In my never ending quest to keep my puppy entertained (read: out of trouble) I try to come up with things for him to do that force him to think.  So he has Kong toys and toys that dispense treats when he rolls them around.

Our latest game is a treasure hunt. I close Bentley up in my room (which he protests most strenuously) and then I go around the house hiding treats.  Then I let him loose to go find them!  He’s got a great nose, so he can usually sniff out the first few very quickly.  And it is interesting to watch him follow the scent trail I left while looking for them.  It’s a fun and rewarding game for him and gets him using his brain as well as using his nose!
