Rated 4.8 out of 5 by 9 reviewers.
Rated 5 out of 5 by Great Product I am an endurance rider and have used Fluid Flex for years. It has kept my middle age horse that has done thousand of miles in the game. My horse is a high energy horse and we compete for best condition often. I credit Fluid Flex to keeping him sound and ready to go again the next day. Thank you. December 13, 2012
Rated 5 out of 5 by Wonderful Product I have used this many times in older horses and always been impressed with the results. My current horse, a 28yo Arab, is stiff and slow without it, but after a few days back on it he will run and buck at liberty again. I will keep him on this the rest of his life. October 23, 2012
Rated 5 out of 5 by LOVE IT!!!!!! I have used this product for years all that I can say is in the past 8 years I have been using it. They don't mess it up when they make changes to it, just gets better and better. Don't believe me, ask my Stallion. A 19 yr old Reining Horse, he gets this just one time a day during off season and twice during show season. He loves it, went from being a little slow when I first got him to being perky, and he trots and plays again. Overall you can just see that he is much more comfortable. This product does what it says you see results in as little as 2 days. The price used to be crazy, throughout the years it has dropped and I am thankful because I will never use another. Best one I've ever used and I've gone through alot. Best part of this product is that it can be used with other supplements and you don't feel like your overloading on one vitamin. Works well with taste too, never had a horse complain even my Arab who is a picky eater would scarf his food down with this on there, and it was gentle on his sensitive tummy. July 4, 2012
Rated 5 out of 5 by Great Product My TB had been acting funny, his symptoms numerous, I love this horse. He is 26 I have had him since he was 9.After 3 weeks my TB who once crumbled to the ground, and refused to ride for more than 10 min, wanted to run, trot, gallop the ride I thought I would never experience again, I rode. Thank you Farnam June 4, 2012
Rated 3 out of 5 by Bad Container I bought the largest container of Fluid Flex and it did not come with the measuring reservoir. So have something handy to measure with. March 2, 2012
Rated 5 out of 5 by Amazing product! Not only does Fluid Flex work on horses, it works equally well on dogs. I started using it on my dogs about 12 years ago & it's really helped them out, not to mention it's WAY cheaper than any canine joint supplement I've ever found. I highly recommend this product for horses & dogs alike. February 9, 2012
Rated 5 out of 5 by 24year old mare loves this product Angel had bad hocks from being used in rodeos etc. long before I owned her. Along with H/A shots in her back hocks--I have been given her this twice per day at feeding and she looks and feels so much better. She gets angry if I don't add it to her feed. She loves the flavor and really feels rejected when I am out and I promissed her that I'll never be out of it again. She loves it. You can't go wrong. November 16, 2011
Rated 5 out of 5 by Great Value I started using FluidFlex when my horse was 10 as he was already having joint problems. He is now 22 and this product has kept him going. I haven't tried anything else, so I can't compare products. This works for him and your pricing is great. December 5, 2010

I have a 14 year old,65 lb., German Shepherd with hip dysplasia. Will this be harmful to her? How would I administer this to her and what dosage would I use?
cindy c on Oct 27, 2015
Best Answer: Cindy, we have only used Fluid Flex on three of our horses. For them it has been most helpful. I would suggest however that you ask your vet prior to using this on your Shepherd. If he/she says OK, just sprinkle it on her food at mealtime in the dosage your vet suggests. Good luck
