For future consideration:

As NACSW continues to grow, we continue to work to broaden the parameters for appropriate trial locations.  One challenge with some locations is the proximity of search areas to the parking area or bathrooms and the audibility concerns this presents.  Especially at NW3 or Elite where the number of hides is unknown and hearing competitors call Alerts may give other competitors inadvertent information.  Additionally, the possibility of a judge asking ‘where’ can cause audibility concerns as well.  There are some teams competing whose trained alert behavior is a bark.  This alert behavior may limit the trial locations we can approve moving forward.  We have no intention of penalizing those teams already competing with this behavior, however as we look to the future we will be looking closely at adding a rule to discourage trained audible alerts.  We wanted to make our participants aware so that those starting with new dogs may take this into account when making training decisions about trained alert behaviors.  We do want to emphasize that we are not concerned about dogs that bark in excitement during a search, just those that have a specific trained alert behavior of a bark.


The numbering system for identifying the edition of the NACSW rule book is as follows:

  • If there are significant changes to trial structure, scoring, or title definitions, then a new numbered edition of the rulebook will be issued (i.e. 5.0, 6.0, 7.0).
  • If there are only small language changes, typos, changes to the guidelines, wording clarifications, or other changes that do not affect titling or training the version number will be added under the existing version (i.e. 6.1, 6.2, 6.3).
  • Major revisions to the rule book especially those that affect training will be announced with consideration for the time allotment for training adjustments.  Other revisions will be published no later than the trial entry open date.
