If you plan on competing with your dog, even if you you do not plan to
be a serious competitor, you may want to purchase some some orange
cones to mark off the scoring distances when you practice. This will
give you a better idea of where the distances are that will give you a
higher score. Cones can be found at toy or sporting goods stores.
