What diet should I feed my dog with cancer?

marleyfu asked:


He has had surgery for hemangiosarcoma, and I want to prolong the life he has left.

I’ve just switched him to a raw diet combined with all protein and vegetable kibble. No grains.
Yes, I have talked with the vet and he suggested a few different diets. I am looking for peoples’ experiences.
I”m also giving him 1000 mg of Omega 3 a day.
