Effective joint support

Our oldest dog Molson (7) was diagnosed with arthritis and once he started taking these, we saw a noticeable difference in his mobility!

You NEED to try this supplement

Our high energy border collie is turning eight this year and we want to make sure we are taking the best care of his joints that we can. We had been looking for a joint chew with krill and we have been really happy with PupFlex.

- Arlo

Excited for this

PupFlex+ made a big difference for my dog’s mobility. He used to show some stiffness after long walks, but after a few weeks of using these chews, he’s much more active and moves with ease.

A Game-Changer for My Dog

Love love love!

My pups love these so far! My senior dog (12) was diagnosed with arthritis and hip dysplasia a few years ago and I’m always looking for new supplements that can help! I’m also having my 5yr old dog take them. Never too early! We are loving these!!!!!

Great!
This product was truly game changing! I will say it does take some time to work, but as my oldest pup gets older he starts to get lazier and when trying this product I could tell he felt over all happier. Like he felt good. My youngest pup I couldn’t really tell a difference personality wise, but he is the trouble maker. Will buy this product again.

Great ingredients!

So far so good! I Haven’t seen any noticeable improvements in mobility or activity but I know this takes time with supplements and that by introducing these early we are going to be setting ourselves up for success later on! One dog loves them, the other isn’t so sure, but he’s super picky so maybe not the best taste tester 😆 thanks bio pup for letting us try these chews out!!R
