Ken Wyrsch was stationed at an army base in Iraq when he first met Ollie, a stray puppy that the soldiers had started taking care of. Ken and Ollie instantly became best friends, and the puppy was an important part of the soldier's life on the base.
Ollie grew bigger as time passed, but he and Ken were always inseparable between missions. "He was there when we left our missions, he was there when we got back," says Ken.
One month later, after getting some very generous donations, the pair were reunited in the USA.
