Labradors are an intelligent breed with a good work ethic and generally good temperaments (breed statistics show that 91.5% of Labradors who were tested passed the American Temperament Test.) Common working roles for Labradors include: hunting, tracking and detection (they have a great sense of smell which helps when working in these areas), disabled-assistance, carting, and therapy work. Approximately 60–70% of all guide dogs in Canada are Labradors; other common breeds are Golden Retrievers and German Shepherd Dogs.
The high intelligence, initiative and self-direction of Labradors in working roles is evinced by individuals such as Endal, who during a 2001 emergency placed an unconscious human being in the recovery position, retrieved his mobile phone from beneath the car, fetched a blanket and covered him, barked at nearby dwellings for assistance, and then ran to a nearby hotel to obtain help. A number of labradors have also been taught to assist their owner in removing money and credit cards from ATMs with prior training.
