Joint Flex has been helping my older Australian Shepherds who suffer from arthritis. I also have a 19 year old mare that has arthritis that I am giving this to. She has improved since I've started giving her this and a joint supplement.

My 10 year old dog seems to have found his puppy energy after using Joint Flex!
Rhonda S.
Within the first few days there was a noticeable difference in my Duke's ability to move with much less pain. So thankful I found this product.
DIANNE D.
My 12 year old Australian Shepherd was having issue getting up. She was dragging her back end until she could finally rise up. She no longer does that. She is back to chasing bunnies again!!

Great product

Addy is my Great Pyrenees and she guards over 40 acres. She had got to where she was having trouble getting around. I got the joint flex and it has made a huge difference. Love this product

Great product, has really helped my stiff and sore senior dog.
Breauna H.
I have a senior pitbull/bulldog mix that was having extreme problems with his back hip! Joint flex has helped him be able to move some more, he’s doing things I haven’t seen him do in 7+ years!!
Tamie W.
Works great for our lab.
Denise H.
My 3 year old pup has OCD in his right shoulder. He’s been on this joint flex for almost three years. It was recommended by his vet. He hasn’t limped for months… I have a new pup and have started her on this also. Both are large breeds prone to joint issues. Praying this will keep their joints healthy and pain free.
Jenn F.
My daughter started me on the equine version then we went to the canine and love them both
Barbara S.
Norton, age 10-13, and Ralphie, young, have tons of energy and play all the time. My granddogs Tig and Rooster ((both over 14) are slowing down but are pain free and enjoy slow sniff walks.
Krista M.
We love this product! We use it for hours and our dogs!

My dog recently had a TPLO and needed some support recovering from surgery and helping to manage his arthritis. Within 2 weeks of starting, I noticed he could walk better and was much less painful! He will be on this for life! Great product.

