Will a Great Dane Attack an Intruder? An In-Depth Look at the Gentle Giant of Guard Dogs

As a lifelong dog lover and veterinarian, I‘m constantly fascinated by the many roles that our canine companions play in our lives. From loyal pets to dedicated working dogs, there‘s no limit to the ways that dogs can enrich and protect us. One breed that has captured my heart over the years is the Great Dane – a majestic, towering breed known for its gentle spirit and fierce loyalty.

But as much as I adore the sweet nature of Danes, I also know that these dogs have a long and proud history as guardians and protectors. Time and again, I‘ve seen evidence of the breed‘s powerful defensive instincts and unwavering courage in the face of danger. So that raises the question – will a Great Dane actually attack an intruder to defend its home and family? Let‘s take a closer look at the guard dog potential of these gentle giants.

A Noble History of Protection

The Great Dane may be a gentle soul, but this breed was originally developed for a much more fierce purpose. In the grand estates and castles of 16th century Germany, the Dane‘s ancestors were used by nobility as ferocious boar hounds and estate guardians. These early Danes were crossbred with Irish Wolfhounds and English Mastiffs to create a larger, more imposing dog to accompany noblemen on hunts and guard their property.

One famous example was Bismarck, the treasured Great Dane of German Chancellor Otto von Bismarck in the 1800s. Bismarck the Dane was known to accompany the Chancellor everywhere and fiercely defend him against any perceived threats. Another notable Dane guardian was Jua, who guarded the Lusaka Museum in Zambia for many years and was known for physically tackling intruders who dared to enter after hours.

So while the modern Great Dane may be a more mellow creature, those guardian instincts still run deep in the breed‘s blood. A well-bred Dane innately knows that it is their solemn duty to serve as a watchful protector for their pack and territory. And they have both the courage and capability to do it.

The Imposing Power of Presence

The first and most potent weapon in a Great Dane‘s arsenal is the sheer awe factor of their size. An adult male Dane in peak condition can stand up to 32 inches at the shoulder and weigh anywhere from 140-175 pounds of pure muscle. That‘s a whole lot of dog staring down at you with a suspicious glare.

Research has shown that the vast majority of intruders will simply flee immediately upon spotting a dog of the Dane‘s stature. In a study of convicted burglars, over 95% said that a large, visible dog was the biggest single deterrent when choosing a target. One burglar was quoted as saying "I‘m not afraid of dogs, but big ones make me think twice."

Speaking of making intruders think twice, we can‘t forget the deep, booming bark of a Great Dane on full alert. That window-rattling "boof" is both startling and sonorous, sounding like it should belong to a creature twice a Dane‘s size. The acoustic power of a Dane‘s warning bark comes from its deep chest cavity and the dense musculature supporting its lungs. When those mighty jaws open up, you feel the bark as much as you hear it.

Anecdotally, I‘ve had many Dane owners tell me stories of would-be trespassers taking one look at their fired-up Dane and promptly sprinting in the opposite direction. The sight and sound of an angry Great Dane is more than enough to dissuade all but the most foolhardy of intruders. As one of my Dane-owning clients put it, "Just one ‘woof‘ from Gus is worth ten deadbolts on the front door."

Gentle Until Provoked

But of course, the Great Dane‘s guard dog prowess goes beyond just looking and sounding scary. These dogs are absolutely willing and able to back up their bark with a bite if they feel it‘s warranted. With a bite force of over 500 psi, a Dane‘s jaws are incredibly strong – just a little less than a Rottweiler‘s.

However, the key difference with Danes is that they tend to be far less indiscriminate with their aggression compared to many other guardian breeds. Danes are famous for their sweet, tolerant nature, especially with children. They are not a highly suspicious or reactive breed by nature, preferring to meet the world with a calm, friendly confidence.

In my years of working with the breed, I‘ve found that most well-socialized Danes will only resort to attacking as an absolute last resort, when all other deterrent options have been exhausted. These are not dogs who lash out at every unfamiliar person or go looking for a fight. A Dane‘s first instinct is always to neutralize a threat through intimidation, either by pinning an intruder or holding them at bay until help arrives.

But make no mistake – if a Great Dane feels that its family is in imminent danger, it will tap into that dormant hunting aggression and meet force with force. There are countless documented cases of Danes fighting off armed assailants, chasing down burglars, and even laying down their lives to save their owners from harm.

A famous example was a Harlequin Dane named Charlie, who in 2010 fought off a violent home invader and was stabbed multiple times while defending his owner. Despite his grievous wounds, Charlie managed to hold off the attacker long enough for police to arrive, saving his owner‘s life. He later made a full recovery and was honored with a local hero award.

