Dogs' smell ability is about 10000-100000 more developed than humans' one. Dogs smell is usually exploited in forensic medicine, to find missing people and specific substances showing peculiar sensorial features. In clinic, there is the possibility to take advantage of dogs smell, which are conveniently trained, for the screening of cancers and other diseases. The common feature is the presence of molecules in organic samples that may be considered as biomarkers of a specific pathology. In cancer, scientific evidences exist about screening of melanoma, lung, breast, rectum, ovarian, prostate and bladder cancer. Instead, other pathologies manifest the presence of organic volatile compounds in biologic materials, such as spit, faeces and urine that may be studied by dogs smell in order to identify the presence of a specific disease. This review shows the state of the art of actual dogs' olfactory ability based on scientific principles and the advantages and the disadvantages of this method. The authors also reveal some potential pathologies joined by the presence of organic volatile compounds, which may be investigated by dogs smell.

Abstract
Dogs' smell ability is about 10000-100000 more developed than humans' one. Dogs smell is usually exploited in forensic medicine, to find missing people and specific substances showing peculiar sensorial features. In clinic, there is the possibility to take advantage of dogs smell, which are conveniently trained, for the screening of cancers and other diseases. The common feature is the presence of molecules in organic samples that may be considered as biomarkers of a specific pathology. In cancer, scientific evidences exist about screening of melanoma, lung, breast, rectum, ovarian, prostate and bladder cancer. Instead, other pathologies manifest the presence of organic volatile compounds in biologic materials, such as spit, faeces and urine that may be studied by dogs smell in order to identify the presence of a specific disease. This review shows the state of the art of actual dogs' olfactory ability based on scientific principles and the advantages and the disadvantages of this method. The authors also reveal some potential pathologies joined by the presence of organic volatile compounds, which may be investigated by dogs smell.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
