So what do you suggests then? I'm in total agreement with the trainer here...immediately take dog outside to piddle and give reward and treat for going in correct area...hit them or yell at them you will have more problem behavior. It's not like they won't slip up or be completely trained in one session. It;s a constant thing and you learn to watch for behaviors that tell you dog needs to go outside. Our dog would go sit near the door and cry if you didn't take her out.
