    Flexi-K9 Max Strength naturally combats the wear and tear of age by keeping joints nourished and bones strong, while maintaining mobility, easing stiffness and protecting, supporting and promoting joint wellness for dogs as they grow and age (from 6 months onward).

    • All-natural active ingredients support dogs of all ages to lead more active, longer, happier and healthier lives.

    Formulated By Canine Nutritionists

    Our Quality Ingredients Include:

    Anti-inflammatory Supporting Turmeric

    Science has proven that turmeric supports the natural anti-inflammatory processes within the joint and promotes joint wellness generally in dogs of all ages.

    Wellness Boosting Omega-3 Fish Oil

    Fish oil powder has been shown to support dogs’ hearts, joints, immune system, skin and coat! Dogs can’t produce omega-3 fatty acids on their own and must get them from their diet.

    Joint Maintaining Green Lipped Mussel

    Rich in omega-3 fatty acids, minerals, essential amino acids and glycoproteins, this mighty mollusc also contains natural chondroitin - a powerful combination which supports and promotes joint health in all ages.

    How much Flexi-K9 Max Strength should I give my dog?

    Feed Flexi-K9 Max Strength based on your dog's weight, once daily. Gradually increase to the full amount over 5-7 days.

    Works

    Started using this for my 10 year old a few months ago. The biggest difference I see is him playing with his younger sister. Realised I hadn't seen a play bow and chasing around the garden for a while. Now he can move easily and is enjoying it. Plus he can get up on the sofa without help. We're both happy ☺️

    I recommend this product

    Great product!

    We have been giving this product to our 6-year-old long-backed agility dog for nearly 5 years now. So far, no injuries and not a hint of arthritis. He’s happy to eat this sprinkled on his kibble in the evenings.
