It is hypothesized that this is due to the evolutionary history of male dogs. Male olfactory ability of canines is superior to that of females because historically it was their duty to find mates and mark territory. [1] Canine olfactory sensitivity is also found to diminish, therefore younger dogs tend to have superior tracking than older dogs. [1]
Olfactory enrichment can stimulate naturalistic behavior, enhance exploration, and reduce inactive behaviors. [23] Olfactory enrichment can be utilized by itself, paired with novel toys, or paired with food-based enrichment. This type of enrichment is most commonly used with species that commonly utilize their olfactory senses in the wild.
The dog sense of smell is the most powerful sense of this species, the olfactory system of canines being much more complex and developed than that of humans. [1] It is believed to be up to 10 million times as sensitive as a human's in specialized breeds.
Humans have about 10 cm 2 (1.6 sq in) of olfactory epithelium, whereas some dogs have 170 cm 2 (26 sq in). A dog's olfactory epithelium is also considerably more densely innervated, with a hundred times more receptors per square centimeter. [48] The sensory olfactory system integrates with other senses to form the perception of flavor. [18]
Canine cancer detection is an approach to cancer screening that relies upon the claimed olfactory ability of dogs to detect, in urine or in breath, very low concentrations of the alkanes and aromatic compounds generated by malignant tumors. While some research has been promising, no verified studies by secondary research groups have ...
