A cold-hearted dog owner poured water over his poor pooch and left it to die outside in Yakutsk, Russia — the coldest city in the world, according to a report.

A disturbing video posted on Monday shows the helpless 1-year-old female dog frozen to the floor of her outside kennel, one of her paws shivering.

Neighbors alerted activists of the dying animal — and responding volunteers quickly rushed her to the vet, The Siberian Times reported. The poor pup could not be saved, and was given an injection to end her misery, according to the report.

“The eyes, I will never forget them,” one volunteer told the paper. “Did you ever see a man who wanted to live but who was already dying? The dog had exactly the same eyes, understanding everything, just unable to explain.”

The activists have started a petition — signed by 10,000 people — demanding action against the unnamed owner. They have also railed against alleged police inaction in the case, and the local mayor’s policy to clean up the city by exterminating strays, the paper reported.

The animal lovers worry that cruelty to dogs could be the first step in a slippery slope to something much worse.

“It’s one thing… when your dog dies, but this man has many children,” one volunteer told the paper. “Today he lets his dog die next to his house, and tomorrow the same may happen to his children.”

A Moscow lawmaker has now taken up a case calling for the owner’s prosecution, according to the report.
