English Mastiff Lab Mix 101 (2)Who wouldn’t want a great family dog? As dog owners, we all try to create a safe and comfortable environment for our dogs who are part of our family. But this can’t happen without a good dog with a calm nature and a submissive personality that will respond to training and be eager to please. This is where the English Mastiff Lab mix comes in; a mixed breed dog that may seem intimidating at first but is actually a friendly breed that will love their family.  

What is the English Mastiff Lab Mix? 

The Lab Mastiff mix is an extremely friendly breed and is also highly intelligent, which can make them lovable family members. Because they’re the offspring of the Labrador Retriever and the English Mastiff, they will inherit some traits and characteristics from their parents. However, you can’t expect them to behave exactly like a Labrador would and they won’t be as easy to train. 

While they are smart dogs that are sensitive to your wants and needs, they can also get bored easily and won’t do well with long training sessions. However, before we expand more on these dogs, it’s best to understand where they came from.  

History of the English Mastiff Lab Mix 

We all know the Labrador Retriever is among the most popular dog breeds in the world; according to the American Kennel Club, it is currently the 2nd most popular breed today. These dogs were originally developed in England using dogs imported from Canada where they served to retrieve game from both land and water. On the other hand, the term “Mastiff” is actually a group of dogs that have existed for the last 3,000 years with similar characteristics.  

However, when people speak about Mastiffs, they usually refer to the English Mastiff which is a large breed of dog used for hunting and guard work. In recent times, these dogs have been used for blood sports as a result of their large size and were pitted against big wild animals. But contrary to popular belief, they’re not naturally aggressive dogs and are actually loving and friendly with their family. 

Mastadors are among the various designer dog breeds that were developed in the United States to minimize the health concerns that often come with purebred dogs. Even if these dogs haven’t been around for too long, you can be sure that their parents’ extensive background will be passed on to their offspring. Below are just a few traits and characteristics that you can expect these dogs to have.     

English Mastiff Lab Mix Appearance

This large dog breed is no joke; they can grow between 38 to 36 inches tall at the shoulders and will weigh between 86 to 160 pounds! While the Labrador is already medium to large in size, Mastiffs can grow even bigger and will produce huge offspring. Most of the time, the Mastiff will be the mother to accommodate the bigger puppy while the smaller Labrador will often be the father. 

Your Mastador will also come with a broad head that may have a black mask and a stocky body which is common in both parent breeds. Their offspring can inherit the flat nose of a Mastiff or the longer nose of a Labrador but they will always get floppy ears that come down on the sides of their face. The Labrador is known for its short, double coat that protects them against water but they will also shed quite a bit. 

On the other hand, the Mastiff comes with a dense, short, and silky coat that won’t shed as much as a Lab’s but there’s no guarantee that their offspring will take up after their Mastiff parent. Luckily, inheriting a denser and shorter coat is more common but they will still need to be brushed twice each week to eliminate loose hair and to minimize the irritations and issues caused by shedding. 

There are various colors that the Mastador can come in such as brown, black, yellow, or brindle which can also come in solid colors or a mixed coat. While the size of their heads can make them look dangerous and imposing, this doesn’t reflect their personalities. As such, many dog lovers refer to this dog as a gentle giant that can get along with everyone, even children, provided that they get early socialization. 

English Mastiff Lab Mix Temperament 

This designer breed will inherit its temperament from both of its parents. Labrador Retrievers are known to be intelligent dogs that are eager to please and are often easy to train. They’re also known to be highly affectionate and very friendly, even with small animals. While Mastiffs also have high intelligence, they can be lazy at times and may easily get bored. 

Much like Labradors, the Mastiff is a loving and affectionate dog that loves being around people; while they can get along with other dogs, smaller dogs may be at risk since they have a high prey drive. While they also love kids, their big bodies can cause potential accidents, so proper training is a must. Mastiffs will often be wary and aloof around strangers which is why they can be good guard dogs and will often be left at home to protect their owners’ property.  

While it’s not possible to predict the kind of personality that your Mastiff Labrador mix may have, there are still a few things you can expect the puppies to inherit from their parents. Generally, the Mastador temperament will include a calm demeanor that makes it friendly and will often be a great companion to its family. These dogs will want to be part of their family which means they will want to take part in the action inside the house rather than being left outside. 

