Thought I’d give you an update! Almost 2 weeks in and Jed is doing fantastically on your product. He’s flying around at agility training, seems much more comfortable, more flexible and less stiff. I think after a month, he will be better still. I’ll keep you posted. I’m delighted with your product. It’s amazing! Rebecca Steenson
Customer Reviews for Canine Joint PlusHA
Scarlett has been on the 2 products you recommended for about 6 weeks and it like a miracle. She is running about and full of energy like a young pup. Getting up is no longer a problem. It is like she has had a new lease of life. Yesterday was her 11th birthday.We will be forever grateful to you and for your products.
David DavidsonVerified purchase of Canine Joint PlusHA and Green Lipped Mussel
Our 13yr old boy has been taking GLM & Joint PlusHA for a few years now and is a different animal. He was at the stage where he struggles to get up and after a couple of months of Riaflex supplements was tearing around the fields and not aching from arthritis.
Mandy GerogeVerified purchase of Canine Joint PlusHA and Green Lipped Mussel
My dog & my horse are both on Riaflex & I wouldn't use anything else now. My 9yr old Labrador has elbow dysplasia and has ACL issues. Joint PlusHA definitely helps him to feel more comfortable and active. Within weeks of using it he was noticeably happier & livelier. My 14 yr old mare is training and competing in all phases, moving well and very happy. These products are better than others I have tried previously and I would confidently recommend Riaflex to anyone. Thank you Kate!
Kate HarpinVerified purchase of CompleteHA and Canine Joint PlusHA
I used the Joint PlusHA on my 2 lovely old labradors. I would thoroughly recommend Riaflex products. The advice you can get from the Riaflex team is invaluable too.
Julie BowronVerified purchase of Canine Joint PlusHA
I don't normally comment on products but I have to say this imo is by far the best joint supplement I have used for the dogs. My old girl is now no longer on pain killers. i'm now trying the human one for me.
Jenny SweeneyVerified purchase of Canine Joint PlusHA and FlexHA
I've been giving my dogs Riaflex Canine Joint PlusHA and Devils Alternative as you recommended for a couple of months now. The results that came gradually, after about a month, but now it's obvious for us that he's doing a lot better (he's playing with the younger dog more, he's doing more free running, he's jumping in the back of the car a lot easier and so on).
My wife and I are extremely thankful for your help and for the product you have created and we will definitely make another order in a month or so. Thank you again.
Andrei MaximVerified purchase of Canine Joint PlusHA
It's been 3 weeks today since giving Denzel his supplement & I would just like to say; Thank you, want a difference! He is walking & running with no limp.
Just so pleased & amazed how my dog is feeling/looking. Thank you once again I have tried so many supplements which have not worked, but yours is absolutely brilliant.
Christine WilsonVerified purchase of Canine Joint PlusHA
Dear Kate & the Riaflex team. After ordering a 200g tub of Canine Joint PlusHA very recently as a 3 week trial size for my 5 year old 86kg rescued Newfoundland male who struggles with getting up, will only walk short distances and has no desire to play with our other adult Newfie, I would just like to thank you all from the bottom of my heart for producing such a fantastic supplement.
After 24hrs I thought he was walking freer but I put it down to wishful thinking on my part. However after 48hrs there's no mistaking the change that's happening - he's not only getting up quicker & easier but definitely his movement is freer too ( with a constantly wagging tail I might add).
On this morning's walk (72hrs after first dose) he actually proceeded to initiate a huge game of off-lead rough & tumble with our other adult Newfie in a 50 acre grass field before catching the scent of something & setting off over the horizon at a Newfies version of a flat out gallop. I couldn't believe my tear filled eyes!
Absolutely nothing else has been altered in Monty's world, only the daily addition of two and a half scoops your > Joint PlusHA. It's blatantly obvious that it's suiting him better than I could have ever hoped.
Many many thanks for giving my guy his second puppyhood! Fiona and Monty x
Fiona DonaldVerified purchase of Canine Joint PlusHA
I highly recommend Riaflex Joint PlusHA & Green Lipped Mussel. My max has been on it since he was old enough to start it and he is now 12 and walks happily for good decent walks twice a day jumps up easily on the sofa and has full active life.
All three of my dogs are on it and I find it very effective.
Theesa ManniionVerified purchase of Canine Joint PlusHA and Green Lipped Mussel
Awww Kate. I've got my dog back! Thank you!
Just a few weeks ago, Maddie struggled to even cross a road; so slow and stiff. Now she's back doing all the things a sighthound should do; chasing rabbits, squirrels and cats! The turning point was when the dog who so uncharacteristically was walking slow to heel, suddenly saw a ginger cat and let loose. Seeing her run like that brought me to tears. The cat survived and I knew my dog was back!
Thank you so much. I'll never be able to thank you enough.
Keep up the good work. You are changing the lives of dogs and their owners for the better. Well done!
Alma NunwickVerified purchase of Canine Joint PlusHA and Green Lipped Mussel
I bought some canine Joint PlusHA and Devils Alternative at Crufts. As my dog was on another brand for years but she had got worse again with stiffness and limping and back on hydrotherapy.
I just wanted to say so far the difference seems amazing. Thank you so much.
Kirsty CroucherVerified purchase of Canine Joint PlusHA and Devils Alternative Canine
Just to say a big thank you for your products. The devils claw really helped post surgery and allowed the pain to be controlled a little in order for our dog to put weight through the leg a little to aid recovery. So now she is 2.5yrs old and on Joint PlusHA and Green Lipped Mussel.
Thank you again! And your support and knowledge has been invaluable!
