Final answer:
A typical dog has approximately 1,000 times more olfactory receptors than a typical human.
Step-by-step explanation:
A typical dog has approximately 1,000 times more olfactory receptors than a typical human.
According to studies, humans have about 400 olfactory receptor genes, while dogs have between 800 and 1,200 functional genes for olfactory receptors.
This significant difference in the number of olfactory receptors allows dogs to have a highly developed sense of smell compared to humans.
