As you can see my dog has a deformity from birth. He would always lick and chew at his paws. One day I brought him to work with me took a X-ray and revealed he had a bone missing. Which would explain licking is pain related mostly, I started it him on it. It’s very inexpensive I order right off their website. Within a week I noticed less licking less lag in getting up, and more energy. I highly recommend this product
