My dog began having hip issues at a young age and after consulting with a vet, I was told that she had hip dysplasia and it was common for her breed, Pit Bull/Lab mix. With surgery, I was looking at thousands of dollars and no guarantees. I happened to come to work and speak to a co-worker about the issue and his father is a vet. He recommended KnuBar. I have to tell you that within a week or two, my dog stopped limping, she was jumping around and has been for the last 5 years. She receives one supplement per day and she has not had a re-occurring issue. I cannot say enough great things about KnuBar!! Oh, and she really likes them! It saved my dog and I don’t have to see my dog suffer. Thank you KnuBar, I don’t know how you do it and I don’t care, I am just so grateful!
