Dogs are social animals and without proper training, they will behave like wild animals. They will spoil

your house, destroy your belongings, bark excessively (过分地), fight other dogs and even bite you.

Nearly all behavior problems are perfectly normal dog activities that occur at the wrong time or place or

are directed at the wrong thing. The key to preventing or treating behavior problems is learning to teach

the dog to redirect its normal behavior to outlets that are acceptable in the domestic setting.

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. Effective communication

is necessary to instruct your dog about what you want it to do.

Training is also an easy way to establish the social rank order. When your dog obeys a simple request

of "come here, and sit", it is showing obedience and respect for you. It is not necessary to establish

yourself as top dog or leader of the dog pack (群)by using extreme measures. You can teach your dog

its subordinate (从属的) role by teaching it to show submission (服从)to you. Most dogs love performing tricks for you to pleasantly accepts that you are in charge.

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.
