Roscoe's fight for cancer

I'm Roscoe's dad. I don't know where to start. He's 2 and has a life to live. I'd like to give him the best life he can. The cancer he has is treatable and apparently is very successful. And if I can get a year of happiness to him, I will. Please help me save our family pet. He's our family. Any contributions will greatly help and make the world of difference.
