Which dog has a better sense of smell beagle or German shepherd?

The beagle has a better sense of smell than the German shepherd. Beagles are scent hounds, which means that they have been specifically bred for their ability to track scents. They have a large number of olfactory receptors in their noses, and their brains are wired to process scents quickly and efficiently. German shepherds are also intelligent dogs with a good sense of smell, but they are not as specialized in tracking as beagles.
