At a glance
Ratings describe typical dogs of the breed on a 1–5 scale. Individual dogs vary with lines, upbringing and training.
Temperament
Giants are bold, alert and deeply loyal to their families. They are natural guardians, often wary of strangers, and thrive when given a job such as obedience, protection sports or search and rescue.
They need a lot of exercise and mental stimulation. Without it they become bossy, destructive or noisy. Firm, fair and consistent training from puppyhood is essential.
Living with a Giant Schnauzer
Exercise
Needs 90 minutes or more of vigorous daily activity plus training. Ideal for runners, hikers and dog-sport enthusiasts.
Grooming
Brush several times a week and book professional grooming every six to eight weeks. Wash the beard after meals.
Training
Very trainable and eager to work, but strong-willed. Start socialisation and obedience early and keep training varied.
Kids & other pets
Loyal and protective with their own family; boisterous with small children. Can be dominant with other dogs.
Time alone
Giants dislike being left alone for long periods and can become destructive without exercise and company.
Home fit
Best suited to a house with secure outdoor space; apartment living is hard on this breed and its neighbours.

Cost to own
After the first year, expect roughly $1,500–$3,000 a year for food, routine vet care, preventives, insurance and supplies (US estimate).
- Professional grooming every 6–8 weeks adds roughly $500–$900 a year.
- Food, medication and anaesthesia are dosed by weight, so every vet visit costs more for a big dog.
- Pet insurance for a puppy typically runs $30–$60 a month; premiums rise with age and breed risk.
History
Bavarian farmers in the 1800s crossed Standard Schnauzers with larger dogs, likely including Great Danes and Bouvier-type drovers, to create a big dog for driving cattle to market and guarding farms and breweries.
When railways replaced cattle drives, Giants found new work as police and military dogs. The AKC recognised the Giant Schnauzer in 1930.
