The mastiff is known for its large size, friendliness, loyalty, and affectionate nature.

There are several breeds of mastiffs including the Bull, English, Italian, Neapolitan, French, and Tibetan mastiffs. Though the color and appearance of the various breeds differ a little, they all share the same gentle temperament making this an ideal family dog.

Tibetan Mastiff

The Tibetan mastiff has a heavy coat with a “lions mane” around its magnifcent head.

The Tibetan mastiff stands out the most from its cousins. It has a heavy coat with hair around its head that looks similar to a lion’s mane. It needs a more extensive grooming routine than other mastiffs.

The mastiff breed dates all the way back to ancient Rome and Egypt. Back in 55 BC, they were owned by many people in noble families. They were used as guard dogs because of their courage and intimidating appearance.

Mastiffs are part of the working group of dogs. They are smart, sensitive, and gentle. A family looking for a large, sweet addition to their household may find a mastiff to be the perfect fit!

Evolution

While there are different types of Mastiff, they can all trace their origins to ancient civilizations in Egypt and Rome. It is said that Caesar described a mastiff in his accounts of invading Britain in 55 B.C.

Mastiffs were bred to be guard and fighting dogs and were frequently pitted against bears, bulls, lions, tigers and human gladiators in ancient Rome. Their bravery paired with brute strength and an imposing manner made them a favorite of the Romans. Breeders all over the world developed types to suit regional needs and preferences – but they all exhibit the same dignified strength, massive size and kind manner toward their families.

Types of Mastiff

  • Bull Mastiff: A cross between an English mastiff and an Old English Bulldog, the Bull mastiff was bred in the 19th century to be the ultimate guard dog. Not quite as big as other mastiffs, the Bull still gets up to 130 pounds. With intelligent, dark eyes and the classic mastiff broad head, this dog shares the kind disposition toward its family of the other mastiffs.
  • English Mastiff: Also known as the Mastiff, this colossal canine is strong and courageous while also sweet and dignified. Even though they are so huge, their giant broad head with wrinkled brow and masked muzzle features a kind expression.
  • Italian Mastiff: Also known as the Cane Corso, this massive mastiff can trace its orgins to ancient Rome, where it was known as the bodyguard dog. These dogs are very intimidating with a short stiff coat, huge head and rippling muscles. In Roman times these dogs were used as war dogs who fearlessly charged enemy lines with flaming oil-filled buckets attached to their backs.
  • Neopolitan Mastiff: The massive Neopolitan mastiff has been guarding homes against intruders since the days of ancient Rome. This heavily wrinkled behemoth is sweet to its loved ones but wary of strangers. Its massive head is so wrinkled it looks as if it melted in the sun! Neopolitans come in black, mahogany, tawny and blue.
  • French Mastiff: Also known as Bordeaux mastiff, the Bordeaux has a powerful, muscular body capable of pulling carts, transporting heavy objects and guarding flocks. They are fawn-colored with a massive bulldog-like head and undershot jaw.
  • Tibetan Mastiff: These imposing giants are considered one of the best guard dogs with their watchful, imposing and intimidating presence. Sweet and mellow with their families, Tibetan mastiffs are territorial and somewhat aloof with strangers. These noble canines have v-shaped ears and expressive brown eyes.

Mastiffs are vulnerable to several eye issues. One of them is called progressive retinal atrophy. This condition occurs when the photoreceptor cells in the dog’s eyes start to deteriorate. It can lead to partial or full vision loss.

Mastiffs are known to be good family dogs with affectionate, friendly personalities.

Temperament and Behavior

These dogs have an affectionate, friendly personalities. This is what makes them good family dogs. They fit in best with families who have older children. At times, this dog’s behavior can be described as that of a couch potato. They’d like nothing more than to sit on the couch next to their owner. However, these dogs need regular exercise such as a walk in the woods, a game of chase in the backyard, or fetching a ball to stay in good health.

One of the most notable traits of this breed is its sensitive nature. They have a talent for reading the facial expressions of their owners. They are people pleasers! This makes obedience training a relatively easy process. But, keep in mind, when an owner speaks with a harsh tone, this dog’s feelings will be hurt. It’s best for an owner to use treats and words of praise with a mastiff during obedience training.

How to Take Care of a Mastiff

As with any breed of dog, this dog needs a certain type of care to maintain good health. For instance, feeding this pet a balanced diet throughout its life can help to prevent the common health issues mentioned above. Furthermore, puppy and adult mastiffs both need the proper amount of exercise each day to stay in shape.

The Best Dog Food for Mastiffs

Not surprisingly, a puppy requires a different diet than an adult dog. Look at the specific ingredients in the feeding routines of puppies and adult dogs. Because of this dog’s immense size, it’s even more crucial to provide adequate nutrition throughout each life stage that’s tailored to the dog’s size and health profile.

