[C C Kent]

Your puppy needs to see you as his Master, the giver of all things good. Don't be afraid to limit his freedom, crate training is good for him as long as you establish a routine geared at potty training and stick to it. If he won't come when called don't let him off the lead until he does. Use a longer lead and treats to let him get further away, when you call him if he doesn't come you just use the lead to bring him in. If he ever wins a battle of the will you have lost...you can never lose. Keep training sessions short and try to make them fun. If he's never out of your sight he can't go in the floor. At least twice a day place him on his back in the floor and put your weight down on him until he can't move...hold him in this position and soothe him with your voice until he relaxes. After several days he will understand that you can dominate him at will....that makes you the top dog...now you have his respect. Never hurt him, just let him know you are the boss, the benevolent dictator. Once he sees you as the boss you must teach him how to please you, it will be his consuming purpose in life to make you happy. He will still destroy things, he's a puppy, just focus his destruction on things you can do without. Too much freedom is the worst thing you can do to a puppy, freedom must be earned or it will be detrimental to the eventual goal of a well behaved companion.

Stay focused on your goal and remember that a year of consistent structure will give you a lifetime of good behavior.
