Clinical research shows GlycoFlex 3 can increase hind-leg strength by up to 41% in just 4 weeks, making it one of the most trusted solutions for canine joint care.

Awesome supplement for back issues
Quality product, fair price, works as stated …. a great supplement for my aging dachshund mix, with her back issues. Seemed to give her More pep in her step, seems to be in less pain when jumping up into bed …. Vet recommended also

Great product
In tears this morning noticing the emense difference this supplement has made in my dog in just a week. My little buddy has been suffering for so long with no vet helping, just saying to take him to swim and message. In just a week Kyle has began wagging his tail again, and is starting to gain control of his wonky back legs. This morning I woke up with hope for him and his recovery.

Work beautifully!! Will be reordering!
We moved recently and our 5 year old Basset had more steps to go up and down. She was very stiff and achy after three days so I did some research and settled on these. Within two days of two “treats” a day, she was bouncing up the steps and moving much easier. She now reminds me of her morning and evening “treat”! Bassets are notoriously picky eaters and she loves these. They also can have tummy issues and she has not shown any signs of distress. I will be reordering them so we never run out.

I think it worked for my dog…
On November 7th, I woke up at 5:00 A.M. as usual and got my dog out of the bed. He is a 9.5 year old Cairn Terrier / Dachshund cross that we got from an animal shelter about 8 years ago. Even though his legs are short like a Dachshund, I swear they have built in springs and he could always jump 3.5 feet straight off the ground onto my bed or from a lesser height on to the couch. The problem is that he’s always jumped OFF the bed (3.5 feet) for years even though he has stairs (he doesn’t use them). I’d always commented to my wife that he would probably end up with joint problems one day. What I didn’t realize was that he would end up paralyzed from a back injury. On November 7th, I got a quick (and traumatic) crash course in dog paralysis from disc problems in the back. As I said, I got him out of the bed. That morning, he did not jump from bed to the floor. I picked him up and sent him outside with his brother (a 10 year old Yorkie / Schnauzer shelter rescue) and he walked outside fine under his own power. When I went to let him in, he was dragging both back legs and couldn’t move them at all. I rushed him to the vet who gave me the bad news. His two options were a $5,000-$6,000 back surgery with no guaranteed results, or crate rest and laser treatments. Given his age and the no guarantee of results, we opted for the less invasive treatment. It’s important to know that even fully paralyzed, he never lost deep feeling in his paws (very important!). He stayed at the vet until Friday. I found these pills quite by accident while doing research on dog back injuries. I read the reviews and decided to order them for giggles…if I got any benefit from them it would be an added bonus. He came home Friday, and the pills arrived on Sunday. I began giving them to him twice a day. Put a dab of peanut butter on the pill and he scarves it right down. After a week, his tail started to wag again (he couldn’t even move it.) After two weeks, he started moving one leg, and after three weeks, the other leg. At 4 weeks, he began walking again (very slowly and wobbly but walking on his own.) Now at 6 weeks, he’s running (if we don’t catch him in time) and has managed to jump on and off the couch again when we weren’t watching. He’s still a little wobbly, especially in his right leg and the vet says he may reach a plateau in his healing and recovery. I’m not sure if it’s the crate rest, the laser treatments (we did about 5) or the Vetri-Science. I’m willing to say that the Vetri-Science at least partly contributed some to his recovery. Even if he never returns 100% back to where he was pre-injury, I’ll take it! He’s mobile and can go outside and use the bathroom by himself. He gets around fine. We still crate him at night and when we’re gone. If we’re home, but not watching him, he gets crated. I can’t trust him not to jump up and down and he’s gotten his jumping skills back! Give the Vetri-Science a try! For this price, you can’t go wrong! (Important Note: We were originally giving it to him with wet dog food by sprinkling it on top of the food. Not sure if it was the food, the medicine, or both, but after two weeks we went through a 4 day period of diarrhea that was awful. He’s always eaten dry food since we’ve had him, so we think the wet food was TOO rich for him. We started giving him the pill with peanut butter on it and he scarves it right down. He eats his dry food and takes the pill 2x daily and no more diarrhea since we cut out the wet food.)

Worth the purchase
A regular purchase. My old girl can’t go without these. These have been a lifeSaver, and have added so much more quality to life for her ailing hip and joints. 💕👍🏼

Made a Real Difference…
I first found VetriScience chews when I adopted a 15-year-old rescue who could barely walk. She was always a bit stiff, but after being on these for a while, she was running again. They also helped another senior dog we lost a couple years ago, and now my current older dog takes them too.The chews are about the size of a quarter, and my dogs like the taste, so giving them is easy. The smell isn’t unpleasant to me. If anything, it actually helps me tell the chews are fresh. They’re mostly sturdy, though some pieces break apart near the end of the bag, so I keep an eye on that.They’re pricey, but for me, it’s worth it to help keep my dogs moving comfortably. I trust VetriScience, and it seems they’ve improved the packaging recently—the new bags keep the chews fresher longer. Before, they’d dry out halfway through, which was frustrating.It’s hard seeing your dogs get older, but these chews have been a real help. I honestly don’t know what I’d do without them.

Magical! My elderly bulldog is refreshed from barely walking!
2 weeks, 2 Short weeks – and my dog is feeling like a new dog!! I have an old (8yo) English Bulldog who was already getting stiff. Then he survived a heat stroke but has some ugly after effects showing up. He could barely walk and was clearly in a lot of pain and I was teetering on the unthinkable because I don’t want to watch him suffer. But I happened upon this product, and although not my normal price range, I decided to give it a try. It’s been 2 weeks of 4 tabs a day (oh, and he actually eats them without having to be tricked with some other food around it!) He is now back to just a little stiff, but walking across the yard again for all of his “smells”, hopping back up on the couch (he couldn’t for a while) and today he even had a couple little bouts of a “trot” when he could barely walk himself outside to go to the bathroom just 2 short weeks ago.So if your dog has a joint problem, from age or type of dog he is, or even an injury – grab you a bag and maybe see the same unbelievable results I have. We have tried so many “chews” over his lifetime – most of which he refuses to eat – and had little to no results until NOW

I don’t know if these have helped. I got them for a young rescue gsd who hadn’t gas the best start in life and came to us very underweight. It has given me piece of mind that it’s helping her joints as she grows a bit more and puts the weight on.Update: after a pack, the dog was much less stiff. I didn’t get another and about a year later she started showing signs of stiffness, a bit of a limp after a long sleep etc so got another. Sorted, all limber again so I’m convinced. Changed from 4 to 5 star (just wish they were cheaper!)

Un cambio total en la salud de mis perritos, tengo un schnauzer de 13 años que se vio increible mejoria al caminar 100% recomendado
Dog Walker Lady –
My spaniel dog had ruptured discs and went paralysed in back legs and now has IVDD. He had the operation and took 6 weeks to walk again. He’s been on this for around a month now, together with Yumove. He does seem to be getting stronger. I will keep using this, just in case it is this that is helping.UPDATE AFTER 2 YEARS OF USE: My boy has become so much stronger and I think these really do help. I switched from Yumove to Glycoflex 3, so now use both VetriDisc and Glycoflex 3 and they really do help him stay strong and enjoy life.
