Merrick's flossies are great! They are just swirled bully sticks. They help clean dog's teeth and are safer to digest then most chews like rawhides. My little boy will not put these down! As for the Greenies, I have not heard anything about them or tried them at all just because I know they are recommended for ages 6 months and over, and I have a 3 month old.
