Mastiff Breed Information and Personality Traits 

Regardless of the type of breed, most households across the world have a pet. Because they are considered companions, these animals become significant in the lives of many individuals. Oftentimes, people love their dogs more than they love others. 

As a pet, the dog is one of the most popular animal species. Because of their dedication and affection, these creatures are considered man’s best companions. Canines aren’t all the same.

There are a variety of breeds with various talents and physical qualities. The Mastiff is one of the most intriguing, especially because of its size and physical look. 

The Mastiff is a dog breed that is distinguished by its size and powerful, muscular build. It is a canine with exceptional strength and resistance, allowing it to serve as an effective watchdog.

Despite these traits, it has a gentle and peaceful disposition, which enables it to be friendly and submissive to its loved ones. Because the Mastiff is not the smartest dog, it must be trained since it is a puppy. 

It is a breed that is incredibly protective and peaceful, as well as being very loving and brave. It does not strike out as having a high level of intellect because it generally acts on instinct and is clumsy.

How to Groom a Mastiff at Home? 

Mastiffs are one of the simplest dogs to groom, and they won’t want for much from you other than tenderness, love, and attention. The Mastiff will shed all year, but less during the winter months. Your dog’s fur thickens throughout the autumn and winter to shield it from the elements. 

You have to brush your Mastiff each day, or every few days, according to some specialists. The objective is to ensure that the short coat of your Mastiff is clear of skin cells and dead hair.

Mastiffs shed throughout the year, so unless there’s an exceptional lot of fur falling off, you shouldn’t be concerned. Brushing them on a regular basis is always preferable to not brushing them at all. It will keep the fur and skin of your Mastiff healthier, resulting in reduced shedding. 

Bath time is a difficult situation since your Mastiff will either enjoy or despise it. Most Mastiffs appreciate water and enjoy playing with it, but certain dogs, like some children, will always dislike bath time. During high shedding periods, many groomers advocate more regular bathing. 

After bathing, the following step will be to paint your nails. Before you cut your dog’s nails, make sure they’re completely dry. Wet nails are harder to trim, and unclean nails will impede your clippers while you’re working. Similarly, you should strive to keep your dog’s ears clean since infections might develop if they spend too much time dirty. 

Are Mastiffs Hypoallergenic? 

Mastiffs are not a hypoallergenic breed. If you have ever had dog hair allergies, you should avoid getting a Mastiff. Your Mastiff is likely to aggravate these allergies to the point it could no longer live with you. 

Even dogs with little to no shedding may never be called “100% hypoallergenic,” and the Mastiff is certainly not one of them. Their short hair may deceive owners into believing they do not shed; however, this is not the case. 

The fact that these canines continue to produce dander, whether through urine, sweat, saliva, or hair, is the major reason they are not hypoallergenic. There is no exception when it comes to the Mastiff. Their urine, saliva, fur, and sweat are not the true culprits.

These are only some of the most popular elements where the Fel D1 may be found. This protein is the main allergen that is thought to protect the skin of dogs, although further research is needed to confirm this. 

How Much Exercise Does a Mastiff Need? 

How Much Exercise Does a Mastiff Need

As a huge breed, it’s critical that they don’t get too much activity, thus walks should be moderate and short. Mastiffs require frequent moderate exercise for the first 20 months of their lives.

That implies we shouldn’t give it exercises that put too much strain on its joints. To preserve joints, 10-20 minute daily walks with modest running may be enough for an adult Mastiff. 

When bringing your Mastiff for a walk, keep in mind that they can rapidly overheat and, owing to their size, will not like extended running sessions. Understanding what type of exercise Mastiffs require as puppies and adults are critical to their overall health and happiness. 

How Long Do Mastiff Dogs Live? 

The average life expectancy of a Mastiff varies between 6 and 12 years. It should be noted that said time will depend on certain factors such as diet, physical activity, mental stimulation, genetics, and quality of life in general. 

Is Mastiff a Good Family Dog? 

When it comes to having a dog, particularly a Mastiff, there are a few things to keep in mind. This dog breed is good for families in general. Nevertheless, we must remember that not all individuals are the same, and the Mastiff may not be the right option for some of them. 

