After just 1 week of using this I have noticed a massive difference in my dog. She is 16 yrs old and has arthritis in her lower spine and was struggling with getting up and down and moving around but after 1 week she is already running around and playing with her toys and back to her mischief that she would get up to 10+yrs ago. She is acting like a pup not a senior doggie. Thank you for such an amazing product we love it and have been recommending it to all our friends and on my fb page.
