Tyson was just a baby when he was captured by the hunters who killed his mom. Ever since then, he's grown up in a small, dirty cage. It's believed that Tyson was only allowed out of his cage for something terrible — a practice called "bear baiting," which still goes on even though it's illegal.
"Hunting dogs are trained to attack bears in a practice known as ‘bear baiting,’" Carsten Hertwig, bear expert at Four Paws, said in a release. Footage from Four Paws shows what this heartbreaking practice looks like: Bears are chained up and terrified while hunting dogs circle them. The bears are often weak and starved and sometimes have their claws painfully removed so they can't defend themselves, according to Four Paws.
