In my opinion, you have no business even having a dog. You should have thought about your "two small children" and taken that into huge consideration before even getting a dog. If you want a good dog, then you must be willing to do the things needed to obtain that goal. Dogs are very personalable animals and don't deserve to stay outside and get the crumbs of attention you decide to give them when you feel like it. To them, that's punishment. Dogs are living, breathing creatures, not some piece of property you can dispose of when you see fit. And for goodness sake, find a good home for her and forget selling her. If you really cared for her, money would be the last thing on your mind.
