My son is a paratrooper in the 82n Airborne. While deployed to Afhganistan he spent a number of months at firebase Bruin. This short video was put together by one of the soldiers he was with. I took the liberty of adding a few comments and fixing the music.
This video deals with how important it is to establish pack structure with the family pet. It demonstrates how aggressive even small puppies can be when they establish rank within their litter (family pack)
