A heartbreaking story out of Kazakhstan: According to reports, a dog was killed while trying to save its owner from an oncoming train.

The suicidal owner had passed out on the train tracks after drinking a bottle of alcohol. According to Russian news site Ria Novosti, the man told authorities that his dog dragged him to safety. The dog wasn't able to avoid being hit.

"Upon seeing the train, the dog started pulling its owner away," said Aida Muldashevam, who investigated the incident. "When train drivers saw the dog on the rail tracks, they used the emergency brake."

Unfortunately, it was too late. The dog was killed instantly, while the owner was taken to the hospital. He had two broken ribs and an injury to his shoulder.

Dogs have a well-deserved reputation for loyalty. At a funeral for a Navy SEAL who died in Afghanistan in 2011, dog Hawkeye lay by the casket during the memorial service. And in a small village in China last year, a dog remained at its owner's grave for weeks. When villagers took the dog back to town, the dog returned to the grave. Villagers eventually decided to build the dog a kennel near its departed friend.
