    It does help

    By Tony on Aug 5, 2018

    I have an older border collie who has a bad anti-bacterial resistant bacterial infection in her urinary tact. NK-9 is a part of my treatment for her as , obviously anti-bacterials do not work for this. I am using this to help keep her immune system strong and I also use green tea with honey infused into the beverage which i mix with her meal and the combo seems to have knocked those nasty little bugs back into their cage and this is giving her a quality life vrs the opposite

    Great product!

    By Ellen on Sep 2, 2017

    Our dog was diagnosed with bone cancer a year and a half ago. The leg was amputated and he went through 5 or 6 weeks of chemo. We immediately put him on NK-9 to boost his immune system. Today he is alive and well with no sign of cancer, though he is 13 years old now. We plan to keep him on it the rest of his life -- however long that may be. (We're hoping to have him for another few years.) Has the NK-9 been responsible for his survival from cancer? We believe so since it has never appeared anywhere else.
