Comfort Dogs Help Students at Parkland School Heal as Students Return

The father of Florida victim Jaime Guttenberg was waiting to greet students as they returned to Marjory Stoneman Douglas High School for the first time since the shooting. Snapchat video recorded by one student inside a class shows comfort dogs helping them get through the day. David Hogg, a student leader who has become a national figure in the wake of the massacre, says he's focused on one goal, making it through the day.
