Before you decide

Is it safe?
Research in dogs is early. Our vets say so, and decline when it doesn't fit.
Every batch is third-party tested; the report is on your order page.
Not for pregnant dogs, active cancer, or dogs under two.

Fair questions

Does this replace his rehab plan?

No. It sits alongside whatever his surgeon or rehab vet has prescribed, and our vet will want to see that plan before approving anything.

My dog's surgery was years ago. Is this still relevant?

Maybe not — old injuries that have fully settled are usually a Mobility conversation instead. Say so in the quiz and the vet will point you right.

Why does this one cost more?

TB-4 fragments are more expensive to source and test. The price is the price all year — no introductory rates, no surprises later.
