⭐️⭐️⭐️⭐️⭐️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.

I have a subscription as was told in the advertising that this is the cheapest way to buy and rewarded my customer loyalty. However, as I have 2 items on subscription I cannot hold one, it is both or no hold. Worse, when you see discounted multipacks cheaper on sale….no subscription cheapness ir loyalty. So stopped the subscrand bought the offer. Good for me, absolutely what any company really wants, utter madness…. Like the product, my dog is better for using it.

My eight year old is a lot more agile and doesn’t walk with her standard mild arthritic limp when she on Flexi. Tried all of the other supplements and this is the only one that works for her!

I purchased this for my 6 year old 150 lbs Newfoundland trusting that it would help her have happier and healthier senior years. To my delight, even now she is more playful and energetic! I highly recommend it!

  • 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”
