My dog Lenard has been so much more active because of your product. My Pug has been blind his entire life and because of that he has been more sedative in his old age and has put on a few extra pounds. We brought him from my parents house to my house so I could put him on a strict diet and exercise regiment. I noticed that he has been favoring his back leg, so I found your product and have been using it every day for the past month. We went from wondering how his quality of life was hobbling around to him running around and playing with our 1.5 year old puppy!!!
