I am sure there are articles galors about what to do when you get a pup. The pup needs to be socialiazed properly, so he doesn't become a nuisance.
Walk on a leash, sit, don't move...are important commands to teach him.
Use your hands and arms to teach them commands, not just your mouth.
Keep in mind, depending on your age and theirs, they will get old, not hear you, but can still obey when they see your hands or arms.
