This vet-approved product has helped me manage my dog's arthritis and enabled me to take him off Previcox, which is a drug. Cosequin is all natural; it is pain saving: it brought my pomeranian (and me) relief. After one year on Cosequin, my dog is still walking and climbing stairs without limping. I highly recommend Cosequin. I also give my dog microlactin (dairy based) and sodium ascorbate for managing pain, but the Cosequin seems to do the bulk of the work.
