Tip of the Week
I try not to sound like a self-help motivational speaker too often. However, there are times when the key to success is visualizing what you want to accomplish and then making it happen. Ultimately you have to care as much at that particular moment about what you wish to accomplish as your dog cares about doing the opposite. 
Remember that your dog does not have as many distractions in her life as you have. Your dog does not read, watch TV, surf the internet, have work or school, or have friends and family to keep tabs on.  All their energy and focus is devoted into chewing, digging, jumping up, barging out of an open door, or any other problem behavior.  If you are only partially involved in attempting to stop these problem behaviors, but your pet is all in, then you will likely lose the initiative and ultimately the battle.
As I have written on this page previously that our dogs live in a human world, and there is nothing that my dogs enjoy that does not come from me. I am the one who buys and serves the food, throws the ball/frisbee, takes them for walks, shares love and affection, and opens doors to go out and potty.  At the moment you are feeding your dog you have to care as much about your pet staying back and showing polite manners as your dog cares about charging forward. You must care as much about your pet staying inside when the door opens as your pooch cares about shooting out.
Even if you use the right methods and techniques, but are not willing to see things through, simply because you are not invested as much as your pet, then you will only be partially successful at best.
