 Family thinks they adopted a rare dog, two years later they realize it's not a dog at all. Sun Yoon and her family needed to shake their lives up. The day today in the family's house was normal, each new day similar to the one before, and the quickest way to get some excitement was to adopt a beautiful pup from a street vendor. But as their new pup grew, the family realized they'd brought in way more than they bargained for and soon authorities were asking them questions they couldn't answer. Sun Yoon first decided to break the chains of monotony with a family vacation in 2016. Soo Yoon and her kin packed and prepared for months, ready to see a bit more of their home country, China. While on their trip, they ran into a street vendor with an interesting collection of merchandise, dogs. Sun Yoon's kids immediately fell in love with one of his pooches, a sweet, adorable, fluffy black puppy. The vendor had high praise for the dog. The vendor told them it was a Tibetan mastiff, an intelligent and loyal dog you couldn't easily get your hands on. This was a fascinating development for Sun Yoon she couldn't pass on a dog like this, could she? Soo Yoon knew her kids were aching for a pet, and she couldn't say no to that black, furry face. She returned home to Kunming with a new family member they named the Puffball Little Black, and they couldn't have been happier. But some problems were about to begin. Little Black wasn't going to stay little for long, as the Tibetan mastiff is one of the world's largest and rarest dog breeds. Those big boys can weigh up to a whopping 170 pounds. Woof! This was apparent in Sun Yoon's smaller home. Just as the enigmatic man from the street warned Soo Yoon, Little Black grew fast. He roamed their small home, gobbling whatever he could get his paws on, to the point where something seemed wrong. All Little Black did was eat. Soo Yoon said he would eat a box of fruits and two buckets of noodles every day. And after just a year of feeding Little Black, Soo Yoon noticed a massive dent in her bank account. The family was on edge with how fast Little Black was growing, and the situation became more dire once their not-so-little pup turned two years old and weighed a mind-boggling 250 pounds. Sun Yoon began to doubt this was a mastiff. She was unsure of what four-legged creature she brought into their home, until she witnessed Little Black standing on his hind legs in the middle of the kitchen. Her stomach sank. It was at that moment that she realized the truth she'd been denying. Soo Yoon tried to ignore the enormous teeth, the rounded ears, the razor-sharp claws, but in that moment she fully knew Little Black was, in fact, a bear. Exciting as this was, it put the family's life in a lot of danger. She called the police, explaining her bizarre predicament as best as she could. The more he grew, the more like a bear he looked, said Soo Yoon. I am a little scared of bears. Experts came over to evaluate her new theory. It wasn't long before police officers and wildlife experts from the Forest Public Security Bureau showed up to check out Little Black. The furry guy turned out to be an Asiatic Black bear, a species that is currently considered endangered. Sadly, in many Asian countries, they're illegally traded and milked for their bile, according to National Geographic. The yellow liquid is sold with false claims it can treat everything from cancer to a hangover. Authorities rushed over. When officials arrived at Soo Yoon's home to fetch Little Black, they were shocked at his size, as he stood on his hind legs to be about a meter tall. Understandably, Little Black was sedated prior to transportation, just in case he acted out in fear. Little Black was taken to the Yunnan Wildlife Rescue Center, where he'd likely spend the rest of his days. He'd been through a lot, arguably more than Soo Yoon and her family, who were clearly oblivious. Wild animals are just that, wild, and should never be kept as pets. Soo Yoon escaped jail time for illegally housing an endangered, not to mention dangerous, wild animal. It was likely due to her cooperation with the police, and the fact that she seemed so genuinely unaware, but Lynn Cuny, founder and president of San Antonio's Wildlife Rescue and Rehabilitation, wasn't buying it. You never think you're hearing a dog or a puppy when you hear a bear, Lynn said. My first reaction to this is that there's something more going on here than just an honest mistake. This should never happen. Too harsh. Maybe not. According to Lynn, it's typically easy to tell the difference between young wild animals and domesticated pets. In the presence of humans in foreign environments, wild animals will be more frightened and anxious than domesticated animals. Lynn Cuny believes that the issue of wild animals being removed from their home circles back to how society treats, views, and, in more vile cases, abuses animals. If this happened to a person, everybody would be up in arms, Lynn exclaimed. Well, she's not wrong. Though what happened with little black was unsettling, tragic even, this kind of mix-up happens more than you'd think. It's been estimated that there are likely 1-2 million animal species in the world, and some of them happen to look very much alike. Estonian dam workers Rando, Robin, and Erky would learn this the hard way.
