Beware of the Most Aggressive Dog Breeds - Never Catch Them in a Bad Mood!

Dogs are famously known as man's best friend. They are loyal and undoubtedly one of the most adorable creatures on the planet. However, not all dogs share this gentle and friendly nature. In fact, some can be extremely aggressive. And we're not just talking about those big, muscular dogs that may seem intimidating at first glance.

Even small dogs can surprisingly exhibit hostile behavior and display aggressive traits. Here is a list of the most frightening dog breeds that can become dangerous and difficult to manage without proper training and care.

Hybrid Wolf

The hybrid wolf is a mix between a wolf (particularly the gray wolf) and a dog. This breed can vary in size, depending on the particular wolf species and type of dog involved in the equation. Generally, they can reach a height of 83 cm and weigh up to 57 kg. The danger with this breed lies in their unpredictable behavior. They can appear friendly one moment and turn unfriendly the next.

These dogs possess the predatory instincts of wolves, making them potentially very dangerous if not properly trained. When provoked, they can be even more hostile than wild wolves. For this reason, owning them is illegal in most countries.

Caucasian Ovcharka

The Caucasian Ovcharka, also known as the Caucasian Shepherd, is a large breed that was bred to guard livestock and homes from wild predators wandering in the mountainous regions of the Caucasus. These dogs may look warm and domesticated, but they are also agile and powerful enough to chase down prey such as bears. The size and ferocity of the Caucasian Ovcharka make it an intimidating breed.

Many of them can easily dominate their owners once they stand on their hind legs. This breed is known to be authoritative, stubborn, and aggressive. Without proper training, the Caucasian Ovcharka can become a fierce beast.

Pitbull

The pitbull is a breed that descends from bulldogs and terriers. These dogs were originally bred to bait bulls and bears for hunters. They are muscular and very strong, making them favorites for dog fighting. Pitbulls are often unfairly judged as inherently violent. In fact, they are even banned in some communities.

Experts explain that a pitbull's temperament depends on how it is treated and trained. When given love and care, these dogs can also be affectionate and gentle.

Tosa Inu

The Tosa Inu is a rare dog breed from Japan. They were once bred in Tosa, Shikoku, Japan – hence the name. They were bred for one sole purpose: fighting. In fact, it is the only breed used in Japanese dog fights. This pooch is highly intimidating due to its size, reaching up to 91 kg and growing up to 81 cm tall.

Once provoked, the Tosa Inu can dominate another dog and is even powerful enough to dominate a human being. Owning this breed is restricted in some countries as it is considered dangerous.

Rhodesian Ridgeback

The Rhodesian Ridgeback is a large breed originating from South Africa. They were bred to keep lions away from villages and livestock. If this dog is aggressive enough to fight lions, you definitely don't want to provoke it! The Rhodesian Ridgeback is well-known for being challenging to tame.

They are often hostile towards strangers, requiring lots of positive reinforcement to gain their trust and loyalty. But once those barriers are broken, these dogs become fiercely protective and loyal companions.

Argentine Dogo

Originating from Argentina, the Argentine Dogo is a muscular and imposing breed renowned for its prowess in hunting large game, including wild boars and even pumas. With its bravery and protective nature towards its masters, it's no wonder this breed is celebrated.

Provoking a Doberman Pinscher can unlock their full potential for danger, as their bite force is estimated to be a staggering 600 PSI (pounds per square inch). This breed has a reputation for aggression towards strangers and other dogs.

German Shepherd

One of the most popular breeds globally, German Shepherds embody intelligence, courage, and unwavering devotion, making them outstanding utility dogs for police work, search and rescue missions, and breeding programs.

The Alaskan Malamute, bred for sledding and hunting, is a large and robust breed known for its strength and stamina in carrying heavy cargo. Resembling Siberian Huskies but larger and fluffier, Alaskan Malamutes possess high energy levels and require constant mental and physical stimulation.

However, their exuberance and need to be entertained make them ill-suited for guard duties. Additionally, their size and energy levels make it advisable to supervise them around the elderly and young children.
