They’re a fascinating mix of contrasting traits, as they’re powerful yet gentle, imposing yet friendly, and massive yet extremely affectionate.

These traits all blend into a unique, lovable personality that has endeared the Mastiff to dog lovers for centuries.

History of the English Mastiff

The English Mastiff’s roots go deeper than an old oak tree’s. They’re an ancient breed, with ties dating back to Roman times. Roman soldiers were said to be awestruck by the size and strength of these dogs, which they saw when invading Britain in 55 BC. It wasn’t long before they were using Mastiffs in their armies and arenas, cementing the breed’s place in history.

Later, in the Middle Ages, Mastiffs were used for both protection and hunting due to their strength and courage. They were even said to have been used in wars, standing alongside knights in battle.

Isn’t it incredible how such a noble and peaceful breed has roots so entwined with battles and warriors?

3 Little-Known Facts of an English Mastiff

But history is just the tip of the iceberg. Let’s delve into some lesser-known facts about these majestic beasts:

  1. Size Matters: The English Mastiff holds the record for the heaviest dog ever recorded. A Mastiff named Zorba weighed a staggering 343 pounds!
  2. The Quiet Type: Despite their size, Mastiffs are known to be quite quiet. They don’t bark unnecessarily, and when they do, it’s usually for a good reason.
  3. Long-Lived Legends: Many large dog breeds have relatively short lifespans. The English Mastiff, however, bucks this trend, often living to the ripe old age of 10 to 12 years.

Appearance and Size of an English Mastiff

Now, let’s turn to the physical attributes of this colossal breed. English Mastiffs are often described as “head turners”, and for a good reason. With a broad, square head adorned by a short muzzle and droopy eyes, they exude a certain nobility. Their bodies are a powerful testament to their strength, with a muscular frame draped in a coat that comes in fawn, apricot, or brindle.

In terms of size, these dogs are undeniably colossal. Males typically stand 30 inches tall at the shoulder and weigh anywhere between 160 to 230 pounds. Females are slightly smaller but are still large compared to most other breeds.

Temperament & Intelligence

While the English Mastiff might be a giant, they are truly a “gentle giant”. This breed is known for its serene demeanor and docile nature. But don’t mistake their calmness for stupidity. These dogs are sharp as a tack and possess a keen instinct that makes them excellent guard dogs.

Have you ever noticed how a Mastiff can go from a lazy loaf on your living room floor to an alert sentinel in a blink when they sense something amiss?

Are These Dogs Good for Families?

Absolutely, English Mastiffs are as much family dogs as they are guardians. They are known for their patience and tenderness with children, often acting as gentle babysitters. In fact, their protectiveness extends to all family members.

They are deeply loyal dogs who would do anything to ensure the safety and happiness of their loved ones.

Does This Breed Get Along With Other Pets?

If you’ve got a household full of pets and you’re wondering if a Mastiff will play nicely with them, the answer is a resounding yes! English Mastiffs are generally very accepting of other dogs and pets. Their gentle nature and patience often make them good companions for other animals.

Important Things to Know

There are some important things to know and understand when owning or looking for an English Mastiff. So, let’s dive right in.

Food & Diet Requirements

Given their size, it’s no surprise that English Mastiffs have a hearty appetite. A balanced diet for a Mastiff includes high-quality commercial dog food, rich in proteins and balanced with fruits, vegetables, and whole grains. Remember, overeating can lead to obesity, a common issue in the breed, so portion control is vital.

Who would’ve thought that these giants would require such a measured and careful approach to diet?


Despite their size, English Mastiffs are not overly active dogs. They require moderate daily exercise to keep them healthy and happy. This could include a couple of short walks and some playtime in the yard. But remember, excessive exercise, especially for puppies, can damage their growing bones and joints.

So moderation is key.


Training a Mastiff requires patience, consistency, and a lot of positive reinforcement. They respond well to rewards and praise, but harsh training methods can often backfire. Like any other breed, early socialization and puppy training classes are beneficial for a well-rounded and well-behaved Mastiff.


Grooming an English Mastiff is not as demanding as one might think. Despite their size, these dogs have a relatively easy-to-maintain coat. Regular brushing will keep their coat healthy and shiny, while baths are typically needed only every few months or so.

However, cleaning their face and wrinkles is an everyday task to prevent any skin issues.

Health and Conditions

One of the realities of owning an English Mastiff, or any dog breed for that matter, is the potential for health issues. These giant dogs, despite their strength and resilience, are prone to a few specific health conditions that potential owners should be aware of.

So, let’s lift the curtain and take a closer look at the potential health issues that these giants might face.

1. Hip and Elbow Dysplasia: This is a common skeletal condition often seen in large dog breeds like the English Mastiff. Dysplasia is a developmental abnormality where the hip or elbow joint doesn’t fit correctly into the socket, leading to pain, inflammation, and difficulty moving. Over time, this could result in arthritis. Genetic factors, rapid growth, and excessive exercise can contribute to its development.

2. Obesity: Due to their large size and love for food, English Mastiffs can quickly put on extra weight if their diet isn’t properly managed. Obesity can exacerbate skeletal issues and lead to other health problems such as heart disease and diabetes.

3. Heart Conditions: Several heart conditions can affect English Mastiffs, including dilated cardiomyopathy (a disease of the heart muscle that leads to decreased heart function), aortic stenosis (a narrowing of the heart’s aortic valve), and mitral valve disease.

4. Cancer: Unfortunately, Mastiffs are more prone to certain types of cancer than other breeds. These include lymphoma, bone cancer, and mast cell tumors.

5. Gastric Torsion (Bloat): This life-threatening condition occurs when a dog’s stomach fills with gas and possibly twists, cutting off blood flow. Large, deep-chested dogs like Mastiffs are especially at risk. Immediate veterinary attention is crucial if bloat is suspected.

6. Progressive Retinal Atrophy (PRA): This is a family of eye diseases that involves the gradual deterioration of the retina. Early in the disease, affected dogs become night-blind, with a loss of daytime vision occurring as the disease progresses.

To mitigate these potential health risks, regular vet visits, a balanced diet, adequate exercise, and genetic screening (for conditions like hip dysplasia and PRA) are paramount. Remember, an ounce of prevention is worth a pound of cure.

As always, when adopting an English Mastiff puppy, ensure it comes from a reputable breeder who tests their breeding dogs for various health conditions.

A responsible breeder will be upfront about the potential health risks and should provide documentation of health clearances.

Male vs Female

Finally, the eternal question – male or female? In terms of size, males are generally larger than females. But when it comes to temperament, the differences are less clear. Both genders are known to be affectionate, loyal, and protective.

However, males may be more territorial, while females might be more independent. The choice between a male or a female ultimately depends on your personal preference.

Key Takeaways
