Rated 4.8 out of 5 by 81 reviewers.
Rated 5 out of 5 by Possibly helped us avoid surgery? My dog suffered a knee injury at a fairly young age. The vet said that she was on the borderline as far as weight goes, and that either surgery or conservative management were viable options. I bought the GlycoFlex III and went the conservative management route. It took a couple months of being very careful and using the more intensive dosage, but it seems like we won't be needing an ACL surgery. She runs, jumps, and all traces of a limp have completely disappeared. I know it's difficult to assign credit solely to this product, but if you're facing a $5k+ surgery it sure can't hurt to try. If you do opt for surgery, the price of the supplement is a drop in the bucket towards a healthy recovery afterwards. October 11, 2016
Rated 5 out of 5 by Senior Joint Support I purchased the VetriScience GlycoFlex Stage III Senior Joint Support Dog Tablets, and I have to admit, I was skeptical at firs. But honestly, after almost two weeks now, I actually see significant improvement. My old boxer boy is 12, so of course there's been a lot of slowing down in him, but he was even having a hard time climbing in the car and onto the couch. Not any more. He jumps up like a pup and wants to play catch and run all the time now! He's got swag back in his trot! October 4, 2016
Rated 5 out of 5 by Great product Helped my boxer tremendously. Will continue to give him Glyco flex stage III. September 30, 2016
Rated 5 out of 5 by In a word...amazing!!! My Great Dane seems to be feeling much younger than his 8 years. He was diagnosed with osteoarthritis in his spine and did not even want to go outside. Now he's running around like he did when he was younger and playing with his brothers and sister. September 26, 2016
Rated 5 out of 5 by Seems to be working! Purchased to ease joints on overweight black lab. Seems to be working in a very short time. Worth a try. They are huge but he thinks they are treats so easy to get down him. September 11, 2016
Rated 5 out of 5 by This product has been helpful Need to find out if these come in soft chews for my old dogs. But I do see a difference in them after the first week. Needs to get in their system. I hear that soft treats they just eat. These I need to put in something. Like cheese. So I'm hearing the soft treat is they way to really go in this. I don't want to grind in their food. If they won't eat it out of my hand, I don't think it's fair to put in food every day if they don't care for the taste. In a treat will do or put in piece of hot dog. Make a slit in the hot dog and it's a pill pocket. August 15, 2016
Rated 5 out of 5 by I have seen a change in condition I began using this product on my 11 year old greater swiss mountain dog who was showing her age in her hips. Two weeks after a daily dose my dog began to climb the stairs nightly to sleep in our room again after 18 months of staying on the first floor. She also began to show more interest in walking the block again. This product was the only change in our routine so I am positive it is making a difference in my dogs condition and comfort.

Rated 5 out of 5 by Very happy with results Since starting GlycoFlex 3 a little over a week ago, my grumpy old man (11-year old shepherd mix) has been a lot less grumpy and often acts puppyish! My goofy old man (11-year old lab mix) is even goofier! August 26, 2016
