This is what we used on our busy busy working Border Collie for his bad teeth. We fed raw, but he still gets buildup. He is too busy to bother with recreational bones. He loves these, though. At the time $36 a month was a small price to pay to avoid gum infections, dental procedures, etc. Since the price of all that has about doubled, this is still a heck of a deal! ;) -- Rebecca Shouse
