Giant Schnauzer History

The Giant Schnauzer originated during the mid-1800s in Germany and the Bavarian Alps (including Bavaria and Wurtemberg). Cattle ranchers needed a bigger, more powerful breed that could effectively herd their cattle.

So breeders developed the Giant Schnauzer by crossing the smaller Standard Schnauzer with other breeds—including the Great Dane. The resulting breed excelled as a guard dog and cattle herder. And its tough coat protected it from the elements.

The breed came to the United States during the early 20th century and was used extensively in police and military work. The American Kennel Club has only recognized Giant Schnauzers for about 50 years—partly because the breed was rare and relatively unknown until the 1960s.

Giant Schnauzer Care


Giant Schnauzers need a high-quality diet that is age-appropriate—whether it's commercially manufactured or homemade (with a veterinarian's supervision and approval).

It's important to keep an eye on the amount of food you give your Giant Schnauzer and reduce the portions if your pup gains weight. Also, remember that giving too many treats in addition to regular meals can contribute to obesity.


The Giant Schnauzer's thick and wiry double coat consists of a soft undercoat and rough outer coat. Weekly brushing and regular clipping/stripping are a must for this breed. Keeping their coats in tip-top shape takes a fair amount of time. And periodic trips to the groomer will help keep the breed looking its best.

Round out your grooming routine by checking your Giant Schnauzer's ears frequently for signs of infection. Brushing their teeth regularly with a dog-formulated toothpaste is also integral to their overall health.


Giant Schnauzers have more energy than most big breeds and require a tremendous amount of exercise. They enjoy dog sports such as agility, tracking, herding, carting, rally, and competitive obedience. A long daily stroll, playdate with other dogs, and games in a fenced yard are also sufficient ways to satisfy your pup's mind and body.


Giant Schnauzers are intelligent dogs. But they can be hard-headed. Lessen these stubborn tendencies by using reward-based training methods involving small treats and favorite toys. Training should be firm, consistent, and gentle—and start at an early age.

The Giant Schnauzer learns quickly and needs to have a job, even if it's as simple as chasing a ball. This breed is often reserved around strangers. But Early socialization can help prevent this behavior and reduce any defensive, aggressive tendencies.