My 10 yr old shaky hind legs dog is still able to walk and run.
RuthAnn H.
Our precious dog Molly is a rescue that was brought into our life 12 years ago. They think she may have been 3 at the time. She is the greatest blessing of all.
Aging is happening of course --- legs and hips strength is challenged. We started proving her with canine joint flex and it is visibly improving her gait and attitude.
I'm very grateful
Rob I.
The only thing that is working for my shepherd with arthritis. Within a week he’s no longer whimpering every time he gets up and is able to get in the car u assisted.
Karen B.
This is the joint X for dogs. I see an improvement already!
Elizabeth D.
100X Joint Flex has helped my sweet older puppy (10 1/2 yrs old) move around so easily, despite her age/breed combination!! Her younger siblings really like it too!
Shanna A.
My dog has seen great improvement from this product.
Paula W.
Old dogs with some joint issues. This stuff makes it more fluid for movement. Love it
Carolyn S.
My Doberman Pinscher is 12 years and 8 months and has severe arthritis. I've been giving her osteo max for about 5 months. She went from hardly being able to walk, to getting around, and going outside to potty by herself. She is on medication also, but I've seen improvement even though she was on medication. I give osteo max to my other Doberman's as they are competing in dog sports on weekends. Great product even though it's for my dogs and not a horse.
Thank you for prolonging my Doberman's life.
Theresa S.
My Malinois dog had a torn Achilles tendon which required 3 months in a soft brace & he had no use of that leg at all. His back leg laid flat to the ground from the elbow down. A $6-7000 surgery was recommended with no guarantee of full range of motion. Read an article re: this product & immediately began its use. A remarkable improvement in about a month. Now give it to my GSD as well for her developing arthritis. I have no doubt that this product improved the healing time of the Malinois.
Leanna C.
Love it
Jessica W.
My rat terrier was diagnosed with patellar luxation by 3 different vets. All stating she needed immediate surgery. She was only able to walk on 3 legs and yelping randomly from the pain. Knowing the results after starting my arthritic gelding on joint flex how well it worked for his pain, I thought I would try it on my terrier as well. Gradually noticing a difference week by week, she started walking on her leg again! 2 years later and no surgery needed! She now runs like a pup, chases balls, leaps in the air to fetch sticks! She is 7 years going on 8 now and I will keep her on joint flex for life! I seriously can't thank you enough for your products!
Christine T.
Ringo has had two TPLO surgeries and is still running and chasing birds and playing with his doggie buddies.
Ross H.
Joint flex has been life changing for Bayley! She was experiencing the common hip issues Labradors have as they age. She went from being carried up the stairs to running in the safe brush. Thank you 100 X
Equine❤️!
Justin C.
Wonderful product it took our 9 year old Great Dane mastiff mix from not being able to fetch or go on walks without limping to how she was when she was a puppy no limping at all
Jessie T.
We noticed that Petunia has increased mobility and reduced stiffness after 2 months of using this!
Hilary S.
My dog seems to have better mobility and stamina as a result of this canine joint flex
Melissa B.
My husky mix Jetta had two knee surgeries by the time she was two years old.
She was on a regimen of supplements. They did help for a while. Last month I noticed her struggling to get up as both the surgeries are on the front legs. A great friend recommended this product and shared some with me. I literally noticed a difference in three days. It is now been a month and a half, and she greets me at the door like she did 10 years ago. I am really amazed it has been quite miraculous!
She is 14 now but does not act like it whatsoever! Thank you so much
Britta W.
Joint Flex is the one thing that keeps this dog going! He goes 100%, 110% of the time! It keeps his joints good and helps recovery of injuries he constantly sustains.
Tracy L.
Great product. Used before with a senior horse. Now using for my senior dog. Definitely works. I could see a difference in stiffness and discomfort within two weeks.
TERESA S.
Our old yellow lab gets around so much better!!
Andy P.
Really seems to have helped with my dogs stiff joints. He is able to get up much easier and back to running and playing.
Sarandy P.
my dogs mobility improved within the first 48 hours of taking 100x. I tried everything (i’m a bioenergetic practitioner) from frequencies, customized lasers and CBD. She got her hind leg caught in the fence and really messed it up. still a little limp but it’s a nice daily reminder to her that she is no young pup
Jamila L.
My 15 year old german sheppard does well with flex joint. She has been on it for about a year now and you can tell a differece when she is off the product. Seems to work well on her joints. I highly recommend trying the product.
Sherri S.
This product helps my 8 year old mixed breed dog. He used to limp very noticeably and the vet said he has arthritis in his shoulder. Since we started him on Joint Flex, you can hardly tell he limps at all. We tried other supplements, but they gave him digestive issues. Joint Flex has none of those issues.
Charlene G.
Sugar (Bullock) has arthritis and hip displacia. Since using this product she gets around great.
Ellen C.
Our 11 1/2 yr. old Golden Retriever has been a tripod since she was 4 months old. She was having some tough times the past year and would stumble and fall when she would get excited and wanted to run. She's been on the Joint Flex for about a month and seems to be a little more active. She helps me with chores every day and actually comes into the pasture more often while I pick up manure. Although she keeps an eye on the ornery burro. I'm hoping she keeps improving as time goes by.
Judy J.
Been using your products for years. My dog got injured playing in the arena one afternoon and for over a month and numerous vet visits. We could not keep her comfortable without being on anti-inflammatories. I decided to try your products and she has been pain-free for four months now
DIANNE D.
My Australian Shepherd, Miss Roo Bear, is 12. She has been having trouble getting up. She was dragging herself before she could gather her legs underneath her and stand. I have been giving her the Joint-Flex Canine for just a week and have seen a big improvement already!! Thank you so much for giving my sweet girl some desperately needed relief from her arthritis!
Karen L.
Switched to this joint flex and saw almost immediate improvement. He is walking much better and seems to be in a better mood.
Thank you for your wonderful products.
Ashley G.
My dog is 11 years old and showed an increase in mobility after using this product. He gets 2 pumps per day with food.
Rachelle
Seems to help but I'm using it in conjunction with other products so I'm not sure it's singular effectiveness
Shanna N.
My dogs are on the Canine joint med and my three horses are on the GutX, Joint Flex, Max Calm and OsteoMax. They work great. Love the products. Keeps them doing their best when showing.
Sherry M.
My Great Pyrenees was having lots of joint issues, it was sad to see her limping around. But I ordered the canine joint flex and there is a huge difference. I highly recommend getting this for your fur family

