Mastering basic obedience commands is a vital part of being a responsible dog owner.  These basic commands make navigating the relationship between animal and owner much easier and keep both you and your pet safe in emergency situations.  
From an outsider's perspective, basic training can look either very simple or extremely difficult.  Recognize that training can take a lot of work.  Also recognize any dog can learn at least the most basic and necessary commands.  Dog owners occasionally run into road blocks when training, don't become frustrated.  Seeking assistance from a professional trainer benefits first-time owners or individuals struggling with teaching commands or correcting problem behaviors.  Don't ever hesitate to ask for help!    
Training takes a lot of time and patience, even if you aren't trying any complicated or 'fancy' tricks.  The responsibility of pet ownership includes properly training and socializing your animal.  Before considering adopting an animal, please take into account how much time you will need to dedicate to making sure you have a happy, healthy, well-socialized and well-trained animal.
Finally, dog ownership and even training should be fun!  Don't be too serious and make sure both you and your pet have a good time so you will look forward to future sessions!
