Mini Great Danes: Everything You Could Want to Know

The idea of a Mini Great Dane sounds like the perfect compromise. You get the majestic look and gentle temperament of a Great Dane in a smaller, more manageable package. But before you start searching for breeders, there are some important things you need to understand about what a “Mini Great Dane” actually is, how they are bred, and whether they are a good choice for your family.

What Exactly Is a Mini Great Dane?

A Mini Great Dane is not an officially recognized breed. There is no miniature version of the Great Dane that has been selectively bred over generations by reputable breeders. Instead, “Mini Great Danes” are typically created in one of three ways, and each method comes with its own set of concerns.

The first method is breeding runts together. Breeders take the smallest Great Danes from different litters and breed them to produce smaller offspring. While this does reduce size over a few generations, runts are often small because of underlying health problems. Breeding unhealthy dogs together tends to produce even unhealthier puppies.

The second method is crossbreeding a Great Dane with a smaller breed. Common crosses include Great Dane and Labrador Retriever mixes or Great Dane and Boxer mixes. These dogs may look somewhat like smaller Great Danes, but they are mixed breeds with unpredictable traits. You might get a dog that looks like a small Great Dane, or you might get something that looks nothing like one.

The third method involves introducing the dwarfism gene. This produces a dog with a standard sized body but shortened legs. Dogs with dwarfism often suffer from serious spinal and joint problems throughout their lives. This method is considered unethical by most veterinary professionals and breed organizations.

How Big Is a Mini Great Dane?

Since there is no standardized breed, Mini Great Danes vary widely in size. Most fall somewhere between 25 and 30 inches tall and weigh between 50 and 100 pounds. For comparison, a standard Great Dane stands 28 to 32 inches at the shoulder (often taller) and weighs 110 to 175 pounds. So while Mini Great Danes are smaller, they are still medium to large dogs by any standard.

If you are looking for a truly small dog, a Mini Great Dane is not it. Even the smallest ones are bigger than most medium sized breeds. The name “mini” is relative to the massive size of a standard Great Dane, not to dogs in general.

Mini Great Dane Temperament

The Great Dane temperament is one of the breed’s biggest selling points. They are gentle, affectionate, patient, and remarkably good with children for a dog their size. Mini Great Danes bred from purebred Great Dane parents tend to inherit these same personality traits.

However, Mini Great Danes created through crossbreeding will have temperament traits from both parent breeds. A Great Dane mixed with a Labrador might be more energetic and mouthy. A Great Dane mixed with a Boxer might be more stubborn and playful. You cannot guarantee the temperament of a mixed breed the way you can with a well bred purebred.

One thing that holds true regardless of how they were bred is that Mini Great Danes are social dogs that do not do well when left alone for long periods. They bond deeply with their families and can develop separation anxiety if they do not get enough companionship and attention.

Health Concerns with Mini Great Danes

This is where things get serious. Standard Great Danes already have a shorter lifespan than most breeds (7 to 10 years) and are prone to a number of health issues. Mini Great Danes can inherit all of those same problems, plus additional ones related to how they were bred.

Bloat (Gastric Dilatation Volvulus) is the number one killer of Great Danes and their mixes. The stomach fills with gas and can twist on itself, cutting off blood supply. This is a life threatening emergency that requires immediate surgery. Mini Great Danes with deep chests are just as susceptible as their full sized counterparts.

Heart Disease is common in the breed, particularly dilated cardiomyopathy (DCM). This condition causes the heart to enlarge and weaken over time, eventually leading to heart failure. Regular cardiac screenings are important for any Great Dane or Great Dane mix.

Joint and Bone Problems are a major concern, especially in Mini Great Danes bred through the dwarfism gene. Hip dysplasia, elbow dysplasia, and intervertebral disc disease can cause chronic pain and mobility issues. Even without dwarfism, rapid growth in large breed puppies can lead to developmental orthopedic diseases if they are not fed an appropriate large breed puppy food.

Hypothyroidism affects many Great Danes and their mixes, causing weight gain, lethargy, skin problems, and coat changes. It is manageable with daily medication but requires lifelong treatment.

Should You Get a Mini Great Dane?

Before you commit to a Mini Great Dane, consider these honest pros and cons.

On the positive side, you get a dog that likely has the wonderful Great Dane personality in a somewhat more manageable size. They require less food, are easier to transport, and may fit better in smaller homes than a full sized Great Dane. For people who love the breed but cannot physically manage a 150 pound dog, a Mini Great Dane can seem like the perfect solution.

On the other hand, Mini Great Danes come with significant risks. Breeders who specialize in miniaturized versions of breeds often prioritize size over health, which can mean higher vet bills and a shorter lifespan. There is no breed standard to hold breeders accountable, and many “Mini Great Dane” breeders operate outside of any breed club or health testing programs.

If you do decide to get a Mini Great Dane, do extensive research on the breeder. Ask for health test results on both parents, visit the breeding facility in person, and talk to previous buyers about their dogs’ health. Be prepared for the possibility of higher veterinary costs than you might expect for a “smaller” dog.

Better Alternatives to Consider

If you want a dog that looks or acts like a Great Dane but in a smaller package, there are some established breeds worth considering. A standard Great Dane might be a better option than you think. Despite their size, they are surprisingly adaptable to smaller spaces because they are calm and low energy indoors. Many Great Dane owners in apartments say their dogs take up less functional space than a hyperactive medium sized breed.

A Boxer shares many personality traits with Great Danes. They are playful, gentle with children, and affectionate with their families. They stand 21 to 25 inches tall and weigh 50 to 80 pounds, making them a naturally smaller alternative without the health risks of miniaturization.

A Weimaraner is another option for people who love the sleek, athletic look of a Great Dane. They are slightly smaller (23 to 27 inches tall, 55 to 90 pounds), incredibly loyal, and have that same regal appearance. They do require more exercise than a Great Dane, so keep that in mind.

A Greyhound or retired racing Greyhound is perhaps the closest match in terms of body type and temperament. They are tall and lean, gentle, quiet, and surprisingly lazy around the house. Greyhound rescue organizations always have dogs available that are looking for loving homes.
