The Giant Schnauzer originated in 1832 on pig and cattle farms in the Bavarian Highlands area of Germany. The breed was originally known as "oberlanders" and a written breed standard wasn't established until 1923.
During this time, breeders used Standard Schnauzers to fix the Schnauzer type and from that came the Giant Schnauzer. When World War I was over, the breed decreased in numbers. A kennel owned and operated by C. Clalaminus helped to increase the numbers of the breed. The kennel used three crosses of dogs from other breeds to give the Giant Schnauzer its black color and its neck and head proportions.
The Giant Schnauzer has a wiry outer coat and a soft undercoat. The color of the coat is either grey or black. It weighs anywhere from 70 pounds to 100 pounds and is 23.5 to 27.5 inches tall.
The Giant Schnauzer has low shedding and is hypoallergenic just like other breeds of Schnauzers. The hair of the dog can grow long, however, and the shedding will increase. This increase in shedding can increase allergens if not properly taken care of.
When it trots fast, a Giant Schnauzer will single track and its back will remain flat, firm, and strong.
The Giant Schnauzer is a playful dog but at the same time very protective. The large size of the dog discourages many offenders. It has a herding instinct at a young age so it is good to teach them, as puppies, to not nip.
Some Giant Schnauzers can be very aggressive, which is a common trait for Schnauzers. It is a working dog and so requires plenty of exercise. Any unwanted behaviors are usually caused by not giving the dog enough exercise.
If it doesn't exercise and feels bored the dog will begin to act overly aggressive and so taking it for a jog or letting it play with other dogs will keep the dog calm.
Giant Schnauzers are a water breed meaning that proper training will be needed because anytime they are near water, they will love to jump in.
If you let it off its leash it won't immediately take off. Some Giant Schnauzers will even turn around in mid-stride to make sure the owner is close by. It is a very alert dog and loves to get and give affection from its owners.
The Giant Schnauzer is a very powerful dog that needs a gentle and steady hand along with great leadership. It is a great companion to hang around in your house and is also an excellent jogging partner. The dog is very loyal and not overbearing when it comes to protecting. At times, it can be a little too excitable for small children.
