Training you dog is very important, you will find that a trained dog will be welcome in other peoples homes.  You will be able to have family and friends over with out having to put your dog away in a room by it’s self, for fear that it might pee on someone or bite someone.  A trained dog will not run out in front of traffic and will come when you call them.  Having a well behaved dog will benefit you and the dog in the end. Obedience is a plus and your company will appreciate your efforts in training your dog.
