It's very rare for people to have a puppy that's born obedient and well-trained. Like kids, the proper care, training, and education are required to mold your puppy into a disciplined pet.
If you truly see your pet as a part of the family, you should show it by dedicating almost the same amount of time to his training the way you do with your own children's education.
Always make dog training as fun as possible for both you and your dog. If either of you aren't having any fun, there's little chance for the lesson to be firmly imprinted on your pet's mind.
Stick to one lesson at a time. Dogs are intelligent creatures, yes, but they aren't able to multi-task the way people do. Repeat your training session with your dog as often as possible until the behavioral problem he has is completely squashed out of his system.
When he has successfully learned his lesson, reward him with a special treat and time to relax both his body and mind. Give him enough time to enjoy vacation from training school before moving on to the next lesson.
On correcting behavioral problems through commands, make sure that you use one-word-orders as much as possible. Never have two or more commands for just one action unless you can speak dog lingo! If you want him to sit, stick with the command "sit" rather than using "sit down" or "down" alternately.
Lastly, do understand that giving a firm command is entirely different from a loud command. Loudness is equivalent to anger in a dog's mind, and you don't want your dog to think you're angry at him, do you?
There are more things for you and your pet to learn about each other, and just as long as both of you enjoy a beautiful relationship, your dog won't mind so much if you try to polish his manners once in a while.
