This chilling footage is from a Chicago Police Department body-worn camera. The Sergeant wearing the camera and assisting officers rescued a 33-year-old man at 1:05 p.m. on Sunday who had jumped into Lake Michigan to save his dog.

The man, who wishes to remain anonymous, was walking his dog near Foster Beach, when the nine-month-old adopted dog darted towards the ice on the lake and ended up in the water.

The owner jumped into the lake to rescue the American Eskimo mix, named Pika. He was able to save the 19-pound dog but was unable to get out of the lake due to large ice walls that formed along the water's edge.

"He started yelling, 'help me, help me,'" CPD Officer Miguel Del Toro said during a press conference. "We ended up crawling on our knees over the ice ridge to get to him."

In a written statement the man said, "I have no doubt that I would have died without help, I am forever grateful to them," he wrote. "Pika and I are both fully recovered and in debt to our gracious and heroic first responders."

Both the man and the dog are doing well.
