Unfortunately, not all scientific articles reported exactly what the dogs were trained to detect cancer. It is interesting, however, that in most cases it was dogs Pets whose owners lived near the hospitals or universities where the study was conducted. Only one study has attracted owners of sport dogs, Champions in obedience.
In the works, where were obtained the highest results, the researchers used Golden retrievers, Labradors, Portuguese water dogs, a Schnauzer and mittelschnauzer. In the works where dogs were not able to “diagnose” that the scientists modestly silent about of the breed of Pets, especially that one works it was a dog that belonged to the trainers. In all cases, scientists used to train dogs “clicker training”.
