bond: In 2007, a US Marine in Iraq befriended a
 stray desert dog called Nubs. After someone
 stabbed the dog with a screwdriver, the
 marine nursed him back to health, developing
 such a bond that when the unit left, Nubs
 picked up the scent and walked 70 miles
 through Iraqi desert war zone to be with him.
 it's enough to make a grown man cry, and that's ok
it’s so beautiful
