A Massachusetts police officer heroically dove into a murky lake to rescue a Chihuahua from eight feet below, in a completely sunken truck. The little dog was not breathing, but after pulling him from the water, Officer David Harriman also revived him.

Debra Titus, 59, narrowly escaped with her own life when her pickup truck plunged into a lake on Saturday. One dog, Stitch, was able to swim out with her, but her little Chihuahua, Moochie, was trapped.

She called the Carver Police Department and frantically waited, feeling totally helpless. The right officer responded to the call. David Harriman is described as an “avid dog lover.” He has an eight-month-old English bulldog named Jax and says he’d “do anything I could for him.”

“We showed up at the water and saw the vehicle was submerged,” Harriman told the Boston Herald. “We were told a dog was still in it, so I did what I felt I should do – go in and get the dog.”

He quickly removed his gun belt and shoes and dove in.
