How good are human noses?
Humans tested as generally more sensitive sniffers than monkeys and rats on a limited range of odors. In fact, humans detected certain scents at lower concentrations than the notoriously top-notch nostrils of mice and pigs. Humans even beat the indomitable dog for at least a handful of scents.
Why do humans smell worse than animals?
Humans turn out to be particularly smelly because odors are released from nearly every part of the body while other species living on us are simultaneously emitting odors too.

Do dogs have better sense of taste than humans?
