One of the best things you can do for your dog and yourself is to obedience train (驯服) it. Obedience training doesn't solve all behavior. problems, but it is the foundation for solving just about any problem. Training opens up a line of communication between you and your dog.

Training should be fun and rewarding for you and your dog. It can enrich your relationship and make living together more enjoyable. A well trained dog is more confident and can more safely be allowed a greater amount of freedom than an untrained animal.

B．worsen in modern society
C．occur when they go wild
