When you think of a service dog, chances are, you think of a German Shepherd on K-9 patrol, a St. Bernard on an Alpine rescue mission, or a seeing-eye dog helping your neighbor walk to the store. Service dogs do so much more for many people in the special needs community. Tune in to PBS tonight for Through the Eyes of a Dog, which features service dogs in some roles that you may not have imagined. Also see http://www.usatoday.com/life/lifestyle/pets/2010-04-20-dogeyes20_ST_N.htm for a USAToday story about the documentary.
