Bests & Worsts Reviews from Amazon

I bought this figuring that it was worth taking a chance but didn't expect to notice a difference but the results are obvious. I have a 15 year old Wheaton terrior who was having a really hard time making it down the stairs to go outside. She was not getting up in the morning to go like she had always done. She is still hesitant some days but most of the time she goes outside with almost no hesitation. A few times she has almost pranced. I was wondering if I had much more time with her and I want her to have a good quality of life but I was scared. I don't know how much time I have with her but I have no regrets buying this and we are on her third bottle.
