Jobs Dogs Do, From Guide Dogs to Truffle Hunters

A guide dog stopping at a kerb, a beagle sitting beside a suitcase at the airport, a muzzled dog locating kiwi in the bush: dogs hold a surprising range of real jobs. This list walks through the distinct roles working dogs fill today, from assistance and rescue to detection, farming and the truffle trade. Each entry explains what the job actually involves, how long training usually takes, which breeds tend to do it and where the limits lie, because a dog's nose is remarkable but not infallible. It covers roles, not famous individual dogs.
