Police tried to resuscitate the unconscious victim before transporting him to Ingalls Hospital in Harvey.
Witness Dustin Neuliep of Chicago Heights says he called 911 after seeing two dogs wandering around -- one on a trail and one on the ice. He then spotted the dogs' leashes and a cane on the ice
Neuliep says he was able to get the dog to leave the ice. Both of the victim's dogs were taken by firefighters.
