However, your dog is only one month old, and it is the time when he explores the world and is most curious. Don't be afraid that it is too lively, which shows that it is healthy and a good thing. If one day it lay uncharacteristically quietly on one side and didn't want to move, it would be worrying whether it was ill. Because dogs have strong endurance, if they are not really uncomfortable, they will still pretend to play as if nothing has happened.
You have to teach him to obey your discipline, and you have overcome your fear of dogs. First of all, you can't show your fear of him. As soon as he makes a noise, you cry in panic. Dogs can see your reaction. It'll be fun. Keep teasing you. You see, those people who are chased by dogs are running and barking, and the dogs are desperately chasing them.
When you speak to it and give orders, you should be as calm, strict, concise and decisive as strict father. Is to look superior and comfortable. If it can't be quiet, you can yell and hit it on the head. Be sure to add sounds and actions. You can also slap it hard and knock on the table to threaten it. Be temperate when you are close, and don't spoil it too much. Wearing a leash when going out can help it know who is the owner. Keep it safe.
You can get imported quadruple vaccine in 3 months. It's best not to let him go out to contact with other dogs before, so as not to spread diseases.
When its teeth grow, its roots itch very much. You can give it summer slippers to bite. In my experience, it will be completely better after 3 or 4 months.
