AKC: Giant Schnauzer breed overview

Working group · Germany

Giant Schnauzer

Also called Riesenschnauzer, Munich Schnauzer

A powerful, clever working dog that thrives on structure and a job, and makes up its own without them.

The Giant Schnauzer was developed in Bavaria to drive cattle and guard farms, butchers and breweries, and later became a police and military dog. It is intelligent, energetic and protective, with a real need for daily training and exercise. With experienced handling it is a devoted family companion; without it, it can be a lot of dog.

Life with a Giant Schnauzer

In the 19th century, farmers and cattle dealers in southern Bavaria wanted a larger version of the Standard Schnauzer to drive livestock to market. Crosses with local herding dogs, and probably Great Danes, produced a big, wire-coated dog that went on to guard butcher shops, breweries and stockyards in and around Munich.

When droving declined, the breed found new work. German police began using Giant Schnauzers early in the 20th century, and they have since served in police, military and search roles. That background shaped a dog that is alert, bold and quick to learn, with a strong urge to protect its family and territory.

At home, a well-raised Giant is loyal and affectionate with its people, often playful well into adulthood and calm once its needs are met. It is not a dog for a passive owner. Without training and a routine, its intelligence and confidence can turn into pushiness, guarding or destruction, and its size makes every mistake harder to manage.

What stands out

Training

Training is the heart of owning a Giant Schnauzer. These dogs learn quickly, remember everything and need a clear framework. They respond best to consistent, reward-based methods with firm boundaries, and they notice inconsistency immediately.

Care guides for the Giant Schnauzer

Feeding5 cups, split into two meals. Females and quieter dogs need less; dogs in serious sport or working training may need more.Read more Puppy growthGiant Schnauzers grow rapidly in the first 6 months, then more slowly until they reach adult height at around 12 to 18 months, and they keep filling out until 2 or even 3 years. A 12-week-old puppy commonly weighs 12 to 15 kg (26 to 33 lb).Read more ExerciseExpect to provide 90 minutes or more of activity a day, including both physical and mental work. Giants thrive in obedience, tracking, protection sports, agility (once mature), canicross and nosework.Read more GroomingThe wiry coat sheds very little, but it still needs regular care. Brush and comb once or twice a week, paying special attention to the beard, eyebrows and leg furnishings, which tangle easily.Read more HealthHip and elbow dysplasia, hypothyroidism, bloat, inherited cobalamin malabsorption and some eye conditions are all recorded in Giant Schnauzers. Black Giant Schnauzers show a higher rate of squamous cell carcinoma of the toe, a tumor of the nail bed.Read more

Giant Schnauzer questions

Is a Giant Schnauzer a good family dog?

For an active, experienced family, yes. Giants are loyal and playful with their own people and can be gentle with children they grow up with. Their size and exuberance can overwhelm toddlers, and their protective streak needs managing when children bring friends home. They do best when one adult leads the training and everyone follows the same rules.

Do Giant Schnauzers shed?

Very little compared with double-coated breeds. Dead hair stays in the wiry coat until it is brushed, stripped or clipped out, which makes them popular with people who dislike hair on furniture. The trade-off is that regular grooming is essential, or the coat mats. Some allergy sufferers tolerate them better than other breeds, but reactions vary from person to person.

What is the difference between clipping and hand-stripping?

Clipping cuts the hair with electric clippers, which is quick and affordable but softens the coat and can fade the color over time. Hand-stripping pulls dead hair out by hand or with a stripping knife, which keeps the harsh texture and deep color. It takes hours and real skill, so most pet owners choose clipping while show exhibitors strip.

Are Giant Schnauzers aggressive?

They are protective rather than aggressive by nature. A well-bred, well-socialized Giant is confident and discerning: friendly with invited guests, alert to anything unusual. Problems usually come from missed socialization, inconsistent training or boredom. Some can be domineering with other dogs, especially of the same sex, so manage introductions carefully.

Can Giant Schnauzers live in apartments?

It is far from ideal. They need a lot of exercise and mental work, and their size and territorial barking can cause friction in shared buildings. An experienced owner who commits to two or more hours of activity a day can make it work, but a house with a secure garden is much easier for both dog and owner.
