When you’re looking for a dog to adopt, it’s possible to become stuck between choosing between two dog breeds you really love. This can happen, for instance, if you want a Golden Retriever or a Bullmastiff! Which of these beautiful dogs should you choose?

Well, what if we told you it was possible to get both dogs in one? Would you believe us? If you’re curious, read on to learn about the Golden Bullmastiff!

We’ve put together information about this dog breed so you can decide if this is the right canine for you and your family. Let’s get started!

What is a Golden Bullmastiff?

The Golden Bullmastiff is a hybrid dog breed that is the result of cross a purebred Golden Retriever with a purebred Bullmastiff! That may seem like an unlikely pairing; however, the result is a very loveable dog! However, there’s not much information about this dog breed because it’s fairly new. But we can learn about these dogs by taking a look at both purebred parents.

Quick Overview of the Golden Retriever

The Golden Retriever originally came from Scotland, where the dogs were bred to retrieve waterfowl and join in the hunt. They also wanted to breed a dog that was a great companion. The result is the Golden Retriever. This dog breed is one of the most popular in the US, andfor a good reasonn. These beautiful dogs have wonderful personalities, are highly intelligent, and are very loyal.

These dogs are very lively and stay this way for most of their lives. Goldens tend to mature slowly, so you could say they’re a bit like Peter Pan in this way. They aren’t considered mature until they’re about three or four years old. Having owned a Golden Mix, however, we have to say that they remain puppy-like until the end of their lives! They’re a joy to have in your life!

Golden Retrievers are active dogs (take our word for it! ) and need plenty of daily exercise. These dogs love to swim, hike, run, and play fetch. They also excel at dog sports. The dogs also need to be with their families most of the time. Otherwise, Goldens can develop separation anxiety. They make amazing family companions, are highly intelligent, and more!

The Bullmastiff

The other purebred parent of the Golden Bullmastiff is the Bullmastiff! These dogs were originally developed in England in the mid-1800s. They were bred by gamekeepers who wanted to develop a dog that was large, fearless, and quiet, with speed needed to catch poachers.

Bullmastiffs are large, powerful dogs that look pretty fierce; however, they also make loving family companions. These dogs must be properly trained and socialized, however. They tend to be confident, loyal, and intelligent dogs.

These are dogs that think independently. If you let them do this all the time, they will soon take over as the dominant member of the family! So, they’re not recommended for inexperienced pet parents.

With parents like these, how could a Golden Bullmastiff go wrong?

The Golden Bullmastiff usually stands between 23 to 27 inches tall and weighs between 85 to 110 lbs. They have a life expectancy of 7 to 10 years.

Golden Bullmastiff Appearance

The Golden Bullmastiff is a hybrid dog, so there’s no standardized appearance. However, it’s safe to say that these dogs can resemble either purebred parent. These are large dogs that have a sturdy, muscular build. If the dog is more like their Bullmastiff parent, he may have a square head with a short, broad muzzle. He would also have a short, dense coat and some skin folds.

If the dog is more like his Golden parent, he will have longer hair with a rounded head and longer muzzle. The dog’s ears may lay down, and their eye color can vary from light to dark brown and their eyes are oval-shaped.

Golden Bullmastiff Temperament

The Golden Bullmastiff is a loving dog that’s very affectionate and loyal to everyone in the family. They are intelligent and somewhat independent. These dogs are sometimes barkers, so, it’s essential to train your fur baby not to bark at an early age.

Are Golden Bullmastiffs Good for Families?

These dogs are great for families that have older kids. The dogs are usually very playful and can be too rambunctious for younger kids.

Does the Golden Bullmastiff Get Along with Other Pets?

The Golden Bullmastiff usually gets along well with other dogs. However, remember these are large dogs! What’s more, they can have a strong prey drive, and they may chase small animals, such as cats, and more.

These dogs are best with a one-dog family with no other pets. Their strong prey drive could make these dogs dangerous for smaller dogs, cats, and other small pets.

Golden Bullmastiff Food Requirements

The Golden Bullmastiff is a large dog that requires about five cups or more of dog food a day, divided into two meals. They require dog food that’s formulated for active giant dog breeds.


Golden Bullmastiffs are very lively, active dogs that require at least 60 minutes of exercise each day. They love walking, hiking, and more! And it’s best to keep them on the leash since these dogs can have a strong prey drive.


These dogs are highly intelligent, yet sensitive fur babies. They learn easily and quickly; however, the pet parent must assert themselves as the leader of the pack, or the Golden Bullmastiff will be happy to fill this role!

The dogs thrive with positive reinforcement training methods, treats, and plenty of praise.

Summing It Up

As you can see, the Golden Bullmastiff is a large, active dog breed that can make a wonderful family companion. These hybrid dogs are the result of crossing a purebred Golden Retriever and a purebred Bullmastiff. The result is an energetic dog that’s friendly, intelligent, and somewhat stubborn.

We’re pretty sure if you adopt a Golden Bullmastiff that you’ll have many adventures and plenty of love in the years to come!
