Really makes a difference!

I have a 10yr old Dachshund who sometimes has back issues which the breed is prone to. I've tried other products but he seems to tolerate the taste of this one best but I still have to mix it in his food, he won't eat it on it's own. I know this product works because I ran out once and after a week or so he was having issues climbing up the stairs. I ordered more and after 4 or 5 days of taking the product he was back to normal.