Despite their potentially excellent temperaments, they will not be happy when left alone for a long time and they may develop separation anxiety. Even so, both dogs have a protective nature and can be taught good behavior through training, though this can be difficult when using traditional methods. Moreover, they can be sensitive and are highly skilled at reading body language and facial expressions so make sure never to punish them during training to prevent adverse effects.    

English Mastiff Lab Mix Care

While the Mastador has the potential to become the best dog for you and your family, it’s up to us as their parents to give them the best care possible by following the guidelines outlined. 


Due to their large size, the Mastador will need a diet that’s specifically formulated for large breeds which means it needs to have high amounts of fat and animal-based proteins. Mastadors may also be prone to skeletal disorders such as bone cancer, so they will need to be given the right phosphorus-to-calcium ratio to promote healthy bones. Be sure to visit our post on the best dry dog food to get an idea of a suitable choice for your new pup.  

However, it’s also important to give your dog a balanced diet; to do this, you’ll need to watch what your pooch eats while controlling their calorie intake. Unfortunately, these dogs will keep eating even when they’re full, which means that it will be easy for them to eat more than they’re supposed to. While there’s no way to feed your dog the exact amount it needs, you should keep an eye on your dog to help determine how much food they need to maintain their energy levels and weight. 

However, as a general rule, puppies will need to eat more than adults since their body needs more fuel and energy to support their growth and development. Depending on how active your dog is, you can feed it 3 to 3 ½ cups of dry dog food every day which should be split into two meals to give it energy. These dogs will need to be fed slowly to protect them from bloat — finally, be sure to set aside some money for their high-quality meals. 


One of the great things about these lab mixes is that they won’t need heavy grooming; their naturally smooth coats are low maintenance and will only need regular brushing to keep them looking neat. Brushing them will help to spread their natural oils over their coat while removing the loose hairs will promote hair growth. Unfortunately, these dogs aren’t hypoallergenic, so it’s best to vacuum your home once a week to keep your home clean. 

Bathing these dogs can be a challenge as a result of their large size and it can be time-consuming; because they’re so big, it’s best to shower them in the backyard with a water hose. Whenever possible, you may want to take them to a professional groomer where they have a designated facility to bathe larger breeds. You might also want to take your pup out for a swim or splash around in the water which should be enough to keep your pooch clean and fresh. 

While a monthly bath should be enough for these Mastiff mix breeds it’s important to clean their ears weekly to prevent infections. Since they have floppy ears, they’re more vulnerable to infections and wax build-up so be sure to check their ears regularly. It’s also important to trim their nails and brush their teeth to ensure good oral health and healthy nails.


Because Labrador Retrievers come with such high energy levels, they will need plenty of regular exercise but as adult dogs, they will need a minimum of an hour per day. They will also need a lot of space to move around whenever they’re at home but the Mastiff in them can be quite lazy and they won’t need much exercise. If your dog is perfectly blended between both parents, it will be happy to go out for a two-mile walk on a daily basis. 

Due to their size, they will need plenty of space where they can take naps; they won’t push themselves to exercise if they feel too tired and will likely lie down to rest in the middle of walking. Your pooch may land somewhere in between these two kinds but this will vary depending on each individual dog. Be sure to monitor these big dogs to understand exactly how much energy they have and what their exercise needs will be. 

These dogs won’t be afraid to tell you when they’re tired, so make sure to break your exercise sessions into two shorter sessions and try not to over-exercise them while they’re still puppies. Your Mastador puppy should get around 5 minutes of exercise each day for every month of age; for instance, a 4-month-old pup will need 20 minutes, and a 6-month-old dog will need 30 minutes per day. Keep in mind that Mastadors are often considered to be puppies until they reach the age of 2 years old.  


When it comes to training large breed dogs such as the Mastador, it’s best to stick with short training sessions; these sensitive dogs should never be punished since it can lead them to rebel and refuse to learn. When mishandled, these canines can become fearful, shy, or aggressive, but will learn particularly well through positive reinforcement. Make sure to start training and socializing them at a young age, exposing them to as many different people, animals, environments, and situations as possible. 

But don’t forget that it’s imperative that you teach them commands such as “sit” and “stop” to help keep them under control during stressful situations. Because these big puppies have the natural desire to protect their humans, it can get scary for people who aren’t aware that your pooch is a gentle soul. These big dogs will need to be given slow, consistent, and gentle training so you will need to set the boundaries early to help contain their strength. 

