Our black lab was diagnosed at age 10 with two types of cancer in October 2007 and given 3-4 months to live if she had major surgery. We opted to try to keep her comfortable instead. A friend knew of the Casey pet supplement which was in it's final testing stages before being sold to the general public. We were able to mix her food with it twice a day and she loved it. We had her skin cancer removed and it did not return as they often do. Although our dog died a few weeks ago, she survived 16 months with bone cancer and had a good quality of life up until the end, still playful and going for walks.I feel this product was a factor in allowing her to live longer and better and for that we are eternally grateful.
