After the attacks of 9/11, nearly 100 trained search dogs and their handlers were deployed by FEMA to help in the rescue efforts at the World Trade Center and the Pentagon.

Composed at close range in natural light, her portraits give an intimate view of the everyday lives of these highly specialised working animals.