Through reward-based training such as small treats and praise, your Mastador should be able to learn all you need it to. Below are just a few things you can get started on with your new canine companion if you don’t plan on getting a professional trainer. 

  • Basic Commands: Make sure to develop basic commands such as Sit, Stop, Down, and Stay while being consistent every time you see your pup. Because of their large size, they will tend to dominate if not controlled during early training. 
  • Crate Training: Purchase a crate early on and ease in your puppy to help it get used to using a crate. This should become its place for rest; you will need to lock the crate at first to help it understand it will be sleeping there. 
  • Potty Training: This can be a hit or miss with new puppies since they can be excitable and may lack control, but there are many products you can use to help them learn quickly with fewer mistakes. Eventually, your pup should learn where it can and can’t go and will become a creature of habit that knows when and where to go for a potty break. 
  • Leash Training: Train your puppy to walk on a leash when outside. This will teach your pup to be aware of their surroundings and is an important part of safety training. 

English Mastiff Lab Mix Health Problems

Like all large breed dogs, the Mastador comes with a life expectancy of 10 to 12 years, and they generally enjoy good health. But much like others, this breed of dog may still carry some kind of genetic disease over to its offspring, which we discuss in detail. One of the reasons why designer breeds were created was to try and minimize the different health conditions that can be inherited by their pups. 

While this means that your new puppy may be less likely to be born with a hereditary disease, there are others that may appear as a result of having two different parents. Moreover, some parent breeds may share the same health conditions which could present a higher risk for your pup. Some of these health issues include skeletal conditions such as elbow and hip dysplasia, which are common in large and giant dog breeds. 

Eye problems such as cataracts and retinal dysplasia may occur in these dogs — weight gain and bloat are other problems that they can encounter, so a proper diet is a must. While bloat may not sound like a serious problem, it can become fatal for dogs if not treated correctly. As such, regular veterinary check-ups are vital and should be part of your dog’s routine to maintain its overall health. 

English Mastiff Lab Mix with Other Pets and Children

While Mastadors absolutely adore children, they’re not the best best to have around them especially because they can be a lot to handle for small children. If your children aren’t used to dogs, they can easily get scared or mishandle these dogs which can result in canine trauma. Moreover, their gargantuan size means that a simple whip of their tail could hurt small kids. 

While they will generally get along well with dogs of a similar size, their hunting instincts may lead them to chase smaller animals such as cats. 

Finding Your English Mastiff Lab Mix

It’s never a good idea to purchase from puppy mills and farms because dogs will be inhumanely bred in these places just for a quick buck. Instead, you should look for Mastador puppies from rescue organizations or from animal shelters where these dogs will get the care and attention they deserve. Buying dogs online isn’t such a good idea either since you’ll never know where they came from or the kind of treatment and care they were given. 

The best way to get your dog is to meet it personally, face to face, and upfront so you can ask all the questions you might have about the dog’s background and upbringing. Remember that taking a dog home from a shelter is also very fulfilling since you’ll be saving the life of a puppy and giving it a place to call home. You won’t forget the smile on their face once you make them feel a valued and welcome part of your family. 

Purchasing an English Mastiff Lab Mix

If you’d rather purchase one of these pups, be sure to speak to responsible Mastador breeders who will be able to answer all your questions and tell you about the dog’s background. Because these English Mastiff and Lab puppies will cost around $800 to $2000, you’ll want to make sure that your money is going towards a quality pooch. This price will vary according to the age, health, and location of the puppy along with the demand for these puppies and the breeder’s reputation. 

However, finding a responsible breeder isn’t always easy so be sure to do your research and perform your due diligence first before making a deal for one of these wonderful companions. As mentioned, be sure to meet with the breeder personally and ask for proof of health such as a health certificate, and ask about the puppy’s parents. A good breeder will warn you of any potentially inherited genetic diseases from the puppy’s parents. 


The English Mastiff Lab mix is a terrific mixed-breed dog that comes with the large body of the Mastiff and the social qualities of the Lab which make it so friendly and lovable. When given a healthy diet, regular exercise, and proper care, they can easily thrive in homes with a big enough room for them to play and move around in. When trained correctly, they can become great guard dogs and will serve their family in the best way they can while keeping them safe at all times.
