We are using this for our 10 yr old Aussie who has arthritis in his elbows and shoulders. After 2 pots I notice a marked improvement in his limping (there is none- even after some moderate fetch)

I love it because my dogs love it. Auto ship makes sure I don’t run out. I’m m very pleased with the ingredients as well.

A supple dog aids longevity, health & fun. Our 14 year old Retriever moves around much more easily (on his 3rd pot of Flexi-k9)

This product works

I was very sceptical as to whether this supplement works. I have an elderly chihuahua who has had congenital knee problems all his life. He also now has a heart condition and was really struggling to move around. Since he has been on Flexi-K9 he has a new lease of life and is even able to jump on and off the back door steps. I have only given him the supplement.There has been no change to his medication or diet so I can only assume this improvement is due to Flexi-K9
