SportDOG Clear Competition Mega Whistle

I carry the whistle with me around my neck. I alow her to run free with other dogs through a wooded area. When I am ready to retrieve her I blow a couple of times and she returns immediately.

The whistle gets the attention of my border collie when she is in a full run. She will stop and come back when she hears the whistle. I use the whistle in a 20 acre feild and this works when she is on the other side of the feild. Aunt LuLu
