⭐️⭐️⭐️⭐️⭐️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 dogshearts, 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.

No more lameness

My dog suffers with luxating patella and had some pain and daily lameness on his back leg. Since he has been on flexi k9 he has been a lot more active and doesn’t have any lameness! I’m so pleased he is more active and not in pain like before �

I’ve been able to take my 13 yr old Chihuahua Pixie off her anti inflammatory drug she’d been on for years. She just has 1/4 teaspoon of powder in her food once a day. Great result. Thank you.

My older dog (10) had knee surgery last summer and I started giving him this with the calm and he is moving much more like a younger dog.

Since using Flexi-K9 my Molly who was an intense, hyper and reactive dog has been transformed into a really calm, loving and affectionate dog. Molly is a young adult dog but as the breed (GSD) is renown for back problems I wanted to make doubly sure that she would live a long and healthy life. The change in Molly since taking Flexi has been amazing and if I had not seen the transformation I would never have believed it possible. .

Only on first pot so diff to assess but my 3 yr old Lab is active with no obvious mobility problems so hopefully Flexi will maintain this

  • 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”
