We are following the protocol in Dr. Eisen's book, Dog Cancer: The Holistic Answer. This includes liquid zeolite, AveUltra, AHCC, enzymes (I'm using a powder rather than pills), probiotics, and a multi vitamin without vitamin C (vitamin C would cancel out AveUltra). For grain-free food, we use Honest Kitchen's "Preference" plus chicken breast that I cook in the crock pot a couple times per week. I've also consulted with a negentropy health practitioner who makes liquid silver to help boost the immune system. He also told me about the importance of "grounding" - being in physical contact with the Earth for extended periods of time to benefit from its emmission of negatively charged electrons, which facilitates healing and counteracts exposure to free radicals. So we try to spend a lot of time outdoors when it's not raining. Apparently rain makes Dobermans melt.
