Okay....I just had to add another photo of this puppy.  I really like him and when I brought him in it didn't take Mom long to start him playing.  I had a great time watching the interaction between them.  Bubbles is an awesome mother and takes her job seriously.  She plays rough but gentle at the same time.  Allowing the pup to realize that it is play and to join in the game.  If you watch any animal planet on the wolves or coyote behavior it is the same.  Teaching their pup how to defend itself when the need arises.
