When Dennis, a young soldier, first met the dog at a fort in Iraq, the dog wasn't interested in making friends. The dog, who lived in the wild, had already been through a lifetime's pain and neglect. His ears had been cut off, and he had been trained as a fighting dog. Now that he was finally free of his cruel master, the dog just wanted to be left alone.
But Dennis saw something special in the dog, which he nicknamed "Nubs", because of his missing ears. It took some time, but eventually Dennis had the dog eating out of his hand. One day, when Nubs showed up with a deep wound, Dennis nursed him back to health. Soon, Dennis and Nubs were close friends.
Sadly, Dennis learned that his unit would be forced to move to a new base, and he wasn't allowed to bring Nubs along.
But two days later, a familiar face turned up at Dennis' new base. Somehow, Nubs had managed to follow the unit through the Iraqi desert on foot, all the way to their new base—70 miles away.
"God knows what he went through," Dennis said. "When he arrived, he looked like he'd just been through a war zone. "
Even though it was against military rules. Dennis, unit felt compelled to give gave the determined dog a home. They built a doghouse for Nubs, but were soon informed by the military police that Nubs would have to live elsewhere. So, Dennis decided to take Nubs home with him. The dog is currently in Jordan, and will soon be sent on a plane to San Diego, where he'll be reunited with Dennis once again.
Dennis looks forward to taking Nubs to play on the beach, feeding him dog food, and letting him bask in the sunlight.
