Bests & Worsts Reviews from Amazon

I have seen an improvement in the way my dog takes the stairs and overall movement. He is around 10 years old and has done well on these. One problem is he gets very GASSY from taking this product. I know it's from the supplement, because when I forgot to give him them for a few days.....no gas. Once he was back on them, it was every man for himself! The odor was overwhelming. I am stopping for a couple days, but will probably start up again. I was wondering if anyone's dogs have had this issue also?? There must be something in there that upsets his stomache. 🤭
