Sully was named after Capt. Chesley Sullenberger, who landed his plane on the Hudson River, saving the lives of everyone on board.

As CBS News Chip Reid reports, service dogs support veterans and first responders with daily tasks and help mitigate the symptoms of post-traumatic stress disorder. They also provide comfort to vets in need.

"He's going to make people smile every day. He has got this fantastic trot, and his ears just flap about, and you just can't not smile," said his trainer, Valerie Cramer.

It costs $50,000 to train one service dog, but the veterans don't pay a penny. It's all paid by America's VetDogs.
