However, training a new dog is not easy and can take some time. According to Serena Donnini, a dog trainer for ENCI and the coordinator of the Xylella Detection Dogs experimental programme, there are some dog breeds, such as the springer spaniel, German shepherd, cocker spaniel, and Labrador, that, thanks to their larger nose and chest space, are more likely to become good super smellers and work longer shifts in a self-directed way, often pursuing a scent for hours. But that"s not enough, Donnini says, because a dog"s personality is important too: to pass all the exams to become a detection dogs, the animals must love to play and eat.
