Mastiffs have a reputation for being aggressive, but is this really true? According to a study, Mastiffs are actually one of the least aggressive breeds of dogs.

In fact, the American Kennel Club describes Mastiffs as "gentle giants." This is likely due to their calm and gentle nature, which is a result of their breeding history as guard dogs.

Despite their large size, Mastiffs are often described as "laid-back" and "easy-going." This makes them a great choice for families with children, as long as they receive proper training and socialization.

Aggressive Breeds

Excessive barking is a common trait associated with aggressive dog breeds.

Statistically, many of these dogs have an increased risk of harming another pet or a person, which is often why management companies will set restrictions.

Assigning an aggressive label to a particular breed is all about safety.

Some common behaviors of aggressive dog breeds include lunging or charging at people and other pets, snapping and snarling, barring teeth, and biting.

If you have a "banned" breed, you may wonder whether it's legal to restrict certain breeds.

Management companies set restrictions due to the increased risk of harm posed by these breeds.

Here are some common characteristics of aggressive dog breeds:

  • Excessive barking
  • Lunging or charging at people and other pets
  • Snapping and snarling
  • Barring teeth
  • Biting

Understanding Aggression

Aggression in dogs is a normal behavior that can be adaptive or appropriate in certain contexts, such as when a dog defends its owner from an intruder. However, it can also be socially unacceptable when it involves harming others.

Assigning an aggressive label to a particular breed is about safety, as some breeds have an increased risk of harming others. But, it's not just about breed - many factors can contribute to aggression, including fear, resource guarding, territorialism, and pain.

Aggression may vary depending on a dog's age, breed, size, and home dynamic. For example, older dogs, male dogs, small dogs, and dogs that lack the company of other dogs are more likely to be aggressive. A recent study found that certain breeds, such as Collies (rough), Toy Poodles, and Miniature Schnauzers, have a higher odds of aggressive behavior than others, like Labrador Retrievers and Golden Retrievers.

What Is Aggression?

Aggression in dogs is a normal behavior that's part of their natural repertoire. It's not something to be feared or stigmatized, but rather understood.

Aggression can manifest in different ways, such as threatening or harmful behavior. This behavior is often intended to avoid conflict escalation, increase distance between the dog and the target, or cause damage to the target.

Aggression can be adaptive or appropriate in certain contexts, like when a dog attacks an intruder. In this case, we'd likely praise the dog's courage and loyalty.

Aggression is a complex behavior influenced by genetic and environmental factors. It's not solely caused by one thing, but rather a mix of things that shape a dog's behavior.

All dogs can be aggressive, and it's not something to be ashamed of. It's a natural part of being a dog.

What Causes Aggression?

Aggression in dogs can be caused by a variety of factors, including fear, which is the most common cause. Fear-based reactivity can lead to a dog trying to put distance between themselves and the target, but it can also escalate into defensive aggression over time.

Maternal aggression is another cause, where a mother dog is overly protective of her puppies. Resource guarding is also a common cause, where a dog defends items of perceived value like bones or toys. Territorial aggression is when a dog protects what they see as their domain, such as the backyard or the car.

Protective aggression is when a dog guards a human, like their owner. Pain aggression is when a dog experiences discomfort and defends against any touch or movement that might intensify that pain.

Research has shown that certain factors can increase the probability of aggression in dogs. These include age, with older dogs being more likely to be aggressive. Male dogs, small dogs, and dogs that lack the company of other dogs are also more likely to be aggressive.

Dogs with novice owners and fearful personalities are also more likely to be aggressive. Certain breeds, such as Collies (rough), Toy Poodles, and Miniature Schnauzers, have been found to have a higher odds of aggressive behavior than other breeds.

Here are some common signs of aggression in dogs:

  • Excessive barking
  • Lunging or charging at people and other pets
  • Snapping and snarling
  • Barring teeth
  • Biting

It's essential to note that aggression is a normal dog behavior, which can be adaptive or appropriate in certain contexts. For example, if a dog attacks an intruder, it's considered courageous and loyal behavior. However, aggression can also be a sign of underlying issues that need to be addressed.

Breed Characteristics

Mastiffs are known for their large size and strength, which can contribute to issues if not properly managed. This is especially true if behavioral problems aren't addressed or if the dog isn't socialized from an early age.

Some mastiff breeds, like the Neapolitan mastiff, are fiercely loyal and protective, but can be aggressive toward strangers or perceived threats, requiring firm training and command to control.

Genetics can also play a role in aggression, particularly in breeds that were selectively bred for activities like guarding or fighting. The Neapolitan mastiff's history as a guard dog is a prime example of this.

Here are some key breed characteristics that can influence aggression:

  • Genetics: Breeds bred for guarding, hunting, or fighting may be more prone to aggression.
  • Strength and size: Larger, stronger dogs may be more likely to exhibit aggressive behavior.
  • Trainability: Dogs that are stubborn or difficult to control may be more challenging to manage.

It's essential to remember that individual variation plays a significant role in aggression, and proper socialization, training, and behavior modification techniques can help raise a dog's threshold for aggressive behavior.

Breed Characteristics

Bullmastiffs can weigh between 100 and 130 pounds, making them a seriously large breed.