The Mastiff is a brave but gentle breed that makes an ideal family pet. Mastiffs are kind to older children, but because of their size, they should be supervised around small children. 

When guests come to the house, the Mastiff’s guard dog nature is likely to come to light. Outsiders make this canine wary, and it is protective of its people and territory. 

When is Mastiff Full Grown? 

A full-grown Mastiff male weighs 72 kg to 100 kg on average, while a female one weighs 54 kg to 77 kg. 

Around the age of 1 year, many dogs of this breed will have reached adult height. Mastiff pups, on the other hand, need 2 to 3 years to fully mature. Giant breeds of dogs, unlike tiny and medium-sized canines, might take years to mature. 

There are various factors for estimating the mature size of a Mastiff: 

  • Age: They are probably close to their final size in general if they are already 2 years old. If your pup is just 6 months old, though, it still has a lot of developing to accomplish. 
  • Gender: The gender of a puppy has a big impact on how much it weighs and how tall it grows up to be. Giant dog breeds, such as the Mastiff, show significant weight discrepancies between male and female dogs. 
  • Paw size:  If your puppy’s paws appear disproportionately large in comparison to their legs and torso, it’s likely because they’re still growing. If your pup’s paws don’t appear to be enormous, they may already be near to their full size. 

Do Mastiff Dogs Shed? 

Mastiffs have a double coat and shed somewhat throughout the year. Their dense undercoat and short, straight outer coat, on the other hand, shed more profusely once or twice per year as the seasons change. Although you cannot stop a Mastiff from shedding, frequent brushing may considerably minimize it. 

Mastiffs shed dead or damaged hair to replace it with a new, healthy one, much like other types of dogs. There are three stages to this cycle: 

  • Anagen: The period during which your dog’s fur is growing. 
  • Catagen: This is the shortest phase, lasting only around 10 days. Your dog’s hair does not grow or fall throughout this period. 
  • Telogen: This is the time when the hair starts to fall out. 

Canines shed to adjust their fur to the changing temperatures and climates of the seasons, in addition to discarding old hair so that new ones can grow. Mastiffs, on the other hand, shed all year, with the most significant shedding occurring between summer and autumn. 

When to Bathe a Mastiff? 

Depending on its level of physical activity and lifestyle in general, this friendly canine can be washed weekly to every 6 to 8 weeks. Bathing is necessary for this short-haired, dense-coated breed to decrease shedding and preserve a healthy coat and skin. 

Before washing, run over the body of the Mastiff with a high-velocity dryer to remove any loose hair and loosen any debris and dirt from this thick fur. 

Should Mastiffs Be Shaved? 

Depending on their coat type, many canines must not be shaved at all. In fact, having could have the reverse effect and make your pet even warmer. 

Shaving shorter-haired breeds, such as the Mastiff, must be avoided. This is due to the fact that it is detrimental to these dogs, and they are also at risk of sunburn if they are shaved. Sunburn may happen to any canine; therefore, if you shave your short-haired dog, leave at least an inch of hair to protect it from the sun’s rays. 

Hair has a number of metabolic, thermoregulatory, sensory, and defensive activities that all contribute to your pet’s general health. These are the following: 

  • It helps your pet’s natural fats to be balanced. 
  • When it rains, the animal’s fur protects its skin. 
  • It protects your canine from insects. 
  • It maintains the skin of the dog healthy and free of infections and dermatitis. 
  • It protects it from both extremes of heat and cold. 

Can Mastiffs Be Service Dogs?    

Can Mastiffs Be Service Dogs

Service dogs are animals that have been trained and integrated into a multidisciplinary team of health and education specialists to assist patients in improving interpersonal and social contact while also physically and psychologically engaging them. Simply said, service dogs are specially trained to assist individuals with impairments. 

They are excellent mobility dogs due to their size, but they also make excellent service dogs for persons with PTSD, mental difficulties, depression, and anxiety, and they are extremely gentle with and watchful of tiny children. 

Alerting and defending an individual having a seizure, alerting people who are deaf, pulling a wheelchair, guiding blind people, relaxing an individual with PTSD (Post Traumatic Stress Disorder) during an emotional breakdown, trying to remind a person with mental illness to take prescribed drugs, and so on are some of the tasks that the Mastiff can perform. 

