The History of the Mastiff Lab Mix

Like many other cross breeds, the history of the Mastador dog is not well defined.

It is also not clear if the two parent dogs were intentionally brought together or if the original Mastador dog was a happy mistake.

It is widely believed that the Mastiff Lab Mix has its roots in the United States.

To know more about what to expect from a Lab and Mastiff Mix, let’s take a closer look at the origins of the parent breeds.

The History of the Bullmastiff

The Bullmastiff was bred in England in the mid 1800s. The breed is a cross between the ancient English Mastiff and the Bulldog. At first, this breed was 40% Bulldog and 60% Mastiff. The aim of this breed was to create a dog with great watchdog capabilities.

The large size and bravery shown by the resulting dog made them ideal for gamekeeping roles.

At first, brindle colored dogs were used as gamekeepers thanks to their capability to camouflage at night.

The Bullmastiff was officially recognized by the AKC in 1934.

The History of the Labrador Retriever

The Labrador Retriever was originally developed in Newfoundland. The breed was preferred by fishermen, as these dogs would help in pulling carts and nets loaded with fish.

The original Labradors were smaller than the present-day labs. It is said that there was a tiny dog in the region called St. John’s dog. These dogs were crossed with giant hunting dogs that moved to the area from England. The new dogs gave birth to the modern Labrador.

The dogs became extremely popular in Europe for their great hunting skills. The Earl of Malmsbury named them ‘Labradors’ and the original Labrador Club was established in England in 1916.

The Labrador was first recognized by the AKC in 1917. Labradors are currently some of the most popular dogs in the United States.

Lab Mastiff Mix Behavior and Temperament

Being a cross breed, the behavior and personality of the Mastador will vary from one dog to another, and even same litter puppies will behave differently.

All debates aside, let’s take a look at what’s generally believed to be the behavior and temperament of the giant Mastador dogs.

Don’t let the large size of this pooch fool you; Mastadors are generally friendly, outgoing, loving, protecting and loyal dogs. They love children, but their big size might not be ideal for young kids. Such big dogs may harm them without intending to.

Mastador dogs are great guards and will protect those close to them and their own territory. These dogs are not very aggressive towards people and other animals and usually get along well with other dogs when properly socialized from a young age.

They love taking part in family activities and should not be left alone for far too long to help prevent boredom and separation anxiety. A bored Mastiff Lab Mix can exhibit destructive behavior.

Moreover, a Mastador has a great sense of smell thanks to his Labrador genes. While these dogs are generally calm, they can become aggressive towards strangers. His deep frightening bark can help scare away potential intruders. That’s why these dogs make great guard and family dogs.

As long as these dogs know their families are safe, they will be calm and relaxed. Your Mastador will happily watch over your small baby as you attend to your daily household chores. He will also be happy to join you on your regular runs or exercises. So if you need a dedicated workout buddy, this is the right dog for you.

Training and playtime will help your Labrador Mastiff puppy to develop into a happy and well behaved dog.

Training and Exercise Needs

How Active Should My Mastiff Lab Mix Be?

These dogs should be exercised regularly to expend their excess energy. Nevertheless, unlike many other dog breeds, lack of daily exercises does not necessarily make them aggressive or restless. Instead, your Mastador will assume his natural docile status, but that is not good for your dog. He requires daily exercises to keep his big and strong body fit and healthy.

Moreover, keep in mind that your Mastiff Lab puppy will be very big and strong once he is fully grown. If you do decide to take your dog out for daily walks, you should be well prepared to keep him on leash. Or else, he will pull you across the road while chasing after a rabbit.

Fortunately, Lab and Mastiff Mix dogs are not demanding as far as finding a good place and time to play goes. Your Mastador will enjoy various activities whether it’s indoors or outdoors. If you don’t want to go out for any reason, your dog will happily play with you within the confines of your home. You’ll learn to appreciate this when the weather is too cold for them.

Mastiff Lab Mix dogs are generally smart and training should be a breeze if you know how to go about it.

As an offspring of a Bullmastiff, your Mastador is intelligent and training should be easy and fun for both of you. Therefore, a Mastador is a great choice for anyone looking to buy or adopt a dog who requires little in terms of socialization and training.

Mastador Grooming Needs

Another advantage of owning a Mastador is that he is a low- maintenance dog when it comes to grooming.

Lab Mastiff Mixes have a natural smooth coat that will require moderate brushing. Nonetheless, he is not hypoallergenic and therefore, vacuuming your seats and carpets is important.

Bathing can also be challenging and time-consuming considering his big size. You can take him out for a swim or consider a fun splash as you clean your car! This is usually enough to keep his coat clean and leave him feeling fresh.

When it comes to hygiene, the only challenge is cleaning his ears. Mastadors have droopy ears, which are vulnerable to wax build-up and certain infections. Therefore, make sure to clean his ears thoroughly and regularly to avoid infections.

Also, remember to brush his teeth at least twice per week for improved oral hygiene.

Bull Mastiff and Labrador Mix: Health Problems

Just like other hybrid dogs, your Mastiff Lab Mix dog may inherit certain health problems from his parents.

Many dog breeders claim that designer dogs, like the Mastador, have a better chance at fighting various health conditions and disorders than purebred dogs.

However, the best way to determine the potential health issues is to ask your breeder if the purebred parents to your puppy suffered from any health problems.

Generally, Mastiff Lab Mix dogs are susceptible to ear infections, especially if they are not cleaned regularly. Also, lack of regular teeth cleaning can lead to gum infections. Your Mastador dog’s coat may also produce a funky odor due to the build-up of pet dander.

However, with the right diet, one that is low in calories and fats, your dog can maintain a perfectly healthy heart and body no matter his age.

Buying your Mastiff Lab Mix puppy from a reputable breeder and requesting to check the health certificates can be a great way to reduce those risks.

Despite being a mixed breed, Mastadors can suffer from the above genetic diseases and therefore, it is important to ensure that both the parent dogs are thoroughly tested for various genetic disorders.

The Mastiff parent should have health clearances for eye problems, heart disorders and skin infections. Ideally, the Mastiff parent should also be checked for hip dysplasia.

The Labrador Retriever parent must have no record of eye problems, hip and elbow dysplasia.
