There are some awesome photos by Bonnie Block. She does dogs photos at the trials as well as calendars, notecards and so forth. I have known Bonnie over nine years and she is one of the kindest people that I know. She helped me pick out a new camera and gave me a lesson.
Here are some photos that Bonnie took of Tess, Faye and Nan. Notice how she captures the expressions of each dog.
Faye (daughter of Nan). Now owned by Tony.
