Are Mastiffs Aggressive? Temperament & Personality Traits

Mastiffs are some of the largest dog breeds in the world, featuring a kind, noble, and loyal disposition. Unfortunately, this dog breed is shrouded in myths and misconceptions. They often receive a bad reputation as an overly aggressive dog breed due to their physical traits, low intelligence, and temperament.

However, Mastiffs are not overly aggressive. They are family protectors and gentle companions, making them suitable family pets. Granted, they may be polite, but some can be extremely shy, while some may display some aggression. To ensure that they have a stable temperament, they need frequent socialization from an early age.

In this article, we will discuss everything you need to know about Mastiffs to find out if it’s a dangerous dog breed and whether you should keep it as a pet.

Why Are Mastiff Dogs Considered Dangerous and Aggressive

English Mastiffs were initially bred for guarding purposes. They feature certain physical traits meant to accomplish their guarding role, but unfortunately, they are also the reason behind the negative reputation of Mastiffs.

Among the physical attributes that portray them as dangerous and aggressive include their gigantic body and some body parts that stand out.

Their weight and size vary depending on a specific gender. While the male Mastiff grows up to 30 inches and weighs between 160–230 pounds, the females can grow up to 27.5 inches weighing about 120–170 pounds.

Furthermore, Mastiffs tend to have an appealing posture and a very powerful chest. They also feature a large head, long and thin ears positioned too low on the head, and curved tails set moderately high on their backs. These features appear intimidating and can chase away any potential intruders into your property.

So, Are They Aggressive?

While many people may believe that Mastiffs are an aggressive breed, the most ideal description for this behavior is being protective.  They may display aggression when protecting their owners or themselves. The only reason why Mastiffs may be overly aggressive is because of a lack of socialization and poor training practices.

If a mastiff is raised in a home with abuse, neglect, maltreatment, or punishment, they are likely to develop fear-related aggression, and this behavior can be hard for the dog to unlearn.

Also, as watchdogs, Mastiffs can be too hostile and territorial towards other dogs, even with familiarization. This overprotective nature is usually developed in puppyhood. Nevertheless, modern-day Mastiff dogs are gentle and friendly, only showing aggression if the owner is threatened.

Therefore, if you are looking for a loyal and courageous dog to guard your property, the Mastiff may be the right choice for you.

Nevertheless, keep in mind that other dogs may not be able to live with Mastiffs due to their energy levels and huge size. Furthermore, if you have smaller pets and children in your home, Mastiffs may not be the right breed for you.