How Do Mastiffs Show Affection?  

Some dog breeds are less loyal and loving toward their owners than others. Mastiffs are friendly and tranquil, especially with their owners and human family members, including children (not so young).

Still, despite their size, they can get along with strangers if socialization training is provided. It should also be highlighted that they will be quite protective of their loved ones since they care about their well-being. 

Dogs, on the whole, have personalities that are comparable to our own. It’s worth noting that some dogs are friendly and loving, while others are aloof and self-sufficient. 

Mastiffs are devoted companions and like being in the company of their humans. As a result, they show their affection by: 

Mastiffs Jumping on You 

Even though most owners train their dogs not to jump, it is a common way for them to express affection. It’s a method for them to tell how much they’ve missed you and how happy they are to see you again. However, keep in mind that these dogs are very large, so you should be careful when your dog tries to jump on you or your children. 

Mastiffs Sniffing You a Lot 

The Mastiffs’ sniffs might indicate devotion and love for their owners. This shows that they care about you and want to spend time with you. 

Mastiffs Staring into Your Eyes 

One of the ways the Mastiff communicates care for you have been demonstrated to be by staring into your eyes. When dogs do this, a hormone called oxytocin is produced, which aids in the formation of deep bonds between the animal and its owner. 

Mastiffs Wiggling Their Bottom 

Mastiffs wag their tails and jiggle their butts when they are enthusiastic. They do this to demonstrate how they feel about you and how much they care. 

Mastiffs Follow You 

A dog that has been left alone for a lengthy period of time will not feel happy. Mastiffs like spending time with their owners and other members of their household, like a lot of dogs.

You will observe your Mastiff following you because it wants to be near you and spend time with you. It is not the most common display of affection in these dogs, but it could happen. 

Mastiffs Licking You 

Mastiffs, like any other dog, express affection and love by licking. Although not all Mastiffs behave in this manner, it is a wonderful way for them to show their affection. It’s important to remember that your dog will drench you in saliva, so be ready. 

Can My Mastiff Dog Live in Hot Weather? 

Mastiffs have thick hair and lose their upper coat once a year at the very least. This shedding occurs before the development of a new undercoat, which is made up of finer, warmer hair. 

They basically have a lot of hair and can be really hot. If they are raised in a warmer environment from puppyhood, they may thrive in it. However, they do better when they live indoors and only go outside for short periods of time to exercise. During the hotter months, they will need air conditioning to stay cool. 

They must not spend extended periods of time outside during the summer. You should supervise your Mastiff while walking or exercising outdoors at 70-78 ° F.  Temperatures higher than this could be life-threatening. 

Thins you need to keep your Mastiff cool in hot weather: 

  • Water containers 
  • Dampened towels 
  • Physical activity at the appropriate time of day 
  • Walking on not-so-hot surfaces 
  • Spending time outside when there is no extreme sun. 

Can Mastiffs Live Outside? 

Can Mastiffs Live Outside

No. Despite their sturdy and muscular build, Mastiffs are not designed to live outside full-time. Long-term outdoor life has been proved to have negative psychological and physical effects on dogs, particularly Mastiffs, according to some studies. Behavior difficulties, such as emotional instability and increased hostility, are among the side effects. 

Mastiffs’ extremely sensitive temperament, according to researchers, makes them quickly upset. Mastiffs are a sociable breed; thus, they should not be left alone for lengthy periods of time. They require the company of people or, at the very least, other animals. They also require standard interior amenities like comfy beds and clean feeding spots. 

Build or purchase a dog house for your Mastiff if you want to let it out for lengthy periods of time. Mastiffs are territorial dogs, and while they are unlikely to run away, you should fence your garden or yard. 

Can Mastiffs Swim? 

If well-trained and introduced to swimming from an early age, Mastiffs could swim. Nevertheless, due to their massive body and form, many Mastiffs will keep struggling in the water. Teaching them to maneuver across the water using their webbed paws as oars may help them become more competent. 

These canines are brachycephalic, which means their snouts are shortened, and their faces are practically flat. They typically struggle to breathe in the water since they have respiratory problems. 

