Obedience training is definitely the most important aspect of owning a dog. It helps establish the right relationship between owner and dog. In order to "balance the scales" in the relationship between dog and owner, there needs to be a clear understanding as to who is the chief and who is the Indian. An owner needs to use obedience training to teach the dog that the owner is not only important to the relationship but also the leader. The dog also needs to be taught that he is the follower in the relationship.
As a dog owner, you need to understand that dogs are creatures of habit. Our job here is to teach the dog to have the "habits" we want them to have.
