Awesome dogs last night! I had a house full of people and after their initial inspection of guests as they arrived, they went to their respective areas and hung out. There was the occasional check in but other than that, you wouldn't have even known there were dogs in the house.
The time spent on good manners training pays off in a multitude of ways. 
When you are working with your dog, think of the behaviour you would like in the long run and do your best to reinforce when you see it. Include some short training sessions scattered throughout the day (3-5 repetitions) . Be patient and consistent and watch the behaviour develop.
