This is the touch-and-go moment a lost dog is rescued by a team of thick-skinned firemen after getting trapped in the middle of a frozen river. Video footage shows emergency workers swimming out to Cooper the Goldendoodle as he sits shivering  on a sheet of ice on the Charles River in Wellesley, Massachusetts. He is then grabbed by his collar and hauled back to shore in a sleigh before being wrapped up warm in a blanket. At the end of the clip Cooper's owner, Jared Bartels, is seen bounding up to give the eight-year-old pooch a big hug. 'Thank you, guys, I appreciate it,' the father-of-three tells the animal's rescuers. The recovery mission took place on Sunday morning with temperatures around freezing. It's not known how long Cooper was on the ice for but he went missing around 4pm on Saturday after he got spooked and ran off during a walk.
