Dogs can usually smell smells within a range of 500 meters, but the olfactory sensitivity of different breeds is also different. The noses of some hounds can smell within a range of more than one kilometer. The specific olfactory sensitivity will vary depending on the individual. It's different, but their sense of smell is much stronger than humans.

Tip:

Dogs’ socialization is mainly based on their sense of smell, so we should protect their sense of smell when raising dogs.
