My last order was for a very long period. I use glucosamine and chondroitin (2+2 per day) for my 42-kg dog with quadrilateral dysplasia, which we rescued from a kennel a few years ago. We’ve been using the capsules for a few months now. The dog couldn’t walk longer than 5 minutes. Now he runs, jumps, wants to take long walks, he is a happy dog. I think he feels no pain. Doesn’t take any medication. I have found the solution, in any event for now. Thanks and until the next order!
