I stopped at GoodWill today and got all 4 dogs new/used stuffies.  Reyna (alpha dog) got to pick first,  she choose and ran off.  The other 3 I made stand in the middle of the room and teased them a little and then threw the stuffies in the air. Each one grabbed one and then tried to grab another one, which was already in a dog mouth.  So there is major tug o war here. Gonna try and get pictures.  Happy Happy Puppies!