Their guarding instinct is strong, but they're actually easy to train and socialize with regular walks and early socialization.

Bullmastiffs are quite lazy and lethargic, which makes them suitable for smaller spaces and fewer walks.

Many apartments have breed restrictions that include Bullmastiffs due to their size and guarding instincts.

Chow Chows have a reputation for being aloof and aggressive due to their original breeding as guard dogs and hunting dogs.

Consistent training and firm command are essential to curb aggressive behaviors in Chow Chows.

Chow Chows can form strong bonds with their families, but their protective and territorial natures may lead to aggression towards strangers or other animals.

Fila Brasileiro

The Fila Brasileiro is a breed that's not for the faint of heart. They're naturally aggressive and unforgiving hunters, making them a challenge for inexperienced owners.

In a residential setting, their impetuous and dominant temperament can be a recipe for disaster. They should always be well-controlled and monitored, especially around people and animals they don't know.

Apartment complexes often have breed restrictions against the Fila Brasileiro due to these concerns. If you're considering bringing one home, be sure to check your apartment's pet policies and be prepared for the specific care needs of this breed.

Here are some key characteristics to keep in mind:

  • Aggressive and unforgiving hunter
  • Impetuous and dominant temperament
  • Requires experienced owners
  • May have breed restrictions in apartment complexes

Canarian Mastiff

The Canarian Mastiff, also known as the Perro de Presa Canario or Canary Mastiff, is a giant mastiff breed. They were bred in the Canary Islands as a herding dog for cattle and pigs, and as a herd protector to drive away threatening animals.

To own a Canarian Mastiff, you'll need to be a firm, experienced dog owner who can provide constant training and socialization. They require a six-foot fence to prevent them from preying upon neighborhood animals.

Their territorial nature makes them distrustful toward strangers, and they're genetically prone to aggression, even among the humans or dogs they live with. This breed is not for the faint of heart.

They're best suited for owners who know how to properly socialize dogs and curb aggressive behaviors, and who can provide the necessary care and attention.

The Gull Dong is a medium-sized dog with short, smooth fur.

This breed is considered strong-willed, making it difficult to train.

They are very aggressive and have a history of being used for fighting.

Unfortunately, the Gull Dong is still used for fighting in Pakistan and India today.

They are common in Pakistan, but fairly rare in the United States.

Individual Variation

Individual Variation is a crucial aspect to consider when thinking about breed characteristics.

Dogs differ in their likelihood to show aggressive behavior in any particular situation. Some dogs tend to respond aggressively with very little stimulation.

The difference in this threshold at which a dog displays aggressive behavior is influenced by both environmental and genetic factors. This means that a dog's behavior is shaped by its upbringing and genetics.

If a dog's threshold is low, it will be more likely to bite. Raising the threshold, on the other hand, makes a dog less likely to respond aggressively.

This threshold can be raised using behavior modification techniques. Working with aggressive dogs can be potentially dangerous, so it's essential to do it under the guidance of an experienced animal behavior professional.

The ease with which a dog's threshold can be changed is influenced by its gender, age, breed, general temperament, and the chosen behavior modification techniques.

What Makes a Breed?

So, what makes a breed? Well, genetics play a big role, especially in breeds that were purposefully bred for activities like guarding, hunting, and fighting. This can lead to a higher risk of aggression.

Some breeds have a high prey drive, which can make them more prone to chasing small animals. This is often seen in breeds that were bred for hunting.

Strength and size of the dog can also be a factor, including jaw strength and bite power. This is especially true for breeds that were bred for guarding or fighting.

Trainability is another important aspect, with some breeds being more stubborn or difficult to control. This can make training more challenging and increase the risk of aggression.

Behavioral issues like boredom, anxiety, fearfulness, or stress can also contribute to aggression in dogs. This is why proper socialization and training are crucial.

Here are some key factors that can influence a breed's temperament:

  • Genetics
  • High prey drive
  • Strength and size
  • Trainability
  • Behavioral issues
  • Territorial behavior

The American Temperament Test Society, Inc (ATTS) also plays a role in determining canine temperament. Their testing helps breeders identify specific temperament characteristics and provides owners with valuable insights into their pet's temperament.

Handling Aggression

Reactive dogs can become aggressive depending on the situation and past experience, as reactivity puts a dog at high risk of acting aggressively due to a heightened emotional state.

If a reactive dog's growl is ignored, they may learn to escalate to snapping and biting to achieve their goal of increasing distance between themselves and a perceived threat.

A reactive dog's behavior can morph into defensive aggression over time, especially if their attempts to create distance between themselves and a stimulus have repeatedly failed.

It's essential to note that a dog's behavior can escalate during a single interaction with another individual, making it crucial to intervene early and effectively.

Decision Making

When adopting any dog, it's crucial to provide early socialization and consistent training by a firm owner.

Most individual dogs of so-called aggressive breeds, like mastiffs, can make good pets with proper training.

However, some dogs' aggressive tendencies may never be fully overcome, and they may not integrate well into certain households.

Do your research and consider asking local veterinarians and pet trainers for their input before adopting a mastiff.

You'll also want to protect any dog you get with pet insurance in case of any accidents or injuries that affect their health.

Ultimately, it's essential to consider whether you are able to provide the necessary discipline and attention for a mastiff.