Although Mastiffs have a hard time swimming, it doesn’t mean they don’t like to swim. Some of them love to swim at beaches, pools or lakes. However, as you might expect, most will hate swimming due to the difficulties it presents. 

To teach water-averse canines, such as the Mastiff, to swim, you should always keep safety in mind. Always keep an eye on your pet in case it becomes exhausted and has to be rescued. You must consider the following: 

Allowing your Mastiff to enter waters too deep for it is not a good idea. 

Wherever you go, maintain your Bullmastiff towards the shallow end of the water. 

In case you have a pool in your home, it’s an excellent idea to encircle it with a fence to keep your dog away. 

Should I Neuter My Mastiff? 

While opinions differ, most veterinarians agree that your Mastiff should be spayed or neutered between the ages of 4 and 9 months. There are a number of reasons for such a long period of time, and some veterinarians feel that depending on your Mastiff’s sex, that timing may have a positive influence on their behavior. 

After your male Mastiff reaches adolescence, it is typically suggested that you neuter it. That is believed to provide long-term health benefits as well as aid in the avoidance of behavioral traits like marking and aggression. There is no hard and fast rule when it comes to when female Mastiffs must be spayed.  

Some specialists recommend spaying before the first heat, while others say it raises the risk of breast cancer. A particular assessment from your veterinarian is always recommended. 

Spaying and castration, according to some studies, may help canines live longer and have fewer troubles later in life. Males with castration have a decreased risk of prostate and testicular cancer. 

Can Mastiffs Be Left Alone? 

Can Mastiffs Be Left Alone

In general, you should only leave your Mastiff alone for 4 hours. Because each canine has varied levels of social requirements, this will vary from one dog to another. Some animals of this type have been taught to live alone at home, while others still find it difficult to spend the day alone. 

If it feels bored on a regular basis and nothing is done about it, indications and symptoms of anxiousness will emerge. 

Boredom and being alone for long periods of time might irritate your Mastiff. You must understand that these dogs know how it feels to miss someone, particularly those to whom it is most devoted. This kind of living might be harmful to your Mastiff’s emotional and physical health. The following symptoms may occur as a result of this: 

  • Unresponsiveness 
  • Stress 
  • Anxiety 
  • Depression 
  • Lots of sleep 
  • Destructive behavior (howling and barking for no reason, chewing on furniture, etc.) 

The number of hours a Mastiff can stay home alone will depend on its age: 

  • Under 10 weeks: 1 hour 
  • Between 10 and 12 weeks: 2 hours 
  • Between 3 and 5 months: 3 hours 
  • 6 months or more: Between 4 and 6 hours 

You can leave your dog with one of your family members while you go to work if you live with numerous relatives. Similarly, you can seek the support of a neighbor to look after your Mastiff while you are away; however, this is not suggested if you work every day. 

Are Mastiffs Good with Cats?  

Some Mastiffs get along with cats, while others despise them. Mastiffs, like all dogs, retain some of the hunting behavioral tendencies for which they were originally bred. This is why Mastiffs enjoy chasing after anything that moves, whether it’s a toy, a car, a rat, or a cat. 

Given that many felines will flee if they come into contact, it’s easy to understand why they are known for not getting along. Mastiffs like pursuing cats, not because they detest them, but because a fast-running animal activates a tremendous, innate instinct to chase that outweighs any training or socialization. 

It takes time, patience, and persistence to educate your Mastiff to stop pursuing cats, but the reward of not having to worry about them continually chasing is well worth it. A variety of factors will influence your Mastiff and cat’s ability to live together.

The most important factors are socialization training, attention span, and engagement between the two when playing or exercising. All of these elements have a significant impact on the interactions between the two species. 

Do Mastiffs Like to Cuddle? 

Mastiffs do enjoy cuddling. Licking hands, gently gripping, snuggling, back rubs, sleeping with their master and other cuddly behaviors demonstrate their fondness and cuteness.  

Cuddling behavior could be improved by paying more attention to them and, in some cases, through education. 

