Communication is the Key
Dogs communicate mostly through body language but face it folks, its hard to know for sure what your friend is trying to tell you all of the time. That's why its key to establish a verbal line of communication with your dog starting on the first day. All dogs no matter their age are able to learn how to verbally communicate as long as positive reinforcement is applied.
Look your best friend in the eye and speak clearly. Then motion toward what it is you are indicating and very quickly they will begin to put things together. For example: Does he want to go outside? Well then don't acknowledge his desire until he gives you that sharp bark of affirmation. Keep asking until he does so and verbally adore him but do not reward with treats, this is not a trick and you do not want your dog to think he is going to get a biscuit every time he barks. Use this basic method for everything else you need to communicate and it will clear up any misunderstandings you may be having.
It is essential that you spend time talking to your dog. He needs to hear your voice and he needs to know what you call the things in his world. At times my lab will not want to leave the backyard but using verbal communication I am able to literally ask him what it is he wants to do. Usually he wants to walk out front and survey his domain. This didnt work out so easily before he learned what "out front" actually was. Try it and be patient with your best friend, just like he is with you.
