Quick Rocky update. I moved his appointment with the oncologist up a week since I was pretty sure his tumors were growing again, and I also felt a new one on his left side.

Unfortunately, I was right. All three of the tumors on his right side have grown and he does indeed have a new, smallish one on his left side. So the Palladia seemed to work for about a month and then the stupid cancer found an answer for it these last couple of weeks. So we're done with the Palladia. 

The good news is the cancer, so far, has stayed away from his lungs/vital organs. They're in his skin and muscles. And, so far, they're not causing him any pain/problems. 

So after the Carboplatin and now the Palladia have stopped working, we're on to Plan C. He got an injection of Mitoxantrone at the office today, and his oncologist sent us home with Chlorambucil (Leukeran). The plan, for now, is for him to get the Mitoxantrone every three weeks and I'll give him the Leukeran daily. I don't know much about either of these. Does anybody here have any experience with either one of them?

The oncologist said the Mitoxantrone is similar to Doxorubicin, but not quite as potent. But it also doesn't affect the heart like the Doxo can, and since Rocky has had heartworm, the Doxorubicin is out for him. 

It feels like we're in desperation mode now, just trying anything before the clock runs out. But Rocky still seems happy, so we'll keep fighting.
