French Bulldog (details)
We don't need our dogs to be fierce, because that's not likable, but they also can't be a dog that's obedient to anyone.
When training, you also need to invite friends you are familiar with but the dog does not know to help.
Of course, when training, you need to find a few more friends and repeat the training, otherwise the dog will only think that he can't follow that person, and the others are fine. This is not acceptable.
This training is very important for dogs. Otherwise, if the dog sees anyone and follows him, it is likely to encounter some unexpected situations. This kind of dog is the most likely to become the target of some unscrupulous traders, so we must train it well.
