We have a new DVD and/or CD on whistling available. It is Welcome to Whistling with Derek Fisher. Hear and see in action Derek's clear and concise whistles, how to choose which whistles to use, the importance of variations in your whistles and better communicating through whistles. You can purchase these on our website at www.bcollies.com/videos.htm, through Derek directly, through Border Collies in Action or they will be available at Meeker and the Sheepdog Finals.
