Yes - unfortunately he did have radiation. I had a choice to use an oncology clinic that was over an hour drive from my home that he would have to go 3 times per week for 6 weeks and lots of money. This would have been the gentler form of radiation treatment. Instead, because of time & money, we chose a more aggressive form at Michigan State University's Veterinary School, once every 3 weeks for 4 treatments. I would never do it again in an especially old dog. But, I did love him and took a chance he'd do well. (The cure was worse than the disease.) It was costly, less overall than the 1st option. It did him in, because as I mentioned, the loss of tissue in conjunction with radiation - more tissue loss. He never recovered. I still feel terrible for the outcome. At the time, we had no way to know what would happen. The vet at MSU should have given me better advice, considering his age and the effects of the radiation. I was just optimistic and hopeful.
Did the vet suggest doing radiation? If so, please-please go the gentler, costlier and long term option. She is young and likely far less damage to her tissue will result. My suggestion is from the phrase "If I knew then what I know now, I'd do it better."
Please keep me posted - Lots of hugs and prayers for you both.