Puppy food: The goal of quality puppy food is to promote a slow rate of growth. It’s important for a puppy’s joints, bones, muscles, and tendons to gain strength gradually. This can prevent health problems like hip and elbow dysplasia brought on by a puppy gaining too much weight too quickly. Protein is the main ingredient in quality mastiff puppy food. It builds muscle and contributes to the health of a puppy’s skin and coat. It also provides energy to a puppy without adding needless weight. Calcium is important for the proper growth of bones and teeth. DHA is another ingredient important for brain development and continued eye health. DHA is an ingredient that can work to prevent progressive retinal atrophy.

Mastiffs need plenty of protein and Omega fatty acids in their diets. They won’t be happy if presented with cabbage.

Adult dog food: Protein is an important ingredient in an adult’s food as well. This nutrient gives the dog energy and continues to build strong bones and muscles in an effort to prevent hip and elbow dysplasia. Omega-3 and Omega-6 fatty acids contribute to an adult dog’s healthy coat and skin. Antioxidants in the food support the dog’s immune system.

Maintenance and Grooming

How much does a mastiff shed? The English, Neapolitan, and Bullmastiff are all moderate shedders. The Tibetan mastiff sheds very little while its cousin the French mastiff is a heavy shedder. These dogs shed more during the change of seasons. Mastiffs have a double coat of short hair. The daily grooming routine of this breed of dog is relatively easy. A soft brush with boar’s hair bristles is excellent for removing loose or dead hair from this dog’s coat.

A grooming glove is another effective tool especially when it comes to removing loose hair from the dog’s legs and wrinkly face. A grooming glove offers more control while working around the dog’s ears, nose, and eyes. It’s best to brush the dog starting at the head and ending at its tail. This helps an owner brush the hair in its natural direction.

An owner should be on the lookout for skin conditions including patches of dry skin, bald spots, and itchy areas. These can be caused by food or skin allergies or even using a shampoo with ingredients that irritate the dog’s skin.

Mastiff Training

All mastiffs including the Bull, English, French, Italian, Neapolitan, and Tibetan share a sensitive nature. They are relatively easy to train but need an owner to be firm without using harsh words. An owner who uses a harsh tone is not likely to have success in training a mastiff. Words of praise and treats go a long way to effectively conveying obedience lessons to a mastiff. A Great Dane is another large dog with a sensitive nature. It’s relatively easy to train as well when an owner uses words of praise and rewards.

Exercise

Though these dogs are not high-energy dogs, they need daily exercise to control their weight and avoid developing bone, joint, and muscle health issues. Twenty to thirty minutes of exercise per day is a good amount for a mastiff. An ideal exercise routine is a slow walk through the woods or the neighborhood. An owner should avoid jogging with a mastiff because these dogs can become overheated in a short time.

Though these dogs aren’t overly active, it’s not a good choice for apartment life. Its large size would not be suitable for a small living space. This breed needs a backyard where it can stretch its legs and get some fresh air for part of the day.

Puppies

A mastiff puppy should never be overfed. When a mastiff puppy grows and gains weight too quickly, it puts them at risk for developing health issues. Their bones, muscles, and joints need time to develop so they can fully support their large adult body.

These puppies need daily exercise just as adult dogs do. Twenty minutes of walking per day can help a puppy to burn fat.

Children and Mastiffs go Well Together

These dogs are good family dogs and do well with children in a home. These are affectionate, gentle dogs. However, it’s a good idea for a family with small children to get a mastiff puppy. That way, the mastiff has an opportunity to learn how to interact with small children and become accustomed to their behavior.

Dogs Similar to a Mastiff

Some breeds similar to the mastiff include the Great Dane, the Boxer, and the Irish Wolfhound.

  • Great Dane – Great Danes and mastiffs are both large dogs. They are both sensitive and friendly. However, Great Danes are a little more energetic than mastiffs.
  • Boxer – Boxers and mastiffs do well with children and have a simple grooming routine due to their short-haired coats. Boxers tend to be a little more playful than mastiffs.
  • Irish Wolfhound – Irish Wolfhounds are affectionate with a sweet nature like mastiffs. Both these dogs don’t like to be left alone and suffer separation anxiety. An Irish Wolfhound is not as good a guard dog as a mastiff.

About the Author

After a career of working to provide opportunities for local communities to experience and create art, I am enjoying having time to write about two of my favorite things - nature and animals. Half of my life is spent outdoors, usually with my husband and sweet little fourteen year old dog. We love to take walks by the lake and take photos of the animals we meet including: otters, ospreys, Canadian geese, ducks and nesting bald eagles. I also enjoy reading, discovering books to add to my library, collecting and playing vinyl, and listening to my son's music.
