Customer Ratings & Reviews

Rated 4.7 out of 5 by 146 reviewers.
Rated 5 out of 5 by This product is great for painful arthritic hips on our dog. Our yellow lab Emma always loved to run after a tennis Ball and I mean she runs like the wind. Now she is fourteen years old and her back legs are stiff with arthritis and her heart is there to fly but she just can't run like she use to. We started giving her the glycoflexIII, and she still can't run like the wind, but she can still play with our other labs and move around without being as stiff as she was with her back legs. We love our Emma and it makes us feel tons better now that she feels less painful and still full of life. July 23, 2013
Rated 5 out of 5 by Really works! Have been using this for years on 10 yr old English Mastiff, 12 and 15 year old cocker spaniels who both stepped in armadillo holes and torn acl and miniscus, one has bad arthritis in hip - age made surgery not an option. They love the taste and eat it like a treat. I highly recommend this for your dogs if they have joint related pain. February 6, 2014
Rated 4 out of 5 by So far, so good I have a dog with bad, slipping knees. The vet recommended this product, although in pill form. We already give treat style glucosamine, so to make things easier with our other dog, we went with the chews. Our dog LOVES them! He is so excited for his "treat" after meals. I find that they really smell, but it's a sacrifice I'm willing to live with for his health. Just wish they came chicken/grain free for if our other dog ever needs these higher dosages. April 7, 2013
Rated 5 out of 5 by Excellent I have a little Toy Pom, who is now 10 years old. When he was about 4 he could jump down and throw his hip, or leg out of placement, and cry. Our vet told us to put him on this 1 time a day, and it would help. It's not a matter of if little dogs get arthritis she said just a matter of when. Well we started using this and I can tell you, we are faithful about giving it to him and he's never had another episode. He jumps on anything he wants to as well as jumps down. I would recommend this to anyone with Dogs. It's been great, and they love them. Thanks, May 27, 2013
Rated 5 out of 5 by My dog really likes the taste of these! Recommended by our vet for our 11 year old Husky/Border Collie's arthritis. Your pricing was much better than anywhere else I'd found. Product came in really good time. Was hoping though to get the higher count bags but they were out of stock. Will try again. Helga really likes the taste of these and as we are not a treat giving family this is as close as she gets! We have been noticing a marked difference in her ability to get up and move and hope with these that she will continue to improve. April 18, 2013
Rated 5 out of 5 by Great glucosamine product! We have tried so many glucosamine products out there and this is my dog's favorite! She loves the taste and does not hesitate to take it. With other chews and pills we had to hide it in cheese or peanut butter. For the price and quality, Glyco-flex chews are the best. March 5, 2014
Rated 4 out of 5 by Very happy with this product I have a 11 year old lab that suffers from arthritis. He weighs 85lbs so he is a big guy. I really like this company and currently use this company for another dog that I have. She uses there bladder strength and has done so for many years, with great results. It was a no brainer to turn to this company for joint support. They use good mostly natural ingredients and that it is a complete joint supplement. They also offer different levels of support depending on how bad the joint issue is. These are a soft chew that are bone shape that seem irresistible to all of my dogs. My lab eats them without any problem but then again he is a lab. I have 5 dogs total and gave everyone a taste and everyone ate it without hesitation. The other nice thing is that after the loading dose this bag will last me a month so not a bad price for a high quality joint supplement that is easy to give. Over all I have seen improvement in 2 short weeks and hope to see more. August 3, 2013
Rated 5 out of 5 by Amazing Stuff My 10 year old Samoyed has been on Glyco-Flex III for over a year. Her arthritis has improved to the point where she is having no problems getting up or jumping up (on the bed and into the car) her movements aren't slow and she is running around and acting like she did when she was a youngster!
