Rally is sometimes thought of as a combination of classic obedience and agility.  It requires constant communication between dog and owner.  Each rally course is designed differently, and this makes it a wonderfully stimulating exercise for both handler and dog.  The owner may use voice commands, hand signals and body movements to communicate to their dog.  Praise and petting is also allowed.  It is a fast paced sport with a four minute time limit to complete the course.
