ANWI™ means Associate Nose Work Instructor, as recognized by the National Association of Canine Scent Work, LLC®, or NACSW™. This past weekend I attended days 2 - 4 of 7 days of seminars, to become a CNWI™ (Certified Nose Work Instructor).
Nose Work isn't plastic surgery; it is a game or a sport (depending on your level of involvement) where dogs find defined scents in a variety of environments.
