This is Rory and Duke. Rory is 9 years old and suffers from separation anxiety, the past couple of years I have noticed her legs getting a little weaker. Duke is almost 5 years old and had acl surgery 2 years ago. The only thing that has helped both of my pups has been the max cbd treats. I give them some almost daily and they RARELY limp if at all! Rorys anxiety is so much better and we are all so happy. I am so thankful to have found this product
