"I have kept Grand Flex in my barn for over 15 years with consistent good results. I am convinced my vet bills are reduced by the lack of joint and digestive problems we now have. As a trainer working with a variety of breeds of all ages and disciplines I researched many products to find a QUALITY supplement that was effective and simplified our feeding program – my clients couldn’t be happier."

My students appreciate the Rewards Arena Program and all the great gifts they earn off the Reward Points. Grand Meadows is the best!"

"I have been feeding Grand Flex Joint Supplement to my 8 year old German Shepherd for over a year now. When I first started, he could barely climb the stairs – now, I can take him out hiking without worrying that he will be in pain afterwards. Thank you for giving me back my hiking buddy!"