Cuddling time can be long or short based on your pet’s environment and physical and mental health. Mastiffs are fantastic for cuddling family members if their demands are addressed. The following are some suggestions for promoting and increasing cuddling time with your pet: 

  • Go for a walk with it 
  • Recognizing its moods 
  • Make sure it has adequate nutrition 
  • Grooming 
  • Give it a gentle rub every now and then 

Are Mastiffs Aggressive? 

Mastiffs are not naturally aggressive, but they might turn aggressive if they are not properly socialized, trained, or handled. As a result of their massive size, such characteristics might make them one of the most aggressive types of canines.

Mastiffs, however, are kind, loving, and patient by nature, and they can just absorb what you teach them, which is why education and proper dog management can make a significant difference in your pet’s demeanor and disposition. 

It should be noted that although it is not very common, aggressive behavior in these dogs can be triggered due to certain factors such as food, lack of socialization with other dogs or people, etc.

In fact, Mastiffs hostility towards dogs is the most common form of aggression that they can present, so it is important that they are trained from puppies to avoid that. 

Are Mastiffs Good with Kids? 

They get along well with kids and other animals, and they enjoy getting their fair amount of attention. Mastiffs could be a great addition to your household if you give them a great space to run around in and play with them frequently.

That is due to their extreme friendliness with their owners and the majority of other individuals. They’re known for being gentle giants, which is why they’re so popular among pet owners. 

The only thing to consider is that some Mastiffs could be violent if they were neglected as puppies. This violence is a result of their desire to bond with their owners. Thus it’s mostly despair and bewilderment. They become enraged, resulting in unreasonable behavior. This could put kids, especially young ones, at risk. 

In addition to the possible aggressive behavior, we also have to highlight the immense size of this dog. Although the Mastiff is an affectionate and friendly dog with its loved ones, including children, we also have to clarify that its large size could be a factor to take into account when they are playing with children.

They could push and hurt (unintentionally) a small child as these canines could get carried away by the emotion of the moment. 

Are Mastiffs Good with Other Dogs? 

Mastiffs are possessive canines. They will keep dogs and people out of their yard, house, and family. They are animals that could get along with other canines if they have had previous positive experiences with them.

If you currently have an adult male Mastiff and wish to get another, a female Mastiff can be a good choice. This isn’t to imply that two males of this breed can’t get along, but males, especially those who have just been neutered, have a strong desire to control each other. 

The Mastiff has the potential to be aggressive toward other dogs. This is primarily due to inept dog ownership. Each Mastiff pup must spend at least eight weeks with its mother. It can communicate with its siblings because it is in a litter. That is the first time it has been exposed to other dogs. 

It is critical to remember that after the Mastiff has received all of its vaccines, Mastiff owners should allow their puppies to be exposed to a variety of locations, persons, and animals throughout their first 8 to 16 weeks of life. That is to supplement the socialization it received from its littermates. 

Mastiff Dog Diet 

The nutritional needs of a Mastiff puppy alter rapidly over the first 2 years of its life and then stabilize once the dog reaches adulthood. The diet of each Mastiff varies based on their size, age, sex, personality, and metabolism. 

Mastiffs, like other canines, require a balanced diet of minerals, protein, amino acids, lipids, and fatty acids in order to have a healthy weight and body shape.

Mastiff diets are primarily meat-based, with both protein and fat coming from human-grade sources. Carbohydrates must make up the third half of a Mastiff’s diet, as they will provide it with the calories and energy it requires. 

If you’re going to feed your Mastiff pet food, make sure it has at least 3 animal proteins in it. These components should come first on the ingredient list, and they must ideally come from lamb, fish, chicken, or beef. Simultaneously, you should stay away from any store-bought goods that include artificial dyes or chemicals. 

While fibers are necessary for your dog’s digestive system to work properly, a meal that contains more than 5% of them might be harmful to their health.

Furthermore, some owners prefer not to offer grain-based fibers to their Mastiffs because these elements might induce allergic reactions in susceptible breeds. Introduce starchy veggies, such as peas, as an additional source of fiber that does not include grains. 

It’s also critical to give your Mastiff enough Omega-3-rich foods. Whether you give your canine salmon or simply give it Omega-3 pills, such chemicals could help maintain the health of its skin and coat. 

Along with what we’ve mentioned above, it’s essential to supplement your Mastiff’s food with vegetables, fruits, and even eggs.

