How did a wolf become a dog?
There was a show on TV, Wolf training. At the beginning, closed up like a dog, fed, and then trained. But wolves have little interest in food rewards. Later the trainer decided to starve the wolf for a few days. But wolves are still not very cooperative during training. Later, the trainer discovered that wolves like to hide part of what they eat and eat when they are hungry. So after cleaning up the wolf dormitory, the wolf will continue to be hungry. Retraining with food rewards is very effective, and the wolves are also very cooperative. I think this program is of great reference value. How a wolf turns into a dog is a food problem. I'm really hungry if I'm not obedient!
