What are the history and origins of the Rottweiler Great Dane Mix?

In order to truly understand the qualities and character of a classic or hybrid breed it is essential to have an idea of their original purpose and development.

So here follows an account of the fascinating history surrounding both the Rottweiler and the Great Dane.

The Rottweiler – Origins and History

The strength and size of the Rottweiler is linked to early interbreeding with Mastiff-like dogs (known historically as Molossus dogs, huge hounds used as both guard dogs and war dogs in Ancient Greece and then Rome). 

It is thought that the Romans interbred these early Mastiffs with versatile and intelligent herding dogs from Northern Europe. It is actually accurate to consider the Rottweiler as a smaller Mastiff with the intelligence and versatility of a herding dog.

The Rottweiler is also believed to have swept around 14th century Germany with the order of Swabian Knights.  Their primary purpose here was the dangerous occupation of ‘catcher-dogs’ tasked with slowing and gripping huge prey, such as the boar, to allow the hunters the opportunity to arrive.

In more modern times the Rottweiler fully proved its worth during WW1.  It was a reliable messenger and deliverer of medical supplies.  This breed  also proved adept at using their tracking skills to locate missing and wounded men.

To this day Rottweilers have proven themselves excellent trackers in keeping with its heritage as a capable hunting dog of yesteryear.

Later in the 20th century this attractive breed became established and popular.   The American Kennel Club first recognized it as a breed in 1931.  The UK Kennel Club followed suit in 1965. The Rottweiler is ranked as the 8th most popular breed in the USA, according to AKC 2020 registration data [1].

 The Great Dane – Origins and History

The Great Dane is often referred to as ‘The Apollo of Dogs’ and is a truly breath-taking breed which combines the strength of the Mastiff with the lean muscularity and height of the Irish Wolfhound.

Originally the companion of nobles and kings even to this day this impressive hound retains a sense of being an aristocrat amongst canines popular not only for its formidable strength and speed but also for its regal appearance.

From the 13th and 14th centuries there are clearer pictorial and written records of the forebears of this giant breed. In Germany they were known as ‘The English Dogge’ owing to it being founded largely on the English Mastiff, which is in itself descended from the large and ferocious ‘Molussus’ dog.

It is thought that extra size and speed of these dogs was contributed to by interbreeding with the Irish Wolfhound, and possibly other Sight-Hounds such as the Greyhound. This added more of a lean, athletic frame while retaining strength and power ].

Although the role of these huge hounds was not to ‘sight’ the prey, but rather they were ‘catcher-dogs’ which ran alongside the horses. Once the prey had been discovered these dogs were sent in to bring down large powerful prey such as boars, deer and even bears.

In 1876 Germany declared the Great Dane as its national dog and pronounced that it should henceforward be known as the ‘German dogg’, but in Holland they continued to call this breed ‘The Dutch Dog’. Finally due to some anathema towards Germany most English-speaking nations settled on Great Dane.

The Great Dane is currently ranked as the 15th most popular breed according to the AKC 2020 registration data [2].

What’s the difference between a Great Dane and a Rottweiler?

In fact the purebred Great Dane might well be described as the biggest lapdog on the planet and have been known to follow their humans absolutely everywhere. Great Danes are one of the clearest examples of a velcro dog who will not want to let their human owners out of their sight.

The Rottweiler is a fiercely loyal dog, but probably as part of its inheritance from the original role of cattle-driving, it is at the same time a little more independent. Rottweilers are more resilient, for example, when left alone in the house for short periods of time.

Expect a Weiler Dane to be a very tactile dog who will be affectionate to its nearest and dearest humans, but also with a streak of independence and slightly less clingy than a pure bred Great Dane.

What is an interesting fact about the Rottweiler Great Dane Mix?

The ancient and powerful Molossus dog, used for both war and hunting, is part of the lineage of not only the Rottweiler but also the Great Dane. This huge hound also gained much of its bulk and strength from interbreeding with these early forebears of the Mastiff.

Dog breeds gain their physical form because of the function they perform. Both tbe Rottweiler and Great Dane were used as ‘catcher-dogs’ gripping large and dangerous prey like boars during the hunt.

So the Great Dane and Rottweiler Mix offers one of those fascinating occasions when lines of origin separate, but then come back together in one very powerful and impressive package.

What is the temperament and personality of the Rottweiler Great Dane Mix (Weiler Dane)?

Although there are some differences in the founding breeds, there is also both common heritage and characteristics. The following offers a general guide to the temperament of the Weiler Dane but with the caveat that a specific dog could favor either of the founding breeds more strongly temperament and behavior. It is therefore also advisable to refer to a breed guide to research both of these founding breeds to get a full overview.

Although the Great Dane is generally more excitable than the Rottweiler, both the founding breeds have generally mellow and well-balanced temperaments. A well-socialized Weiler Dane, therefore, is very likely to possess an even and patient temperament housed within a very formidable and muscular physique.

Although lacking the exuberant playfulness of the Great Dane, the Rottweiler is also gregarious with other dogs and are always happy to play. This means that the Weiler Dane will generally be a friendly play mate although socialization will be important to ensure that play is not too rough with smaller dogs.

The Great Dane has a strong tendency to be unhesitatingly friendly to unfamiliar people, while the Rottweiler is naturally more guarded towards strangers.

This can often lead a more balanced temperament in the Weiler Dane. The Great Dane Rottweiler Mix is less likely to be aloof to strangers than a Rottweiler but will still be very alert to any unwelcome visitors and highly responsive to commands.

Both the Rottweiler and the Great Dane, due to their sheer size, are better suited to a more experienced dog owner, particularly one who has previously had a large breed. This is certainly also the case for the very powerful and large Rottweiler Great Dane Mix.

It is of paramount importance therefore that a Weiler Dane is offered early and consistent socialization to ensure their natural gentleness translates into their play with other dogs and children to avoid any accidental harm being caused by the bulk and strength of these huge hounds.

The Great Dane not only casts a large shadow, but literally becomes a a large shadow as it follows its owners around. The Rottweiler is not quite as ‘clingy’ but is still unswervingly loyal and very keen to please its owners.

The Weiler Dane can therefore be guaranteed to be both protective of the family and a dog who responds to training really well. The Great Dane is biddable, but the Rottweiler influence is likely to enhance this as it is an hyper-trainable breed with high intelligence [2].

What exercise is required for the Rottweiler Great Dane Mix (Weiler Dane)?

Both of the founding breeds are dogs that require and enjoy lengthy exercise of at least a couple of hours a day. This means the Great Dane Rottweiler Mix will be an athletic and outgoing companion happy to accompany their owners on walks, jog and hikes. This intelligent hybrid should also be provided with mental stimulation such as ‘treasure-hunts’, retrieval and chasing games.

This is a dog who will benefit from a good run of the leash each day and can be entrusted to be responsive to recall.

The Weiler Dane is likely to be a very large dog. This means that exercise should initially be compartmentalized into little and often rather than one walk in the very early years. This is because over-exercise can potentially damage bones, ligament and joints in the Great Dane and potentially a large Weiler Dane.

If you are concerned regarding this then it is highly advised that you discuss this with a vet.

Is the Rottweiler Great Dane Mix a good family dog?

The Great Dane Rottweiler Mix is likely to prove larger than life in both senses. This dog will absolutely dote on its human family. With sufficient exercise and stimulation the Weiler Dane will be a largely calm canine companion in the house and a great family dog.

An owner will also need to be fit and strong enough to handle this dog alongside ensuring leash training has been consistently put in place.
