Giant Schnauzer Overview

Giant Schnauzers are only America's 52nd most popular dog breed according to the AKC’s list of popularity from 2025, so you don’t see this breed waltzing the streets as often as other dog breeds.¹ Known as the “wolf in sheep's clothing,” you can’t help but stare at the scruffy titan. Male Giant Schnauzers stand 27.5 inches high and can weigh up to 95 pounds.

Regardless of their size, they live longer than most larger dogs—about 10 to 13 years.

Bred to Defend

The Giant Schnauzer originated in Germany, with development beginning in the 19th century. Breeders used the Standard Schnauzer, and possibly other large working breeds, to develop the Giant Schnauzer.

The Giant Schnauzer excelled as steadfast protectors for all kinds of jobs. But the one job they outshone other dogs in was steering cattle in cattle drives. Before trains, men had to steer cattle for hundreds of miles to supply beef to markets. Giant Schnauzers proved to be excellent guard dogs and companions during long trips.

Sooner or later, cattle drives became a thing of the past, but this didn’t stop the Giant Schnauzer. Because of their natural guarding tendencies, they became helpful as police and military dogs. Giant Schnauzers eventually came to the US and have slowly climbed the popularity ladder.

Giant Schnauzer Care

Exercise

Giant Schnauzers are hard-working dogs that need a job. They should receive at least one hour of vigorous exercise daily. Otherwise, they may become destructive or bored. Long walks and extended ball-throwing sessions are great ideas. Giant Schnauzers will even accompany their owners on long runs, hiking, biking, and other cardio-intensive activities.

Training

A reason Giant Schnauzers are favored is their highly trainable behavior. These dogs are intelligent and territorial, wanting desperately to please and protect their owners. Dog sports can help by giving your Giant Schnauzer mental stimulation, exercise, and boosting their confidence.

You want to start training with dogs as early as possible, especially with Giant Schnauzers. These dogs have a strong working drive and may treat play and training very seriously, so it’s crucial to expose your Giant Schnauzer to various animals and people so they can make this distinction.

Grooming

Giant Schnauzers have dense, wiry coats that require brushing several times per week and frequent clips to maintain skin and coat health. Their infamous beards can become tangled and dirty, so you will also need to wash their face from time to time. With Giant Schnauzers, you will have to visit a groomer occasionally.

The ears should be checked for any sign of infection, and the teeth should be brushed often. Toenails can be clipped when needed.

Do Giant Schnauzers Make Good Family Dogs?

Giant Schnauzers can make great family dogs, but may have some considerations to be aware of. They’re not the happy-go-lucky dogs people often look for in a family dog. A Giant Schnauzer often has strong protective instincts toward its family. This breed has no “clock in, clock out” mindset.

That doesn’t mean Giant Schnauzers are party poopers. They love to have fun as much as the next dog, especially if it means spending quality time with their owners. Giant Schnauzers can be strong, intense, or overly protective around small children if not properly socialized. They can still be around children, but supervision is important.

Overall, these dogs can be territorial, but proper exercise, training, and mental stimulation can help reduce unwanted behaviors. They have a strong work drive, so Giant Schnauzers aren’t for relaxed owners.

Suitable for:

Giant Schnauzers are great family dogs, often protective of their people. These dogs are ideal for homes where they can roam and guard, like a farm or a large backyard. Giant Schnauzers are usually fine with children when properly socialised and under supervision but some can be territorial and sometimes reactive. Depending on the dog's personality, socialisation and introductions, other pets can be good or bad.

Doberman Pinscher Overview

Doberman Pinschers are muscular, powerful dogs with beautiful glistening coats. These dogs are often seen with upright ears and docked tails in some regions, although they’re born with naturally floppy ears. Ear and tail docking are restricted or banned in some countries due to welfare concerns.

Similar to the Giant Schnauzer, Dobermans are large dogs that stand between 24 and 28 inches high. They can live between 10 and 12 years and were the 15th most popular dog breed in America in 2025.

Despite their size and fierce appearances, these dogs are big softies. Still, they’ve served their purpose in history like most working dogs.

Taxes & War

The Doberman Pinscher was developed in the 1880s by Louis Dobermann, a tax collector who experienced hostility during his tax collecting rounds.

Louis Dobermann was looking for a companion to protect him while he walked around town collecting taxes. After breeding with Black and Tan Terriers, various Pinschers, and possibly Rottweilers, he finally created a less refined version of the modern Doberman Pinscher.

This new “tax collector dog” quickly grew in popularity and proved useful as police, military, therapy, and service dogs. During WWII, they were used by the U.S. military as scouts, messengers, and guard dogs. Many of these military working dogs were Doberman Pinschers.

Some of them unfortunately died in service during combat. A life-size bronze statue of a Doberman Pinscher now stands at the US Naval Base in Guam to serve as a reminder of the dogs’ bravery.

Doberman Care

Exercise

Dobermans are high-energy working dogs that need lots of exercise. Long walks, runs, outdoor play sessions, and doggie puzzles are excellent options to keep your Doberman Pinscher entertained.

Training

Dobermans are eager to please their owners and are highly trainable and quick learners. Their time in the war effort proved these dogs are brilliant and can be trained to love and protect. However, their loyalty can get them in trouble sometimes, so early socialization and training are vital to having a mannerly Doberman.

Dobermans also excel in doggy sports. Joining canine competitions in obedience, tracking, and agility will help your Doberman utilize its instincts while remaining a faithful family dog.

Grooming

One of the best parts about Dobermans is that they don’t require much grooming. They still need to be brushed weekly and require regular nail checks and trims as necessary, alongside daily teeth brushing, while they only need a bath once every 6-8 weeks or less often depending on lifestyle.

Do Doberman Pinschers Make Good Family Dogs?

Doberman Pinschers can be excellent family dogs when properly socialised and cared for. Yes, they’re high energy, but they also know when to be serious. Dobermans can often live harmoniously in the same household with children, depending on personality and socialisation, but still require supervision to be on the safe side. 

Overall, they have big hearts and love everyone, as long as you’re not a stranger trying to break into the house!

Unfortunately, the “aggressive breed” perception is frequent with this breed. Some apartment complexes or rental properties may have restrictions on Doberman Pinschers. Even home ownership can be challenging and you may encounter breed restrictions depending on location and insurance policies.

Because of this bias, several cities have introduced restrictions and regulations on keeping the breed. If you want to adopt a Doberman, know that you’ll face challenges with breed restrictions.

Suitable for:

Dobermans are excellent pets for active families looking for a guard dog, and benefit from early socialization with other pets and different environments. They can do well with children under consistent supervision, if they have proper training and socialisation from a young age.

Because of their military background, military families might find they appreciate and understand Doberman Pinschers better.

Which Breed Is Right for You?

The Giant Schnauzer can be independent and may be aloof with strangers but doesn’t crave constant attention like other breeds. This breed does well on farms or homes with a large amount of property.

On the other hand, Doberman Pinschers are highly energetic and love attention. Dobermans do well in small homes as long as they have an outlet to burn energy.

Both breeds are decent with kids and other pets when properly socialised, trained and supervised. Both breeds require early training and supervision to ensure safe interactions during play with children.

Conclusion

The Giant Schnauzer and Doberman Pinscher are both excellent guard dogs that require a great deal of exercise. So, which one works best for you?
