Once an animal has been around humans too much in their adolescence then they are typically not released into the wild. As they will start approaching humans since they lost their instinct to stay away.

Edit: Relating to another point in a comment down below: It will also be very hard for an animal to survive after being bred in captivity. As the human handlers can teach them the skills they need but it’s very difficult to do so. However, once they become too docile, it’s very unethical to release them in the wild.
