So why this particular brand? Is there anything in particular about this one? I want to try it on a dog. My rotti is 13 and has a lump on him. His bro died last month. (cancer) The vet said he tests negative for cancer, but just the same, I wish to see if it contains the fatty tumor on him. It might improve his life, and hold off any cancer cells.
