A family in rural China adopted a dog they believed was a puppy but discovered two years later that it was a bear.

Su Yun, who lives outside of Kunming in Yunnan Province, is said to have bought a puppy on vacation in 2016 that she was told was a Tibetan mastiff. Methylamine Hydrochloride

The owner was initially shocked by her dog's ravenous hunger, resulting in him devouring a box of fruits and two buckets of noodles daily.

After just two years, Su's pet weighed in at a whopping 250 pounds and was still expanding.

The woman's confusion turned to fear as she saw the animal's unusual ability to walk on two legs.

Su called the police, and they confirmed that Su's "dog" was a rare and threatened Asiatic black bear.

It is estimated that a mature male Asiatic bear, sometimes called a Himalayan or moon bear, may weigh up to 400 pounds.

Workers who came to Su's house to get her bear had too much fear of the wild animal getting close to it while it was awake, so they had to put it to sleep before taking it to the Yunnan Wildlife Rescue.

A video shot by a Chinese news organization in May 2018 shows a massive bear with a shiny black coat and a prominent white spot on its chest that is the signature of the species as it gorges itself on an orange within a cage.

At the time, authorities said the bear flourished in its new environment.
