I have the k9 belly bliss, which makes their coats soft and shinny, plus all of them range from 5 y. to 18 y. They all act like puppies again. I also have dog immune support. One had a spot on his leg, could not get rid of it, until this, and another had big lumps coming up that no medicine could get rid of. The leg spot is gone and healthy looking again, the lumps are almost gone, it's only been two weeks, so happy I got this