It is a real plus to be able to feed a reliable source of hyaluronic acid to my old dog. Your product and its very fair pricing are very much appreciated!
Deanne E.
After years of using 100x on my horses. I decided its time to give it a go with my aging dog. She had been on Joint Flex now since June 2025. She has energy to keep up, jumps in back of truck and isnt limping or having troubles going up and down stairs anymore!!
Jane H.
RAINEE is a 13 year old miniature 10 lb Dachshund who recently started yelping if she was picked up or tried to play. Vet treated with pain meds for a short time. I ordered Osteo Max & Canine Joint Flex. She is doing great & no more yelping!! She loves her supplements!
Manuela K.
Since I started my older dogs I have noticed that they play run more
Kathy P.
Okee is 9 years old. He competes in AKC obedience and rally. Okee has qualified for AKC Rally Nationals 5 years in a row. Okee is also a ranch dog, helps move cattle so they go in the right direction. Most important, he is my best friend.
Carlene O.
One of my German Shepherds has cruciate ligament disease and we’ve already spent $6000 for TPLO surgery on one leg. About a month ago he started limping on the other leg. Someone in a CCL group on FB recommended trying your products so I ordered the Canine and human versions. Along with all the other supplements I have him on and now this one, his limping is getting better. We are only allowing short leash walks for now but he seems to be rebounding quicker after a short walk. I am praying this product will help us to avoid putting him thru another major surgery. Plus I am taking it for my own arthritis! I just had meniscus surgery and hoping it will help with my aches and pains also! It is too soon to know, but I will continue to reorder. I was really impressed when I got a phone call from a representative of this company after my order. They really seem to care about all animals and believe in their products.
Cindee R.
This stuff is great!
Sherri S.
Hoping this will help my rescue dog with his hips.
Diana T.
These products have helped both my 31 year old horse and my 15 year old dog.
Long T.
Our Great Pyrenees was struggling with his joints and we decided to try this product we also went with a veterinary shot to assist with pain management, between the two this has been a complete difference in his mobility!
Amanda B.
I love your products. I have both horses on gut x and I have just started my old boxer (she’s 12) on the canine joint flex. After a week she’s definitely feeling better . I’ll keep her on it.
Thank you for your products , I’m always excited to read about anything new you bring out. Your stuff works
Michele B.
THANK YOU THANK YOU THANK YOU for this amazing Joint Flex product!!! Our 11 year old Boxer has arthritis and I’ve tired other supplements recommended by our vet until I called you guys to ask about giving Joint Flex to my dogs. I give it to my horse and have seen amazing results so grateful it was safe for my Boxers!! You’d never know our 11 year old girl is her age because she acts like she’s 2! We also LOVE Joint Flex because our white babies have many allergies and this is the only supplement that doesn’t have any animal flavoring!! We give them their dose in their dog food twice a day and it’s been fabulous!!! This is a MUST for anyone with fur babies or even yourself!!! ❤️
Gigi K.
Been using the Osteo max and Gut for over heat and has worked beautifully for my older horses. Thought I would you the supplements on my German Shepherds they both have joint issues due to age! Love it! What a difference!
Tim H.
Gus is almost 6 years old and started showing signs of hip and joint problems, he couldn't get into my truck without help and refused to come in the house because of slippery floors. After 2 weeks of taking the Osteo max and the Gut x he was jumping in the truck again, slower but still major improvement. Gus has been on this now for over 1 month and he is back to 100% this is the best product I have found.
My wife and I are both older 63 and 65 I have had a torn rotator cuff for over 12 years and couldn't lift anything above my waist as well as the normal pains and swelling from my knees and hips. After 2 weeks my wife could see a major improvement in me and I can lift over 25 pounds above my head with my bad arm. It has been over a month and both my wife and myself are doing better than we have in years. I can't talk to anyone without promoting this product as it has been a major life improvement for us. Thank you 100 x equine. Their customer service is also second to none as they reached out to me the day my product was delivered and answered all questions I had and gave me Their number to call for any questions I might have, great people and great product.
Susan G.
Looking forward to positive results for my 3 dogs who have arthritis and mobility issues.
Elizabeth M.
Received the canine joint flex as the winter gift! Wow what a difference. My little Deerhound has really bad hind hips. A week ago all he wanted to do was lay by the fireplace under his blankie, but today we was back to walking without a limp, chasing our farm cats and acting like a 2 year old should. Thank you so much for all the great products. My horses love the taste of all your supplements, now my 4 dogs do too!
Dianna A.
We love the product.
Hilary S.
Both dogs are doing well!
Molly is 9 and Milo is 23 months he is on this as a preventative as he has no joint issues yet
Molly is now keeping up with Milo and playing much more! She had been slowing down and has an existing knee issue which doesn’t seem to bother her as much now. Great product!
Lori H.
This seems to really be helping our senior hound. She seems to be moving more easily with less pain.
Erica B.
I'm using this for my senior dog and my mom's senior dog, both of whom have joint issues. My dog has luxating patellas, and I've been giving him jointX for many months now. It's helped, and at a minimum, I believe it's preventing further issues down the road, like arthritis or hip dysplasia. I also started giving it to mom's dog because she has an injury, which we suspect is a torn ligament in her front right leg. I do think it's helping her as well. So thank you!
LINDA W.
Canine Osteo-Max
My 5 year old Rottweiler has a partial cruciate tear, which happened a couple months ago. The surgery to repair it was quoted at over $5000, which I don't have. He has pain meds from the vet. I started giving him the Osteo-Max about a month ago, because it says its good for connective tissue and joints. Much to my very happy surprise, I have seen improvement in that leg. He is able to put more weight on that leg and its so nice to see him walking on 4 legs instead of 3! Of course, there is a long road to recovery, but I never expected to see improvement in a month. I would like to continue to use this and see his improvement continue. The best surprise in a new product!! Thank you.
Cara W.
Definitely helps my senior pup! Shipping is always fast and easy! Thank you!
Cierra S.
Started my 11 year old dog on this. She was stiff in the back end and moving slow. She has been on this almost a month now and is moving so much better. I have now started my other two dogs on. Absolutely a great product will definitely be ordering more.
Mark S.
This is a fabulous product!
Big time improvement since starting my German Shepherd Roxxybaby, who is 8 years old on it!

