Thats a heroic story! I recently lost a dog to cancer and the loss is still very fresh. My dogs cancer was misdiagnosed and got out of hand quickly spreading to vital organs. We have no confidence in chemo therapy and were unaware of alternative treatments. We did go to NCSU's vet school with him and there was little they could do. It was miserable to watch him whittle away, even harder to make the decision to put him down.
It sounds like you have found a miracle indeed!
