Flexi-K9 | Supports Joints for Better Flexibility and Mobility

Just like humans, as our dogs age, their joints age too. And once one joint is stiff, our dogs start to move differently, increasing the wear and tear on their other joints, so those become stiff too.

So often, older dogs - and even younger dogs who have sustained injury, or those with a disability - find themselves in a vicious cycle of stiffness and reduced movement, and then, the less they move, the stiffer they become!

Seeing our dogs struggle with mobility and grow older is hard. That’s why our team of vets and expert nutritionists put their heads together to create a joint supplement bursting with active ingredients to not only support the natural production of joint lubricant, but also to boost the body’s own anti-inflammatory processes!

Whether you’re protecting your dog’s joints as a puppy (6 months and older) or supporting them as they age, adding Flexi-K9 Max Strength to their diet will help keep them moving, strong and flexible – for as long as possible!

Yes! Flexi-K9 Max Strength is recommended for all dogs. The only thing that affects the daily dosage of Flexi-K9 Max Strength is your dog’s size. See our feeding info chart for more details.

Flexi-K9 Max Strength is packed with joint-loving, movement-supporting ingredients, all chosen to help your dog stay active, comfortable, and ready for everyday adventures.

Each scoop delivers a powerful blend of:

Glucosamine HCl – one of the most trusted ingredients for joint care and cartilage support

Green Lipped Mussel – rich in Omega 3s to help manage stiffness and support joint lubrication

Boswellia Serrata – a natural plant extract known for its anti-inflammatory benefits

Fish Oil Powder – a source of healthy fats that supports mobility and joint comfort

Hemp Protein – plant-based support for muscle and tissue recovery

Collagen – helps support joint structure, skin, and coat health

Turmeric & Bioperine – natural antioxidants to help manage inflammation, with Bioperine enhancing absorption

Chicken flavour – for a taste dogs love (no fuss at mealtimes!)

It’s a daily scoop of proactive joint care for dogs of all ages — especially active dogs, large breeds, or seniors who need extra joint TLC.

Yes! This works with any diet. The formula is gluten free and is designed to assist your dog’s gut – not upset it!

We’ve produced Flexi-K9 Max Strength as a powder supplement so it can easily be added to your dog’s daily food. Simply measure and mix! We love to spread ours on K9-Calm Mats for an extra calming boost.

Flexi-K9 Max Strength contains a blend of ingredients designed to support joint health and reduce symptoms of osteoarthritis in dogs:

Green Lipped Mussel

Clinical studies have demonstrated its beneficial effects on movement and its ability to reduce signs of osteoarthritis [1].

Omega-3

Omega-3 fatty acids are believed to reduce the levels of pro-inflammatory substances and cartilage-damaging enzymes in the body, supporting joint health [2].

Turmeric

Studies suggest that curcumin, a compound found in turmeric, acts as a powerful anti-inflammatory agent for dogs suffering from osteoarthritis [3, 4].

Boswellia

In humans with osteoarthritis, research indicates that Boswellia may:

• Relieve pain and stiffness.
• Improve joint function.
  Studies also suggest that Boswellia helps prevent the deterioration of cartilage and joint tissue [2, 5-7].