Eggs are excellent because they include many proteins and minerals, but it is important that we do not feed our canine raw eggs. The best way to ensure that your dog can digest it is to fry or boil it. On the other hand, fruits and vegetables are frequently utilized as healthy treats for this breed of dog. 

Are Mastiffs Good for First Time Owners? 

Are Mastiffs Good for First Time Owners

If you’re acquiring a dog for the first time, you’ll almost certainly be researching different breeds to find the one that best suits your needs. As you may be aware, there are a variety of dog breeds, each having distinctive characteristics that distinguish them from one another. 

Many people ask if this is a good breed for first-time dog owners. Really, this dog might not be a good choice for first-time owners.

Although these canines are very friendly with each member of their human family, it is important to take into account a super important aspect which is their large size. Generally, a first-time dog owner should never acquire a large breed like his first dog as he will not be able to control it properly. 

Also, these dogs can be challenging to train, and that could cause a lot of problems for a first-time dog owner. 

Are Mastiffs Smart Dogs? 

Mastiffs can be intelligent; however, it depends on the dog. During puppyhood, this breed develops into a curious pet who will display nosiness and curiosity in every interesting situation. 

Some owners, on the other hand, wonder how intelligent these canines are. According to several Mastiff owners, these enormous dogs are extremely stubborn. 

The Mastiff has the lowest level of intelligence when it comes to working and obedience. It is ranked in the same position as the Beagle, which is ranked 72nd.

According to Coren’s research, the Mastiff needed 80 to 100 repetitions or more to properly grasp what had been taught, and its level of obedience on the first command is 25% lower. 

When Do Mastiffs Calm Down? 

Mastiffs mature approximately up to 2 years to reach their full size. From then on, the Mastiff may begin to calm down, although this may depend on several factors such as age, size, personality, amount of daily exercise, and general lifestyle. 

It’s crucial to keep in mind that not all Mastiffs are created equal. Some of these dogs will become less hyperactive after they hit the age of two, while others may continue to be energetic after that. The truth is that there are a number of strategies for keeping our Mastiff calm, but first, we must provide it with a beautiful lifestyle. 

Will Mastiffs Run Away? 

Will Mastiffs Run Away

A Mastiff dog does not generally run away because it is an animal that is deeply attached to its owner. They must spend the majority of their time with their loved ones; else, they will become sad and anxious. 

This leads us to assume that a dog of this breed is unlikely to flee. People may feel their Mastiff is running away when they take it on a walk and observe it chasing after other canines, but this is not the case.

This kind of dog is recognized for being friendly to everyone in its habitat, including other animals, as we all know. It’s natural for your Mastiff to try to socialize with other dogs in these situations. 

How Much Do You Feed Your Mastiff? 

Every day, most full-grown Mastiffs consume 6-10 cups of dry food. The precise amount of food for your pet will be determined by the sort of food and your canine’s characteristics.

To fully develop, all growing pups will require high-quality food. Don’t give your puppy adult pet food since it lacks the nutrients that a Mastiff puppy requires during its development. 

The amount of food your Mastiff puppy should receive on a daily basis depends on its age: 

  • Between 8 and 12 weeks: 2 to 4 cups 
  • Between 3-4 months: 3 to 6 cups 
  • Between 5-6 months: 5 to 8 cups 
  • Between 7-10 months: 6 to 9 cups 
  • 11 months and up: 6 to 10 cups 

Adult male Mastiffs must eat between 8 and 10 cups each day, while female Mastiffs should consume between 7 and 9 cups. Of course, this quantity can be divided into two or three meals.

To avoid bloating, do not provide it with all of this food at once. In the case of a neutered Mastiff, the male of this breed should be fed 6 to 7 cups per day while the female 7 to 8 cups per day. 


The Mastiff is a big dog breed that requires a lot of space, food, companionship, and affection. Its family must have prior experience with energetic canines and be willing to be harsh with it when necessary. Mellow, mild, and novice owners would undoubtedly struggle with this massive breed of dog. 

It should be noted that although Mastiffs can be affectionate and friendly with people, they could develop aggressive behavior, especially with other dogs, if they do not receive socialization training.
