【简答题】
Dogs are social animals and they will behave like wild animals without proper training. They destroy your house and belongings, bark too often, fight other dogs and even hurt you. Nearly all behavior problems are perfectly normal dog activities that take place at the wrong time or place or for the wrong things. The key to preventing or treating behavior problem 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 obedience training. Obedience training doesn't solve all behavior problems, but it is the foundation for solving just about any problem. Training helps the communication between you and your dog, which 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 dogs obeys a simple request of “come here, sit”, it is showing obedience and respect for you. Sometimes you can use extreme measures to establish yourself as top dog or leader of the dog pack. You can teach your dog to show submission to you. Most dogs love performing tricks for you pleasantly if they accept that you are in charge. Training should be fun and rewarding for you and your dog. It can be helpful for your relationship and make it more enjoyable to live with your dog. A well-training dog is more confident and is allowed a greater amount of freedom than an untrained animal.
