnosis. This is usually very painful and your dog should be on good pain meds and rest during this time. Treatment options are very different for bone cancer vs. fungal infection so a proper diagnosis is extremely important. Best of luck!
