History and origin

The FCI standard says the Giant Schnauzer was originally used in southern Germany for driving cattle. Around 1900, breeders saw that it had excellent working qualities and a remarkable character. It has been recorded in a stud book since 1913, and in 1925 it was officially recognised as a working dog.

Wikipedia says that after helping on farms and guarding homesteads, it moved to the city, where it guarded breweries, butchers' shops, stockyards and factories. It was almost unknown outside Bavaria until it became popular as a military dog in the two world wars.

Physical characteristics

The standard describes it as a large, powerful dog, stocky rather than slender, an enlarged and powerful version of the Schnauzer. It is an imperturbable dog, ready to defend, whose appearance commands respect. The body is square.

General appearance

The not-too-soft beard on the muzzle and the bushy eyebrows, which slightly shade the eyes, are typical features. The coat is short on the forehead and ears. The AKC says a well-bred Giant Schnauzer looks like the Standard Schnauzer, only bigger.

Height at the withers 60–70 cm

The FCI standard accepts black and pepper and salt. Wikipedia mentions three varieties: pepper and salt, pure black with a black undercoat, and black and silver.

Training and socialisation

The standard says its good nature, balanced temperament and incorruptible loyalty to its owner are its typical traits. It has highly developed senses, is intelligent, easy to train and strong.

The AKC says it is extremely intelligent and very territorial, loves its owners and feels responsible for protecting them. It learns quickly and can tell friend from foe. It cannot bear to be ignored or left alone in the yard, and it needs a job.

Tips for effective training

  • Give it a job. The AKC says it needs an activity, even a simple one.
  • Do not leave it alone in the yard. It wants to be with its owners.
  • Socialise it thoroughly. It is very territorial.
  • Be consistent. It is clever and tests boundaries.

Activity needs and lifestyle

The AKC says it is more energetic than most large breeds and needs plenty of exercise. It is a great partner for running, cycling, hiking, cross-country skiing, swimming or skijoring.

Activity How often Why it matters
Long walks or running daily Very high energy
Play with another dog several times a week Burns off energy
Training or dog sports several times a week It needs a job

Tips for a balanced life

  • It suits an active, experienced owner.
  • The yard must be well fenced.
  • Be ready to care for its coat.

Care and health

Coat and skin care

The AKC says the wiry double coat should be brushed weekly and clipped or stripped regularly. The owner must make time for it or take the dog to a groomer periodically.

Common health problems

The AKC says the breed is generally healthy, and breeders test for:

Condition Description Common symptoms
Hip dysplasia The hip joint forms incorrectly and, over time, arthritis develops Limping, difficulty getting up or jumping, hip pain
Eye diseases Inherited eye conditions Poor vision, cloudy eyes
Autoimmune thyroiditis The body attacks the thyroid gland Weight gain, tiredness, dull coat
Gastric dilatation-volvulus (bloat) The stomach fills with gas and may twist; this is a veterinary emergency Swollen belly, trying to vomit without success, drooling, restlessness

Other care

  • Clean the beard after meals.
  • Check the ears regularly.
  • Trim the nails when they start to touch the floor.

Diet and nutrition

The AKC recommends good-quality food suited to its age and activity level. Too many treats lead to obesity.

Tips for a healthy diet

The table gives a starting estimate, calculated with the formula from the Merck Veterinary Manual. The first two calorie columns show the calories per day for a healthy adult dog. The last column shows what this means in dry food with 3,500–4,000 kcal per kilogram.

Dog's weight Calories per day (neutered) Calories per day (not neutered) Dry food per day (approximate)
35 kg 1,610 kcal 1,810 kcal 400–520 g
41 kg 1,810 kcal 2,040 kcal 450–580 g
47 kg 2,010 kcal 2,260 kcal 500–650 g
  • Split the food into two meals a day to reduce the risk of bloat.
  • Do not let it run right after a meal.
  • A dog is at the right weight when you can feel its ribs under the coat without pressing hard.

Foods to avoid

Some human foods are dangerous for dogs: chocolate, coffee, grapes and raisins, onions, garlic, xylitol (a sweetener used in chewing gum), macadamia nuts and alcohol.

Reproduction and development

Physical and emotional maturity

In dogs, sexual maturity usually comes between 6 and 12 months, but in large breeds it can be delayed until about two years. The body also reaches its adult form later than in small breeds.

Mating and pregnancy

Pregnancy lasts about 63 days, counted from ovulation. Mating a female on her first heat is not recommended. The FCI standard requires that only healthy dogs of typical breed appearance are used for breeding.

Caring for the puppies

In large breeds, a litter has around 7 puppies on average. Socialisation starts in the first weeks: gentle handling, everyday noises and new people.
