40% of the brain goes entirely to their sense of smell. They have a completely different organ that is designed purely to take in the smell, separately from the oxygen they breathe (unlike humans, we process it together).

To put this into perspective, we can taste a teaspoon of sugar in our coffee. They could smell a teaspoon of sugar inside two olympic sized swimming pools.
