What many parents don't see is how the child is performing behavioral modification on the parent. I won't name names, but see situations where a parent isn't capable of being in control because the child knows how to push the buttons. And the buttons can only be pushed if you put them out there for all to manipulate.
I think everyone should have their own dog before raising a child. While all children are not created equal and the same is true for dogs (even in the same litter), it gives one a chance to make mistakes with a most forgiving and appreciative species.
Some dogs - like my Rhodesian Ridgeback - are masters at reverse training. Often in my household I am called in when Maverick decides he wants to do something and damn anyone who disagrees with him. His favorite is getting on someone's bed or on the leather couch. Dad is called. When I walk in the room, the problem is usually solved just with my appearance. My dog knows that my expectations are clear and consistent, and there are immediate consequences to blatant disobedience. When he gets testy, often all I have to do is pull my belt off, fold it in half, and start snapping it. That usually sends him scurrying into his kennel cab.
On the flip side, a Ridgeback doesn't make noise unless there's really something going on. When number 2 son is doing something stupid with the dog, I can often tell just by the sound of things at a distance. When I walk into the room, Maverick often will run up to me and start licking my arm or leg, knowing that the right thing will come of my presence. When you have your own act together, all around you sense it and respond accordingly.
One of the smarter things I did with my teenage son was to let him stay home with this new puppy for the summer - by himself. At first he was in puppy heaven. Then the reality of responsibility hit him. One day he asked me why I got such a stubborn breed. I looked at him and said "Well, he reminded me of someone I know and love." As they say, what goes around comes around.

I have found many times in my martial art teaching carreer that the best thing you can do to a pain in the ass in class is to put them in charge and let them see their own behavior thrown back at them. Responsibility kicks in faster than you can say attitude adjustment.
After 3 months of being at home alone with a responsibility, my son's room is the cleanest in the house and his grades have gone up significantly.
The moral of the story here is to get beyond treating children like you're in a constant battle with them. Give them opportunities to take on responsibility, and have them understand what it is like to set their own expectations of others.
It's also worth mentioning that when you take a dog to obedience class, the real "training" is happening with the owner and not the pet. Food for thought...
