Training dog obedience requires establishing a sense of leadership

When eating, you can prepare the dog’s food first and place it in front of them, but they are not allowed to eat. If you can't control your dog well, put them in a cage or on a leash and put food where they can see it but not eat it.
At this time, you can eat your food in front of them. No matter how they protest, they must be ignored and must not compromise. Wait until you have finished eating before letting them eat. In the dog world, the leader eats first, and other members must obey and take orders from the leader.

To train a dog’s obedience, you must conquer it with your eyes

When you are sure that the dog will not attack you, you can let it lie on the ground with its legs in the air, and then put your hands on its chest , suppress them, discharge them with serious eyes. If at this time their ears are back, their tails are tucked, and they avoid your serious gaze and do not dare to look at you, it means that the dog has obeyed you. Next, reward it with gentle eyes, words and strokes, so that the dog understands that as long as it obeys, it will be rewarded by the owner.

Training dog obedience requires appropriate cold treatment

When a dog does not accept you or is aggressive towards you, the best way is to ignore it. Dogs can't stand your lack of attention. You can also use this method when its behavior dissatisfies you and you need to punish it.
The specific method is to limit it to an independent space, not to see it, not to think about it, and to treat it as if it does not exist at all.
