Whether they are providing comfort to victims of trauma, sniffing for bombs and drugs, or assisting with tasks of daily life, service and therapy dogs are at work every day. Mindy Todd talks on The Point about one of the earliest American programs to train service dogs with Susan Wilson, author of “A Man of His Own." This novel centers around a dog volunteered for the World War II Dogs for Defense program. Mindy then sits down with Elaine Lomenzo, a volunteer puppy raiser with Canine Companions, a program providing trained assistance dogs to adults and children with disabilities.
