sniff sniff.
here’s what wikipedia says about a dog’s sense of smell:
While the human brain is dominated by a large visual cortex, the dog brain is largely dominated by an olfactory cortex.[28] The olfactory bulb in dogs is roughly forty times bigger than the olfactory bulb in humans, relative to total brain size, with 125 to 220 million smell-sensitive receptors.[28] The bloodhound exceeds this standard with nearly 300 million receptors.[28] Dogs can discriminate odors at concentrations nearly 100 million times lower than humans can.[36]
