The first thing you'll need is the Premium List with the entry form. These are available from the show secretary or superintendent. These people are hired by the club to manage the show's entries, provide equipment, keep records, and much more.
Premium lists are often available on Infodog.com if MB-F, Inc. is the superintendent. Click on "Show Information" on the top left and then use the search tools to find a show to enter. If the show name is in green, MB-F is not the superintendent, but that contact information will be listed. Contact them instead to obtain the premium list. If MB-F, Inc is the superintendent, then once it's released, the Premium List list can be download. Look for it on the left-hand side.
When it gets closer to the event, you'll receive the Judging Schedule in the mail. This will contain when each breed is judged, lodging information, and rules. Paying attention to these important details will enable you to relax on the big day.
