What Is A Weimaraner and Mastiff Mix Called?

A Weimaraner Cross Mastiff can also be called a Weimastiff. This is a rare breed, but more information is available regarding each parent breed.

Crossing a Mastiff with a Weimaraner results in a giant-sized dog with a strong and powerful body. The offspring should also be loving, friendly, and gentle in nature.

Although the Mastiffs are generally not very intelligent, this mixed breed should be quite easy to train due to the Weimaraner parent’s inherited traits. But as with other mixed breeds, the personality traits of the Weimaraner Mastiff Mix may vary depending on the parents dominant qualities.

It’s important to learn more about the parent breeds as it helps in predicting this mixed breed’s traits.

With little information available about the Mastiff Weimaraner Mix, let’s find out more about its parent breeds.

The Mastiff

The Mastiff is an ancient breed of dogs. Evidence suggests that this breed’s lineage dates as far back as 2,500 BC in Asia.

The Mastiff breed contributed to the development of several other pure breeds, including the Pug, the Chow Chow, and the Saint Bernard.

Mastiffs are massive dogs that are kept by people from all walks of life. They are adored by celebrities, the police, and ordinary people alike.

There are several Mastiff varieties available around the world and they include English Mastiffs, Neapolitan Mastiffs, Tibetan Mastiffs, and Bullmastiffs, among others.

The most popular of these varieties is the Old English Mastiff (OEM), which is simply referred to as the Mastiff.

The Mastiff has a large body, large head, and broad shoulders. They normally weigh over 100 pounds, but the largest recorded Mastiff weighed 343 pounds.

According to the breed standard, Mastiffs are calm, steady, protective, great with children, and loyal to their families. That’s why crossing Mastiffs with other pure breeds is now a common practice.

The Weimaraner

The Weimaraner was developed by the German nobility to help them hunt big game. The Weim was cherished for his strength, stamina, and sense of smell.

Over time, hunting big game became rare and Weimaraners became useful in hunting small game like birds.

Later, the Weimaraners became cherished family pets, with celebrities and other influential personalities parading their Weims in public.

Weimaraners come in three colors: silver, grey, and blue. That’s why they are often called silver or grey ghosts.

What Does A Weimaraner Mastiff Mix Look Like?

Since all Mastiff varieties have similar characteristics, the appearance of a Mastiff Weimaraner Mix will depend on the parent breed he takes after.

Generally, the Weimaraner Mastiff Mix will have a strong, powerful, and muscular body. They have a large and wide head, a short snout, strong  jaws, and long limbs. If this mix takes after the Weim parent, you can also expect it to be very energetic.

However, the Weimaraner cross Mastiff will also have other unique characteristics that you’ll love. These are floppy ears and blue, amber, brown, or hazelnut eyes.

How Big Will A Weimaraner Mastiff Mix Get?

The Mastiff Weimaraner Mix should be a giant-sized dog, but he can also be somewhere between the Mastiff size and the Weimaraner size.

The Weimaraner reaches around 23 to 27 inches in height, and weighs around 55 to 90 pounds when fully grown.

The Mastiff height falls between 27.5 inches and 30+ inches while their weight averages between 120 and 230 pounds at maturity. As you can see, an adult Mastiff is an enormous dog.

Therefore, the Weimaraner Mastiff Mix size should be the average between the two parent breeds’ sizes. He is likely to be smaller than the Mastiff or bigger than the Weim. It all boils down to the parent breed he takes most after.

Coat and Coat Colors

Just like the parent breeds, this mixed breed has a short coat. Coat colors will vary depending on the dominant features and include silver-gray, brown, tan, and blue.

Weimaraner Mastiff Mixes will also inherit the black nose, muzzle, and ears of the Mastiff parent.

Weimaraner Mastiff Mix Temperament & Personality

Despite being strong and powerful, the Mastiff parent is calm and friendly. The Weimaraner is also known to be loyal, friendly, and affectionate. That means that the Mastiff Weimaraner Mix is a friendly, affectionate, playful, and brave dog that gets along well with other members of the family.