Jennifer J.
We started using 100x canine joint care. Our 9 year old Aussie was having issues after playing with our new puppy. The joint care fixed it! He now runs and plays without issue!
Bridget P.
Joint flex really has made a significant difference in Pirate not limping!
sara s.
Our lab started moving better after the 1st week of being on it.
Christine T.
This product helps my 10 yr old dog, who has undergone two TPLO surgeries, run like the wind.
Vivian M.
There seems to be an improved mobility. Just starting on this with my 2 seniors.
Ginalee H.
Our Red Heeler/Lab is 13 and was moving really slow due to an old injury of his hips. He runs like he’s 2 again!

Mary P.
Love the product!
Jann H.
I gave my other daughter who has Chesapeake Bay Retriever rescue the 1/2 gal to try for Christmas as well ❤️
Catherine K.
Since starting Joint Flex a few months back, Willow is moving so much better and thinks she's a puppy again! THANK YOU for this wonderful product!
Jennifer J.
We got a puppy this year, so our 9-year-old Aussie was romping and playing more in the field. He would end up sore from his playtime. We started him on 100x joint for canines, and we have had no further issues. He plays with the puppy without issue! We have recommended it to lots of friends!
Sabrina G.
Have been using the product for a couple of weeks. I have noticed any drastic changes but I haven't noticed any regressions either. Keeping the status quo was my goal so I'm satisfied with the product. The pumper with the bottle does drip a couple drops after each use so be sure to put a cup or napkin under the spout so things don't get slimy.
Caryn H.
We adopted a GSD that we've since discovered was hit by a car and has a healing broken elbow. The joint would click when he walked too much or was as active as he wanted to be and were told about this as something that could help. The combination of this product and really keeping his activity limited, the clicking is greatly diminished and he seems to be in less pain. Thank you!
Louis C.
Worry free delivery on time.
Lisa H.
Fantastic product love love love
