Whelp Box - Safe Zone

About 3-4 weeks old, the puppies start getting pushy and their Dam starts the process of teaching pack manners (weaning begins). I follow suit by teaching manners for the "Safe Zone". Only non-active pups are acknowledged and protected in my lap from the rowdies. This is the start of declaring the whelp box as the sleep only place, no jumping/climbing on me, etc.
