Separation anxiety is predominantly the cause of most canine behavioral problems in both adult dogs and puppies. And many problems such as chewing, excessive barking or digging up your back yard happen from a lack of communication between you and your pooch. Basically your dog does not know what you expect of him.
Using some effective obedience training techniques at the developmental stage of your dog's life, is the best way to prevent any problems from occurring, now or in the future.
It's important to have taught your dog that you are the Pack leader and that when you set the boundaries of acceptable and unacceptable behavior you hold fast to them. Make it easy for your dog to understand the boundaries by being consistent.

Do not think that your dog is out to upset you or make you angry when he starts playing up this is not the case, most of the time there will be a trigger that sets the bad behavior off, and as the pack leader it is imperative you find out what that trigger is to be able to solve the problem.
Are you rewarding your dog inappropriately, there by rewarding him for the behavior problem you are trying to eradicate? For example someone walks by your house and your dog spots this person and start barking excessively, your pooch is warning the person that this is his domain and that person should stay away. But for you the owner having to listen to his excessive barking, it just gets very annoying, so do you call him away from the window telling him "Be quiet" or even physically remove him from the window and then rub his neck to help calm him down? If you do, then you are rewarding him for his actions, he is then going to repeat said actions because he gets a reward.
