There are many reasons for it to bark:

1. It doesn’t like the smell of you;

2. Your contact with the dog is incorrect, causing it to misunderstand that you are a threat to it.
In fact, no matter what kind of dog they are, as long as you can master the method of contact with them, you can prevent them from barking. For example, if you meet a cute dog on the road and you can’t help but want to pet it, you can Keep a certain distance from it first, don't scare it, squat down slowly, and slowly stretch out your palm (stretch from bottom to top with the palm facing up) to let the dog get familiar with your scent. When you see it wagging its tail, it proves that it likes you and accepts you. You can stroke its head and say some complimentary words to it (for example, you are so beautiful, you are so good, etc.).

However, there are still some taboos for dogs:

1. Do not make any sudden movements or shout in front of dogs (especially other people’s dogs);
2. If it is someone else’s dog, remember not to touch their butt and tail;
3. Don’t let the dog feel that you are condescending, and do not interact with them When you are together, you should maintain a squatting or sitting posture as much as possible, and do not let them feel distant.
4. When you are at a friend’s house with a dog (be more careful if it is your first time there), do not walk around or hang around, and do not take the dog’s toys or food. . After all, today’s pet dogs still have the habit of protecting their families and their owners.
5. No matter where the dog is, if you find that it does not shake its head and tail at you, then you should be careful. It may be in a bad mood, or your actions may have made it unhappy. , it may be about to attack you.
You can specifically train your dog to recognize strangers

1. Before training, you need to find someone unknown to your dog to act as an assistant. The safer thing is the person who knows the dog well. In this way, it is easier to avoid accidents. If you really can't find an expert, try to find a friend who is smarter.

2. If your dog doesn’t like to question “unknown people”, you can take it for a walk somewhere farther away. Put a collar and warm clothes on your little one, and don't use a chain that chokes the neck. Pretend you meet your friend across the street, slovenly wearing a hat and collar, leaning behind a tree. As you lead your dog closer, he watches you furtively from behind the tree. If you are willing to exaggerate, he even wears various ghost masks, which completely cover his face and only reveal his two sneaky eyes. He had to walk very quietly, and even when he stood he looked different from ordinary people.

3. Observe the dog's reaction, and while it is hitting the "suspicious stranger" in front of you, whisper to it: "Who is that? Be careful of him. Who is that? Be careful of him!" "Your voice is full of suspicion.. If the dog barks loudly, your friend should quickly hide and you should praise the little guy for saving your life and property.

4. After the above actions are completed. The day's training ends well with the dog, your friend, and you! By the way, during this process, it is best to let your friend act a little exaggerated: immediately show the urgency to run away, which will make some timid dogs feel more victorious.

5. If the effect of the first test is not obvious, your assistant should look for and hide behind the tree again, waiting for Yu and the little guy to "encounter" again. The second time you go out for a walk, the process is the same as the first time.

6. The ideal effect is that after several trainings, the little guy will scream at the mysterious stranger (what are you holding an umbrella in broad daylight?) until the other person disappears from sight. Each time the training time increases, the dog becomes more and more courageous and confident, and even full of pride and pride, because it begins to understand that the little gangster is so afraid of it, and it barks louder and louder.

7. After achieving such results, you can ask your assistant to raise your hands in the next training session and come out from behind the tree pitifully. The purpose of this is to send a message to the little guy: the other party has raised its hands, it has surrendered to you, and if a stranger follows my master in the future, I will do the same!
