This short video is of Cindy's 6 month old puppy, Endy, working whistle backs with two friends (Forrest Micke and Tim Bartlett) who trained within the same system of marker training that we do.

The two significant issues of this video are that Cindy was not present on this training weekend. She was on a trip, so Endy is being handled by two people she doesn't know. Endy is being whistle backed from a situation where she is highly distracted, she will be playing tug with either Forrest or Tim and whistled back by the other.
