Mastador Origin

The Mastador is a crossbreed between the English Mastiff and the Labrador Retriever. This hybrid breed combines the best traits of both parent breeds to create a family-friendly, loyal, and loving dog.

The English Mastiff, from which the Mastador inherits its size, has a rich history that dates back thousands of years to ancient civilizations, such as Egypt and Rome. Known for their size and guarding abilities, Mastiffs were used to protect property, livestock, and people. Over the centuries, their gentle temperament and loyalty made them popular as family pets.

The Labrador Retriever, the other parent breed, originates from Newfoundland, Canada, and was initially bred to assist fishermen in retrieving fish. Later, Labradors were brought to England in the 1800s where they were refined into the loving, intelligent, and skilled working dogs we know today. The breed gained popularity in the USA in the second half of the 20th century and remains the most popular dog breed, according to the American Kennel Club.

The Mastador breed emerged in the USA as dog lovers started crossing purebred Labradors with purebred English Mastiffs. The goal was to create a dog that combined the affectionate and trainable nature of the Labrador Retriever with the protective instincts of the English Mastiff. This breed is designed to be versatile, serving as a companion, guard dog, and family member.

Because the Mastador is a hybrid breed, it is not recognized by the American Kennel Club or other major dog breed registries. However, despite not being a purebred dog, the Mastador has gained a following among dog owners who value its unique qualities and friendly nature.


Size and Weight

The Mastador is a large and solidly built dog, with a muscular body inherited from both of its parent breeds, the Mastiff and the Labrador Retriever. This crossbreed typically stands between 28-36 inches tall. Its weight can range from approximately 100 to 200 pounds, depending on factors such as gender, diet, and exercise.

Colors and Coat

Mastadors come in a variety of colors, including black, yellow, chocolate, silver, fawn, and brindle. Some may even have a distinct mask on their face. The coat of a Mastador is usually short in length and characterized by a shiny double coat. This makes the coat not only attractive but also relatively low-maintenance compared to longer-haired breeds.



Mastadors are known for their gentle, loyal, and affectionate personalities. They are often friendly with children and other pets, making them excellent family companions. Their courageous nature also makes them good guard dogs, while their active and outgoing temperament ensures they thrive in a lively household.


The Mastador is an intelligent breed, inheriting this trait from its Labrador Retriever and Mastiff parents. Their high level of intelligence allows them to learn commands quickly and adapt to their environment, making them an enjoyable and rewarding pet to train.


Mastadors are generally easy to train due to their intelligence, confidence, and eagerness to please their owners. They respond well to positive reinforcement, consistency, and clear communication during their training sessions. It is essential to start training and socialization early to help them develop into well-rounded, caring, and confident adult dogs.

Role in Family and Society

With Children

The Mastador is an excellent family pet, known for its loving and gentle nature. These dogs are large, but they are incredibly gentle and patient with children. They enjoy socializing and playing with kids, providing endless fun and companionship. However, it’s essential to teach children how to interact with such a large dog properly to ensure safety and prevent accidents.

As Guard Dogs

The Mastador is also an effective guard dog, thanks to its natural protective instincts. They are loyal to their family and have a strong desire to protect their loved ones. Despite their friendly demeanor, they can be fierce when they perceive a threat to their family. This makes them both great family pets and reliable guardians.

These dogs display a blend of their Mastiff and Labrador Retriever heritage. They inherit their large size and protectiveness from their Mastiff parent, while their loving and social nature comes from the Labrador Retriever side. This combination makes them versatile pets, fulfilling the roles of both a family companion and a guardian. Proper training and socialization are essential to ensure that these dogs grow up to be well-adjusted members of the family.

Health and Lifespan

Mastadors typically have a lifespan of 10-15 years. As with any breed, maintaining a healthy lifestyle and regular vet checkups are important to ensure a long and happy life.

Common Health Issues

Mastadors, just like any other dogs, can potentially suffer from certain health issues, some of which have genetic components. A few of these health conditions are:

  • Elbow Dysplasia: This joint problem can lead to pain and mobility issues, so it is essential to monitor your Mastador’s physical activities and seek veterinary assistance if you suspect any joint issues.
  • Hip Dysplasia: Similar to elbow dysplasia, this condition affects the hip joint and may cause pain and mobility problems. Regular checkups with a vet can help identify and treat this condition early.
  • Obesity: Mastadors are prone to weight gain, which can lead to obesity and additional health problems. Managing their diet and ensuring they receive regular exercise and maintain an ideal weight is essential in preventing obesity-related issues.

To keep your Mastador healthy, always consult with your vet to receive proper advice and recommendations on diet, exercise, and care. Keep in mind that the experience of your Mastador regarding these health conditions can vary depending on their individual lifestyle and genetic factors.

Exercise and Socialization

Mastador dogs are known for their energetic and active nature, which means they require regular exercise to stay happy and healthy. A daily walk, paired with some play sessions, will help to release excess energy and keep them engaged mentally. It is essential to start establishing an exercise routine with your Mastador as soon as they’re comfortable within their new home.

In addition to physical exercise, Mastadors benefit greatly from early socialization. Introducing your dog to various situations, people, and other animals at a young age will help them develop into a well-rounded and well-socialized adult. This is particularly important for this breed, as they are known for their protectiveness and loyalty, which can be expressed in a positive manner when they’re properly socialized.

One way to ensure proper socialization for your Mastador is by enrolling them in puppy socialization classes, where they can interact with other puppies in a controlled environment. This will help them learn appropriate ways to communicate and become capable of handling social situations successfully. Additionally, exposing your dog to various environments, such as parks, pet stores, and outdoor cafes, will expand their experiences and contribute to shaping their confident and adaptable nature.

It is crucial to keep in mind that Mastador dogs are both physically and mentally energetic. Providing them with a combination of physical exercise, mental stimulation, and social experiences will allow them to develop into well-socialized and well-adjusted dogs, which is essential for the success of a Mastador in a family setting.


Mastadors are a low-maintenance breed when it comes to grooming. However, to keep your Mastador remaining healthy and comfortable, it is crucial to follow proper grooming practices. In this section, we will cover grooming aspects of Bathing and Brushing.


Mastadors don’t require frequent baths, as excessive bathing may strip their coat of natural oils, resulting in dry skin. Generally, it’s good to give them a bath once every 6-8 weeks or as needed. When bathing your Mastador, use a gentle, hypoallergenic dog shampoo specially formulated for sensitive skin. Make sure to thoroughly rinse out the shampoo and always avoid getting water in their ears to prevent infection. After the bath, towel dry your Mastador and allow their coat to air dry completely.


Brushing your Mastador is an essential part of their grooming routine. It helps remove loose hair, distribute the natural oils across their coat, and keeps their skin healthy. Mastadors have a medium-length double coat, which generally does not require extensive combing. However, during shedding seasons (typically in the spring and fall), they will benefit from more frequent brushing to manage the shedding and prevent matting.

To brush your Mastador, use a slicker brush or a de-shedding tool for the best results. Aim to brush your Mastador once or twice a week in normal circumstances, and increase it to daily brushing during shedding seasons. Remember to be gentle and thorough while brushing, reaching down to the skin to remove any loose, dead hair effectively.

Following these simple grooming practices will help your Mastador maintain a healthy coat and keep their skin in good condition.
