We have a 13 yr old female Great Pyr. She also was recently diagnosed with an osteosarcoma on one of her transverse process’. No way to remove that. We have no idea what caused it, but 13 is quite old for a dog as large as she is at close to 100 pounds. We are on a well, so she has never had water with flouride. I do believe in the bodies ability to heal and have removed everything that could potentially be toxic that I can identify to either slow the growth of it, assuming that is possible.
I wish you well with your greyhound.
