How is a Fox Terrier’s sense of smell?

Fox Terriers have a very keen sense of smell, plus sharp vision and a lively, alert nature, which is why many hunters like them. They are also loyal to their owners, enjoy playing with children, and are alert enough to serve as good family guard dogs.

However, Fox Terriers have a somewhat eccentric temper and can be unpredictable, seeming calm one moment and suddenly lazy or irritable the next, so they are not well suited to city living.
