Do you think it's true that if movement is good, conformation must also be good? It depends on the balance if that is good the dog can move well even though it's construction may not be as required by the standard, in other words it may be too tall, too long, incorrect ribs, elbows in the wrong place, neck too short and so on but if the over all construction is balanced the dog may move well even if it lacks type.
The importance of movement is in direct relation to the work the breed originally did, a toy dog should be able to move well enough for it's own comfort but a working dog must show movement that makes it fit for the job it was developed for.
The laying on of hands and the checking of movement should go hand in hand, if the dog is well constructed you expect it to move well but if you find a fault in the construction you will watch the movement to see how that is effected.
