“[Our] 7 year old lab has had problems with his legs and joints from a very early age… often limping towards the end of the day if he has been running and playing a lot. To top it off he has a weak stomach and can’t tolerate many different foods.We started Sid on a small dose [and] we think Best Dog has settled his stomach to the point where there is no more horrible gas and if he eats something a bit different, it doesn’t affect him anywhere near as much as it used to. Sid doesn’t have so many problems with his joints anymore either. I would completely recommend this product to other dog owners.”
