I'm quite a newbie myself as I haven't yet shown or even thought about it until recently. At ringcraft, we just put the dogs through their paces as though we were in the show ring. We put them on a small table and place them in position, often called 'stacked', then the person taking the class comes and looks at the dogs teeth and feels them all over to check muscle tone etc, feels the coat and generally checks the overall condition of the dog. Once that is done, we do a show walk which is generally in the shape of a triangle, at all times keeping the dog between the judge and the handler so that the gait and movement can me checked. We just do this continually, joining the back of the line after our turn. Any recommendations are given at each turn, such as walk faster, hold the show lead more taught, don't look down at the dog etc etc. It's a bit repetitive but gets you and the dog into the correct mode and position for showing.
