Tim, a 6 month old Golden Retriever, loves to chase birds. Here he is using every ounce of self control to go into a down when I tell him to and to stay there until released while watching the birds hopping around in front of him. Some workers at the cafe on our right were so happy to see him succeed that they started cheering. You can't see them but you will probably hear them. We are on the waterfront near the Torpedo Factory in Old Town Alexandria.
