Navy officer Allen Parton suffered a serious head injury while on duty in the Gulf War. It left him in a wheelchair, unable to talk, and he lost half of his life's memories. He couldn't remember his children's first steps, their first days at school, and their being born. Allen didn't even recognize his children. And he lost the ability to feel any emotion. He had two attempts at killing himself in the process of recovery.
But all changed when coming across a dog named Endal, who failed his training to be an assistance dog and needed a home. Endal saw something on the floor by Allen's wheelchair, ran across the training centre, picked it up and put it in Allen's lap. He wanted a treat, a reward, praise, anything, but he got no reaction. Then he ran over to the mock-up supermarket, took a tin off the shelf, put it in Allen's lap. Surprisingly, thatmade Allen's brain switch on and he smiled for the first time in a long time. And it was the start of their relationship.
Endal became his 24-hour companion, helping with every practical aspect of his life.
Then one night, which showed the dog's devotion, Allen and Endal were both hit by a car. Although Allen had been knocked unconscious out of the wheelchair and Endal had been hurt by the vehicle as well, he got up, pulled Allen into the recovery position, and he pulled out the blanket from under Allen's wheelchair and covered him with it.
Legs bleeding, he ran to a nearby hotel and sounded the alarm. Before that, he found Allen's mobile phone in the dark, and he brought it to his face.
And for what he did to his owner he won the Victoria Cross Award.
The dog saved Allen's life, his marriage, and brought him back to his children.
