Hide and Seek

How many of you play hide and seek with your dog?  It is a great game to firm up their recall.  The kids can play it with the dog.  Hide somewhere in the house and then call your dog.  When he gets to you praise him and let him know he is the smartest dog in the world.  This makes the recall fun for both of you instead of frustrating when you are "formally" training and the dog ignores you.  If training isn't fun for you and your dog, you're not doing it right.
