The Kong Dog Biscuit Ball is a twist on the standard Kong toy.  Check out the Kong post for a review of that one.  Anyway, we like this toy because it is much easier to stuff.  You just cram dog biscuits into the openings.  It’s not all that hard for the dogs to get the biscuits out, but it takes a little time.  There is the added benefit of increasing the chew time on the biscuits — they have to chew instead of just swallowing them whole.  The ball itself is sturdy and holds up well.  The Kong Dog Biscuit Ball is one tough dog chew toy.
