We have two of the original kongs...just buy the solid kong treats in peanut butter or liver...my baby absolutely looooooooves to chew on those toys until she breaks the treat inside and gets it out. I also bought the kong bone....also one of her favorite toys...I stick half a little bone treat in one end and the other half in the other side.
These are the beeeeest things in the world if you work and have to leave your little ones at home alone.
