About the Giant Schnauzer

The Giant Schnauzer is the largest of the three Schnauzer breeds, developed in Germany for herding and guarding livestock and later used as a protection and working dog. It is a powerful, square-built dog with a dense, wiry coat, bushy eyebrows and a beard, normally black or pepper and salt. It combines strength with agility and needs an experienced owner who can provide training and activity.

Temperament

Intelligent, confident and loyal, with strong protective instincts. Can be strong-willed and wary of strangers. Does best with experienced owners who provide firm, fair training and early socialisation.

Exercise

Needs a great deal of daily exercise and mental work, including walks, training and games. Without both it can become destructive.

Grooming

Wiry coat requires brushing a few times weekly and regular professional trimming or hand stripping. Keep the beard clean.

Care & wellbeing

Large, deep-chested dogs need joint care and sensible feeding to reduce bloat risk. Keep lean.

Is a Giant Schnauzer right for you?

  • First-time owners prepared to train consistently

Think twice if

  • You can't give well over an hour of exercise a day, every day
  • You don't have time for frequent brushing or the cost of professional grooming
