These are just okay and the one Nylabone Chew toy I will most likely NOT purchase again.  Although my dogs loved these, as they chew on them they get very sharp edges.  And when you are walking through the house barefoot in the dark and step on one...IT HURTS!!  Also, these are small so don't buy them for your big dogs.  I bought one for my 20lb miniature poodle and it was just the right size for him.
