Rated 3 out of 5 by Too Soon To Tell I am not sure what to think of this just yet. My dog has been on it almost 2 weeks which is not enough time to get in her system by any means. She was on different supplements before, so I had hoped the transition would be quick. She loves these things. I, on the other hand, gag whenever I open the bag. Wow! Do they smell. I tried the tablets of the same brand about 1.5 years ago. The dogs did not like those, so I only bought them once. I cannot recall seeing symptoms decreasing or increasing during that time frame. I do recall the smell not being so strong. If these end up working, great. If they are questionable, I may try the tabs again just because the smell is so overpowering. July 14, 2016
Rated 4 out of 5 by So far so good ... 12-1/2 year old Dog has only been on these for 1 month at this time and they seem to be helping his hip dyplasia/arthritis the best yet. Dog is practically immune to most of the well known name brands and only one would provide him considerable relief, but then it was discontinued. Go figure. He is also on anti-inflammatory and pain med, but those 2 alone did not help completely while I tried to find a joint support that would provide relief. The 3 products together seem to be the perfect cocktail. July 11, 2016
Rated 5 out of 5 by Amazing product ! Thank goodness I found this product for our 7 yr old chocolate lab. He started to get really stiff and walking like an "old man", we couldn't figure out what was going on. It got so bad where he wouldn't even get up anymore or greet us at the door. He had a hard time walking up and down stairs and we had to lift him up to get him outside to use the bathroom- we brought him to the vet 3 times to try to figure it out .. All signs were leading to hip displasia and arthritis .. I purchased this supplement as it had the highest mg of glucosamine , and let me tell you... With in a week and a half, Bo ( our chocolate lab) is like himself again! Happy, playing , walking and running ! I couldn't be happier with this product and will definitely be purchasing again! Thank you! June 13, 2016
Rated 5 out of 5 by #1 Product! We adopted our Greyhound 4 months ago. She ran 175+ races and is only 4 years old. When we brought her home she would cry out in pain just to walk. Her joints were so swollen and tender to even touch. We started her on GlycoFlex 3 joint support and within a week she was a different dog! This truly is a miracle product! Your pet doesn't have to suffer anymore. Get it, try it, see for yourself! July 7, 2016
Rated 5 out of 5 by UNKNOWN AT THIS TIME I started my oldest girl, 12, on it, but I think the vet told me too late about it. I've started my younger girl on it at 6 yrs old; she likes it as good treats. July 10, 2016
Rated 5 out of 5 by My dog loves these! My golden loves these sooooo much! And they're actually good for her! Win-win!! July 8, 2016
Rated 1 out of 5 by Product Is Worthless If Your Dog Wll Not Consume I have bought other chewable Glucosamine "Treats" for my dog who's not a finicky eater by no means before these and she will not touch them. And I don't blame she they smell like gawk. I will give the makers credit. (1) No were does it say its got a favor dogs enjoy. (2) No costumer satisfaction or your a money back guarantee. To find some thing fast I went to Walgreens and bought they brand petshoppe joint support soft chews with Glucosamine and she eats them right up. $10 60 chews. FYI Chewy.com once bitten twice shy. This will be the last Glucosamine from this site I will ever buy again. June 12, 2016
Rated 5 out of 5 by This Product Just Works! My 10 year old Chihuahua was having trouble with her back legs...she didn't have the strength to jump or even hop around like she used to when it was dinner time. I started her on Glyco Flex Stage 3 in December 2015. Within one month, she had more spunk and strength in her back legs. She loves the flavor of the chews. I make sure she has it at all times!
