Below is a slideshow of Rudy and Wrangler working out in an open area as opposed to a round pen or arena. These pictures were taken on 14 Feb 2009. These pictures were taken after Rudy spent some time working Wrangler with the bag on the ground. As you can see in the beginning Wrangler kept his distance from the bag but gradually came closer and closer.

Below is a video clip showing the progress Wrangler and his owner have made. This video was recorded on 1 May 2009.
