A group of four young Russian men who stopped by a frozen river near the Russian town of Podolsk (Moscow Region) to fix their car heard the howling of an old stray dog struggling to get out of the water. Not hesitating, one of them pulled off his clothes and jumped into the ice-cold water. You can see on the video how he forces his way through the ice in order to get to the dog. The man whose name is Ivan is a native of Yoshkar-Ola (Mari El Republic, Russia) and lives in the nearby village of Shishkino where he works at a local sawmill. Apparently, the young man suffers from a heart condition - still, he didn't hesitate to put his life at risk in order to save the animal. The young man decided to adopt the dog whom he named Rex.
