ABSTRACT
Dogs have been trained to perform a diverse set of detection tasks. They have been trained to detect estrus in dairy cows, cancer, contamination in aquaculture tank water, compact discs and DVDs, invasive species, accelerants, explosives, narcotics, insect infestations, microbial growth, wood rot, gas leaks, toxins, and scat of a wide range of species. Olfaction in dogs (see Chapter 8 by Goldblatt, Gazit, and Terkel) and other vertebrates involves the action of chemically sensitive sensory cells located in the olfactory epithelium in the nasal cavity.
