Rated 5 out of 5 by Love the product I'm glad we are using this company. We plan on making another order soon January 7, 2017
Rated 5 out of 5 by Works great My dog loves them. Thinks they are treats. Could see improvements within 2 months. January 4, 2017
Rated 5 out of 5 by I am very pleased with the results of this supplement Both my husband and I see an amazing difference in our dog. She only had mild symptoms of occasionally appearing stiff from resting after her Agility classes. Now we don't see those subtle signs and she seems like a younger dog. We have only been using GlycoFlex for a couple weeks, but we are very pleased. December 5, 2016
Rated 5 out of 5 by Amazing Results! My 12 year old Lhasa-poo had been experiencing increased back problems for about a year. He would frequently pull a muscle and spend weeks on anti-inflammatory medication recovering. He wanted to play with our new puppy but would injure himself whenever he tried, so he would spend most of his time just watching her from the sofa. We started Glyco Flex II two months ago after doing extensive research on its possibilities. Since this time, my dog has had zero back problems. He now runs around the house playing tag and tug with the puppy twice a day and recently started chasing the squirrels again (which he has not done in years!). My sister-in-law is a massage therapist and was amazed at the improvement in his connective tissue and muscle structure, commenting that his muscles now feel like those of a middle age dog, not a senior! I was not expecting such significant results when I ordered this product. I am overjoyed and enthusiastically recommend it! December 4, 2015
Rated 5 out of 5 by Bad hips for an 11 year old black lab Luke is our beloved 115 lb 11 year old black lab. He has been taking the chews for his hip pain for the past two weeks. He seems to be much more comfortable. It may be a little bit more expensive but worth it. Thank you! October 12, 2016
Rated 5 out of 5 by Dogs love these treats Flavor dogs like the taste and helps the joints They look forward to it daily October 16, 2016
Rated 5 out of 5 by Dogs love All 3 of my dogs can't get enough of these! They don't care that it is medicinal and are limited to how much! Besides the dogs loving these I do believe it has helped with at least one of my dogs who injured his leg and 2 weeks later is now walking on it. September 18, 2016
Rated 5 out of 5 by Really helps my dogs' joints I've been giving this to my 9 year old dogs for a few years after my veterinarian recommended it for an elderly foster I had at that time. I started giving it to my dogs as well, and I see a great increase in their mobility. Highly recommended. July 17, 2016
