Nope! Giant Schnauzers are actually working dogs. Their smaller relatives, the Miniature Schnauzers, are classified as terriers, which can sometimes cause a bit of confusion. Miniature Schnauzers were specifically bred to hunt vermin, a typical terrier trait, whereas Giant Schnauzers were bred for herding and guarding. People looking for a large hypoallergenic dog often find themselves deciding between Giant Schnauzers and Airedale Terriers, as both share a similar square body shape and rectangular head.