With early training and socialization, he should get along fine with children and other animals. They are also naturally protective and will come to the rescue of their families if they sense any threat. This makes them good watchdogs and family dogs.

Mastiff Weimaraner Mixes are also active and energetic dogs that need daily exercises to be happy and healthy. They can suffer boredom and develop unwanted behaviors if their exercise needs are not met.

Weimaraners are prone to separation anxiety, so the Mastiff Weimaraner can also inherit this trait. For that reason, you should avoid leaving them alone for long hours as they can feel anxious and sad.

Are Weimaraner Mastiff Mixes Protective?

Weimaraner Mastiff Mixes have protective instincts and therefore, make excellent watchdogs. They are always protective of their owner and will not let any intruder pass by unchallenged.

Are Weimaraner Mastiffs Good With Kids?

A Weimaraner Mastiff Mix is great with kids. These dogs display a lot of patience towards children, just like their Weimaraner parents.

However, you should be careful about the size of your Mastiff Weimaraner Mix. They are quite bulky and might accidently hurt smaller kids. Therefore, it’s best to supervise their interactions with toddlers.

Are Weimaraner Mastiff Mixes Good With Other Dogs?

Weimaraner Mastiff Mixes get along amazingly well with other dogs, but they need to be socialized well at an early age. They also require cautious introductions to cats and other pets.

They are large, strong dogs who have a lot of energy and enthusiasm. They may also inherit a high prey drive from the Weimaraner side (because of their hunting history), so they may view smaller pets as their meal.

However, this is not an issue if they are socialized early and raised together with other household pets.

Are Weimaraner Mastiff Mixes Good for First Time Owners?

Weimaraner Mastiff Mixes are not ideal for everyone. First time dog owners should, in particular, consider getting another breed. These pups have a lot of energy and need plenty of physical activities and mental stimulation. Without this, they can become anxious and excitable.

Do Weimaraner Mastiff Mix Dogs Do Well In Apartments?

This mix requires a great deal of daily exercise, so it’s not the best breed for apartment living. These pups can become destructive if not well exercised and mentally stimulated.

So what do these dogs require in terms of exercise? Let’s find out below:

Exercise Needs

Mastiff Weimaraner Mixes are active and energetic dogs who are always up for an adventure. This makes them perfect hiking or running companions.

If your mix inherits his physical traits from the Weimaraner size, they need at least 90 minutes of exercise every day. And if your mix has more physical features inherited form the Mastiff side, it’s advisable to avoid over-exercising them because this breed is prone to bone problems – especially during their puppyhood.

You also want to involve them in off-leash play to help strengthen the bond between you and your dog. This activity can also help stimulate them physically and mentally. Mastiff Weimaraners love humans, and this activity can add to their overall health and happiness.

This mix also needs interactive dog toys to be sufficiently mentally stimulated. Otherwise, they could become a nuisance. So make sure you can provide this before getting a Mastiff Weimaraner Mix.

Do Weimaraner Mastiff Mix Shed a Lot?

The Weimaraner cross Mastiff is a moderate to a heavy shedding hybrid. They generally shed a moderate amount throughout the year, but heavily twice a year.


The Mastiff Weimaraner Mix needs minimal grooming because of their short coat. Generally, brushing their coat once a week should suffice.

Bathing shouldn’t be a frequent activity for these canines. Bathe them just once a month or when it’s necessary to prevent skin issues. The best option is wiping them regularly with deodorizing wipes for dogs if they are not too dirty.

Another area that needs special attention is their ears. With their floppy ears, Mastiff Weimaraners are prone to ear infections, so proper hygiene is essential.

Also, Their nails need to be trimmed at least once a month to avoid splitting or cracking.

Lastly, take care of their muzzle and teeth. Skin folds around the muzzle can cause excess moisture to build up, which can cause infections. On the other hand, plague buildup can cause tooth decay and tooth loss.

Overall, Mastiff Weimaraner Mixes have minimal grooming needs.
