Glad to hear Ben is doing so well. Thankyou for posting his story. I am sure if we can get a few stories on this forum it might well help others to at least consider it. Most dogs I have read about seem to do well.
I can well relate to how you felt when told it was cancer. After 4.5 years I know precisely what I was doing when I got the call from the primary care vet (who had told me it wasn't cancer and they got it all) and the shock and disbelief I was in. I could give a detailed account even now of everything that happened over the next five days after that call. Wonder if Dr Ken's recollection is as good as mine when he had to call a panicked owner who was having visions of a weekend upon us and we are doing nothing whilst cancer is taking over Frodo
Hopefully in the future we might get more answers to osteosarcoma so more dogs get better treatments and cures. If you have any videos or pics of Ben please feel free to post them. I will shift this to the amputation forum so people specifically looking for that will see it quickly.
