Bullmastiff vs Pit Bull is a common dilemma for people looking for an affectionate dog with strong protective instincts. While both these breeds certainly tick those boxes, there are some key differences between them that are worth considering.

If you lead a highly active lifestyle and are looking for a dog who will want to join in on all the fun, then the energetic and clown-like personality of the Pit Bull is going to be a better choice for you than the naturally quieter and more sloth-like Bullmastiff.

And yet if what you’re after is a courageous protector who will devotedly watch over you and your family and guard you with its life, the Bullmastiff is going to do a far superior job than the overly friendly and excitable Pitbull.

Regardless of what temperament and traits you most value, both breeds make fantastic family dogs, it’s simply a matter of which one will be a more suitable fit for your home and lifestyle.

Before we dive in to exploring these two canines, its worth noting that while there are several breeds of Pitbull, in this article when we use the term Pitbull were referring to the American Pitbull Terrier. Now that weve cleared up any potential confusion, heres everything you need to know about the Bullmastiff and the Pit Bull to help you find the right forever friend for your family.

The Ultimate Canine Face-Off: Bullmastiff vs. Pitbull

Ever wondered who would win in a showdown between these two powerful breeds? You’re not alone This question has sparked heated debates among dog enthusiasts everywhere. Today, I’m gonna dive deep into this controversial topic, comparing these impressive canines across various aspects to determine if a Bullmastiff could actually defeat a Pitbull in a confrontation.

First things first – I want to make it absolutely clear that dog fighting is illegal and unethical. This article is purely educational examining breed characteristics without encouraging any form of animal confrontation.

Understanding the Contenders: Breed Backgrounds

The Bullmastiff: The Gentle Giant

Bullmastiffs originated in 19th century England where they were bred specifically to guard estates from poachers. These impressive dogs can weigh up to 130 pounds and are known for their:

  • Muscular, powerful build
  • Calm and gentle temperament (despite their size)
  • Natural protective instincts
  • Loyalty and affection toward family members
  • Minimal grooming needs and moderate exercise requirements

Despite their imposing appearance Bullmastiffs are generally gentle giants who prefer lounging around with their families rather than picking fights.

The Pitbull: The Athletic Powerhouse

The term “Pitbull” actually encompasses several breeds, most commonly the American Pit Bull Terrier. These dogs were initially bred for blood sports in 19th century England, created by crossing Bulldogs and Terriers. Key characteristics include:

  • Strong muscular build
  • Remarkable agility and athleticism
  • Powerful jaw strength
  • High energy levels
  • Loyalty and affection toward owners

Despite their unfair reputation, well-raised Pitbulls are typically loving and playful dogs who form strong bonds with their families.

The Physical Matchup: Strength, Size, and Power

When comparing these two breeds physically, several key factors come into play:

Size Comparison

Characteristic Bullmastiff Pitbull
Height 24-27 inches 17-21 inches
Weight 100-130 pounds 30-70 pounds
Build Massive, heavy-boned Compact, muscular

The Bullmastiff clearly has a significant size advantage, outweighing the Pitbull by a considerable margin in most cases.

Strength and Agility

While the Bullmastiff has impressive raw strength due to its size, Pitbulls are known for their exceptional power-to-weight ratio. Pitbulls possess superior agility, speed, and stamina. They’re more athletic and have higher energy levels, which could give them an edge in a prolonged encounter.

Bite Force

Bite force is often mentioned in these discussions. Contrary to popular belief, Pitbulls don’t have the strongest bite among dog breeds. Their bite force measures around 235-330 PSI (pounds per square inch), while a Bullmastiff’s bite force is typically around 230 PSI. Not a significant difference, but worth noting.

Combat Capabilities: The Deciding Factors

When examining which breed might prevail in a confrontation, several factors beyond mere size must be considered:

Temperament and Fighting Style

Bullmastiffs were bred to track down and pin poachers, not to fight other dogs. They typically use their size and weight to intimidate and restrain rather than engage in prolonged combat. Their fighting style is more defensive than offensive.

Pitbulls, with their history in blood sports, were specifically bred for dog fighting. They possess natural fighting instincts, tenacity, and a higher pain tolerance, allowing them to continue fighting despite injuries.

Stamina and Endurance

This is where the Pitbull has a clear advantage. Bullmastiffs, while powerful, tire more quickly due to their large size. Pitbulls have remarkable stamina and can maintain high energy levels for extended periods. In a prolonged confrontation, this endurance could be decisive.

Trainability and Intelligence

Both breeds are intelligent, but there are differences in their trainability:

  • Bullmastiffs are intelligent but can be somewhat stubborn. They’re quick learners but may show independence in decision-making.
  • Pitbulls are highly trainable and eager to please their owners. They excel in various training activities and have a strong work ethic.

Expert Verdict: Who Would Win?

