⭐️⭐️⭐️⭐️⭐️5 Stars! Made a Difference!

"My dog is getting up there in age and I started seeing small signs of arthritis. After only one week of being on Flexi-K9, all those signs have disappeared! Now my boy is keeping up with my younger dogs and he is happy to play fetch and tug like he did when he was younger. All my pups are taking it now. I am so happy with the results."

As our dogs age, they become less flexible. Joints begin to stiffen as the amount of lubricating fluid decreases and cartilage becomes thinner, making activity levels decrease as movement becomes more difficult.


When signs of aging, wear and tear and degeneration set in, we will help you get your dog back on their paws again.


Flexi-K9 helps to maintain your dogs youthful vitality by promoting the natural production of joint lubricant as well as supporting the bodys antioxidant and anti-inflammatory processes. By combining 6 active ingredients in a handy scoop per day, see what the benefits are for your dog:


      • Transformational Turmeric & Black Pepper: Science has shown that Turmeric that turmeric supports the natural anti-inflammatory processes within the joint and promotes joint wellness generally in all ages. Turmeric contains 5% Curcumin, which is the main active ingredient, best known for its powerful anti-inflammatory and anti-oxidant effects!
      • Green Lipped Mussel: Green lipped mussels are rich in Omega 3 Fatty Acids, minerals, essential amino acids and glycoproteins and contain natural Chondroitin, all of which support and promote joint wellness in all ages.
      • Fish Oil Omega 3 Fatty Acids: Fish oil powder has been shown to support dogs’ hearts, joints, immune system and skin and coat! High in omega-3 fatty acid which are an essential type of fat that helps your dogs body and brain. Dogs cant produce omega-3 fatty acids on their own and must get them from their diet.

My senior rescue dog was quiet and feeling his age… he then tried the powders and it is like he young again, happy wagging, running more… and oh more wags! My husband looked up the ingredients and says he wants the human equivalent!

the best

we have used other joints products and found that even though the diet for my dog hadn't changed, they gained weight on this product weight is stable ? so that's good - three months ago my dog broke her tail lots of vets visits and x rays and advice to remove her tail over the last four months - along side vets medication for pain relief - we have used this flexi - her tail has repaired and even though its a way to go - its wagging and healing - and thankfully we didn't have it removed .I do atually think this is an excellent product to help with healing along with love and care for my dog

Bought for a Young very active dog. Never had any joint issues so hopefully it will stay that way given that he’s had flexi for 8 weeks and after a very active, off-lead hiking holiday there’s no hint of him slowing down!

  • There’s a lesson for that

    Karl achieved off-leash freedom!

    Owner, Lynn said “We are going through a unsettled time at the moment, we are moving and there are lots of different people in our house as well as cars, noises etc. it’s not easy but I would not like to think of how he would be without Calm-K9.”

  • There’s a lesson for that

    Mabel learned she didn’t need to get involved with every dog on her walk!

    Owner, Maria said “Such a big improvement already – I can tell that this is really going to facilitate her training and allow her to focus more! We will definitely be continuing”
