Well curing cancer once it gets loose in the body is an iffy proposition, since cancer metastasizes to other parts of the body and over time can re-emerge.

But, the FenBen cure does seem to work. I have been giving it too my dog for over a month and she seems to be doing much better. Plus they give it to dogs all the time for worms and it has zero side effects.

I would recommend the 1 gram packets to start and see how that goes.

Chaparral herbal supplements have great cancer fighting qualities as well. In your friends dogs case, I would use both. Time is not your friend ... dont hesitate to use these treatments.
