Alert Large Dog Breeds
1. Giant Schnauzer
With its commanding presence and sharp intelligence, the Giant Schnauzer stands out as a formidable yet affectionate companion, as per PetMD. Bred in Bavaria to drive cattle and guard property, this breed blends strength with a working spirit that remains evident today.
Giant Schnauzers are intensely loyal and naturally alert, making them excellent watchdogs.

While they can be loving with their families, they do best with experienced owners who understand firm, reward-based training.

Grooming is another essential part of Giant Schnauzer care. Their wiry coats need brushing several times a week and regular clipping or hand-stripping to maintain their rugged, iconic look.
These dogs flourish when given a job, whether it’s obedience, tracking, or dog sports. For the right owner, they’re both a devoted guardian and an enthusiastic working partner.
