A two-month-old puppy gets more aggressive and aggressive

A two-month-old puppy gets bigger and more aggressive. This is usually because the owner does not pay attention to clarify its class status. It feels that its status is higher than yours and that it is the leader. Therefore, It becomes bigger and more fierce when you hit it. It is necessary to make appropriate training changes, such as punishing the dog when it is disobedient, deliberately ignoring it, leaving it alone for a period of time, and then using food for some simple obedience training after it becomes more well-behaved.