This is the essence of what makes Danes such exceptional guardian dogs – the perfect combination of even-tempered discernment and unhesitating courage. They are that rare breed of dog that can be both a stalwart protector and a gentle, affectionate family pet, all in one massive package. As one K9 training expert I interviewed put it, "A good Dane has an off-switch. They can go from happily romping with the baby to full-on protection mode in a heartbeat, but it takes a heck of a threat to flip that switch."

Choosing and Training a Guardian Dane

So if you‘re considering a Great Dane as a guard dog for your family, what should you look for? As with any breed, the foundation of a successful guardian dog is proper breeding, socialization and training.

When selecting a Dane puppy as a potential protector, look for a poised, confident pup who readily approaches new people and stimuli. A good guard dog prospect should be curious and alert, but not timid, hyperactive or aggressive. Avoid the extremes of shyness and sharpness, as they can lead to fear-biting and overreactions down the line.

From the moment your Dane pup comes home, socialization is key. Exposure your Dane to a wide variety of people, animals, environments and situations from an early age to help them understand normal vs. not normal. The more stable, real-world experiences a Dane has to draw upon, the better they‘ll be at discriminating between friendly strangers and genuine dangers.

Obedience training is also a must for any Dane, but especially a guardian. Your Dane needs a reliable recall and a solid "leave it" or "stop" command in case they get too riled up and need to disengage. training also deepens the bond and communication between dog and handler, which is crucial for a protection dog.

If you do decide to pursue any kind of formal guard dog or protection training with your Dane, I can‘t stress enough the importance of finding an experienced, positive-methods trainer. Techniques based on force, fear and pain have no place in creating a stable guardian, and can seriously backfire with a sensitive breed like a Dane.

The goal should be to enhance and channel the Dane‘s instinctive guarding nature, not to force them into the role of an attack dog. Even without specialized training, a well-bred and socialized Dane who is devoted to its family will instinctively rise to their defense in a crisis. Trust in your dog‘s natural judgment and commitment to its pack.

The Drawbacks of a Dane Defender

As magnificent as a Great Dane can be in a guard dog role, there are some potential downsides to relying on the breed for protection as opposed to one of the more traditional guardian breeds. It‘s important to understand and weigh these factors before purchasing a Dane for home defense.

First, that gentle Dane nature can sometimes be a little too gentle in a high-pressure situation. Some Danes, especially those at the mellower end of the temperament spectrum, are so friendly and tolerant that it takes a severely provocative threat to switch them into defense mode. These dogs may be more likely to stand their ground and bark to alert you rather than immediately engaging an intruder.

Secondly, even the largest Dane can be more physically fragile than a squatter, more muscular guardian breed like a Rottweiler or Bullmastiff. The Dane‘s extreme size puts a lot of strain on their joints and bones, making them more susceptible to conditions like hip dysplasia and arthritis that could impede their long-term soundness as a protector. There‘s also the unavoidable fact that giant breeds like Danes have significantly shorter lifespans than their medium-sized guardian counterparts.

There are also some practical considerations with owning a dog as large as a Great Dane. Everything from food to medications to containment needs to be supersized (and super expensive). A Dane in full protective mode can easily knock over a small child or elderly family member in the heat of the moment. And you‘ll need a vehicle big enough to transport your defense Dane, especially in an emergency situation.

But for me and many other devoted Dane owners, the breed‘s unparalleled combination of valiant spirit and loving heart more than makes up for these drawbacks. A Dane‘s primary function should always be as a cherished family companion first and foremost, with their protective abilities serving as a priceless bonus. The greatest guardian asset a Dane can offer is the incomparable emotional security and comfort of their stalwart presence in your daily life.

A Gentle Soul, a Mighty Guardian

When all is said and done, the Great Dane is a masterful amalgamation of a gentle companion and a fearless defender. They may not have the sharpest edge or the most ferocious reputation, but underestimate their protective instincts at your own peril. A Dane‘s unwavering loyalty and courage, combined with their highly discerning judgment, allows them to be both a sweet family pet and a formidable deterrent in equal measure.

For most households, a Dane‘s mere presence as a physical and visual deterrent is more than enough to send any sensible intruder packing without the need for actual violence. But should the unthinkable happen, these brave and noble dogs will not hesitate to use every ounce of their strength to defend their pack.

As a veterinarian and an unabashed Great Dane devotee, I have the utmost respect for this breed‘s phenomenal versatility, and I will never cease to be amazed by the depths of their devotion. To watch a Dane seamlessly switch from a patient, gentle playmate to a living, breathing fortress of protection is to witness the true essence of a guardian breed.

So to all of my fellow dog lovers considering a Great Dane – know that you are choosing so much more than just a pet. You are welcoming a majestic, multifaceted creature into your life, one who will love you with every fiber of their being and defend you with every inch of their impressive stature. With a Dane by your side, you can rest easy knowing that you have both a gentle giant and a glorious guardian watching over your castle and your heart.