According to multiple veterinary and canine experts, despite the Bullmastiff’s impressive size advantage, a Pitbull would likely win in a hypothetical confrontation. Here’s why:

  1. Superior agility and speed: Pitbulls can outmaneuver the larger, slower Bullmastiff
  2. Greater endurance: Pitbulls can maintain high energy levels longer than Bullmastiffs
  3. Fighting instinct: Pitbulls were specifically bred for combat, unlike Bullmastiffs
  4. Tenacity: Pitbulls have an unwavering determination in confrontations
  5. Pain tolerance: Pitbulls can continue fighting despite injuries

As one veterinary source clearly stated: “No, a Bullmastiff cannot beat a Pitbull in a fight due to the Pitbull’s superior strength and agility.”

Other Breeds That Could Challenge a Pitbull

While we’re on the topic, it’s worth noting that several other dog breeds potentially have the physical capabilities to match or defeat a Pitbull:

  • Kangal (highest bite force among domestic dogs)
  • Caucasian Shepherd
  • Cane Corso
  • Tosa Inu
  • Dogo Argentino
  • Wolfdog
  • Akita
  • Neapolitan Mastiff
  • Belgian Malinois
  • Rhodesian Ridgeback
  • Anatolian Shepherd

Responsible Ownership: What Really Matters

I wanna emphasize that this whole “who would win” debate misses the most important point about dog ownership. What truly matters is:

  • Proper training and socialization from an early age
  • Responsible ownership including proper exercise and mental stimulation
  • Understanding breed characteristics to provide appropriate care
  • Loving environment where dogs can thrive as family companions

Both Bullmastiffs and Pitbulls can make wonderful family pets when raised with love, consistent training, and proper socialization. Their behavior ultimately depends more on their upbringing than their breed.

Common Misconceptions About Both Breeds

Let’s clear up some common misconceptions:

Bullmastiff Myths:

  • Myth: Bullmastiffs are aggressive dogs
  • Reality: They’re typically gentle and calm, though protective when needed

Pitbull Myths:

  • Myth: Pitbulls have locking jaws
  • Reality: There’s no anatomical mechanism that allows their jaws to “lock”
  • Myth: All Pitbulls are naturally aggressive
  • Reality: Well-raised Pitbulls are loving and affectionate pets

Health Considerations for Both Breeds

If you’re considering either breed as a pet, be aware of these common health issues:

Bullmastiff Health Concerns:

  • Hip dysplasia
  • Bloat
  • Obesity
  • Joint problems

Pitbull Health Concerns:

  • Allergies
  • Skin conditions
  • Heart diseases

Both breeds require regular veterinary check-ups and a balanced diet to maintain optimal health.

My Personal Take

After researching this topic extensively, I gotta say that while the evidence suggests a Pitbull would likely win in a hypothetical confrontation with a Bullmastiff, I think the entire conversation misses what’s truly important about dog ownership.

These magnificent animals weren’t put on earth to fight each other. They’re here to be our companions, protectors, and friends. The true measure of a dog’s worth isn’t its fighting ability but the love and loyalty it brings to our lives.

If you’re considering either breed, focus on finding a reputable breeder or rescue organization, understand the specific needs of the breed, and commit to providing a loving home with proper training and care.

So, can a Bullmastiff beat a Pitbull? Probably not, according to experts. But the better question is: does it matter? Both breeds have their unique strengths and qualities that make them special.

Bullmastiff vs Pit Bull: Intelligence and trainability

Both the Bullmastiff and the Pit Bull are known for being highly intelligent, which would make them a breeze to train if it weren’t for the fact that both breeds can also be stubborn at times.

The Bullmastiff is more of an independent thinker than the Pit Bull, so of the two breeds, they’re more likely to need firm consistency to keep them on track. Pit Bulls tend to be very eager to learn, so as long as you keep things upbeat, they’ll tend to cotton on quickly.

Both breeds need a lot of positive reinforcement and admonishing them for bad behavior is best avoided as this can lead to them becoming unresponsive. Using the best dog treats as part of your praise and reward system will work wonders with both the Bullmastiff and the Pit Bull.

With both these dogs, you’ll want to make socialization and obedience training a top priority, beginning as soon as your puppy is old enough to start attending classes and mastering commands.

This is very important as Bullmastiffs have a tendency to want to jump up on people, which given their size, poses a very real safety risk to others. Pit Bulls, on the other hand, were trained as fighting dogs, which means they’re not always tolerant of other animals, so socializing them early on can help prevent any issues.

Bullmastiff vs Pit Bull: Size and appearance

Male Bullmastiffs typically reach a height of between 25-27 inches, with females coming in slightly shorter at between 24-26 inches. In terms of weight, it’s not unusual for males to tip the scales at anywhere between 110-130lbs, with females sitting somewhere between 100-120lbs.

Appearance wise, the Bullmastiff is large-boned and muscular, with a short coat that comes in three colors: fawn, red or brindle. Their dark eyes, v-shaped ears and deep muzzle come together to create an imposing figure that gives the Bullmastiff an alert and confident appearance.

In contrast, the Pit Bull is much more compact with males measuring around 19 inches and females coming in at roughly 18 inches. Given their relatively short stature, the Pit Bull is heavy for its size, with males and females clocking in at between 50-80lbs.

Strong and stocky, the Pit Bull packs more muscles per pound of body weight than any other breed and they have a short and sleek coat which comes in a variety of colors. They tend to have small eyes and their ears may be cropped or uncropped.
