Most Famous And Protective Dog Breeds

1. Akita

We all have heard about Hachiko, an Akita famous for its loyalty and devotion towards its owner. Akita is a muscular and large dog of ancient Japanese lineage. It is known for its affectionate behavior towards its loved ones.

While Akitas are playful and loving with their family members, they are naturally suspicious of strangers and intolerant of other animals. These independent thinkers are hardwired to protect their owners.

They are highly alert and intelligent, and make wonderful watchdogs and guard dogs, thanks to all these traits. These heavy-boned Spitz-type pooches are quiet and fastidious. Akitas gladly share the silly side of their personality with their friends and family.

In Japan, people consider them a sign of health, happiness, and long life. Akitas have moderate grooming needs and are prone to certain health problems like hip dysplasia and thyroid issues.

2. Bullmastiff

These large and muscular guardians were originally bred as guard dogs. Bullmastiffs are athletic, brave, and fearless. They are very docile and all lovey-dovey with their owners, but if an intruder or another male dog is in your yard, their protective instincts will kick into gear.

Bullmastiffs are famous for being gentle and loving to their human companions. These great family guard dogs will try to stay by your side as much as possible and are prone to suffering from separation anxiety if neglected for too long.

Although Bullmastiffs are not as large as their close cousin, the Mastiff, they have an intimidating presence. Nicknamed “Bullies” or “Gamekeeper’s Night Dog,” Bullmastiffs require early training and socialization like any other protection dog breed.

Bullmastiff is a brachycephalic breed with moderate exercise needs. PDSA recommends a minimum of two hours of daily exercise, which could be split into a few walks off-lead in a fenced area.

Their intelligence and ability to think independently mean they have a strong-willed personality, which can make training difficult.

3. Doberman Pinscher

Dobermans were originally bred as guardians, so they possess an instinct to guard. One of the most protective dog breeds, the Doberman Pinscher is the canine world’s nobleman. Its sleek and muscular body, black coat with rust markings, and fearlessness make it an excellent guard dog.

With proper training, these extremely intelligent pooches make fiercely loyal companions who will be great at following your commands. Doberman Pinschers’ intellect, naturally protective nature, and athletic way of moving have made them popular all around the world.

These enthusiastic and active guard dogs have lots of energy to burn. They need one and a half to two hours of exercise every day to stay happy and content. Lack of adequate activity can lead to destructive behaviors.

4. German Shepherd

German Shepherd ranks fourth in the American Kennel Club’s list of most popular dog breeds, as mentioned by the AKC. These large and agile dogs are highly intelligent and fearless. They are famous for their role as military and police dogs.

German Shepherds are confident dogs with a strong work ethic. Their bravery, courage, and stamina make them one of the best guard dogs. GSDs’ protective instincts and alert demeanor also mean they are amazing protection dogs.

GSDs are among the smartest breeds and make fiercely loyal companions. They are highly trainable and eager to please dogs who have been protecting their owners for centuries. This athletic breed requires lots of physical and mental stimulation.

Do You Know? Two German Shepherds named Rin Tin Tin and Strongheart are so famous that they have got stars on the Hollywood Walk of Fame.

5. Giant Schnauzer

Having an imposing size and strong bodies, Giant Schnauzers are the largest of all Schnauzer breeds. They are quite good-natured, affectionate, and loyal dogs. Their muscular and substantial bodies are suited for the role of a guard dog.

Bold and vigilant, Giant Schnauzers were bred to serve as protection dogs. They have retained their guarding skills to date and make excellent guard dogs. Giant Schnauzers loudly bark to alert their human companions to perceived threats.

They can even turn aggressive towards interlopers on their property, explains Orvis. Their dense eyebrows and harsh beard accentuate a keen and clever expression. Popular because of their intelligence and eager-to-please nature, Giant Schnauzers possess some territorial instincts as well.

This, combined with their highly energetic personality, makes them unsuitable for first-time owners. Giant Schnauzers have lots of stamina, and they don’t mind play sessions several times a day.

6. Rottweiler

The descendants of large Mastiffs, Rottweilers are confident guardians known for their deep sense of loyalty and loving personality. Thanks to their history as guard dogs of the Roman Empire, Rotties are naturally inclined to protect their family members.

Physical strength and muscular build make them appear quite intimidating to predators and intruders. They are popular because of their glistening black coats with rust markings, intelligence, and strong protective instincts. Their booming and loud bark alerts the owners and scares away potential threats.

Being naturally wary of strangers and having an impressive bite force of 328 PSI, Rottweilers have earned a bad reputation as aggressive dogs. However, they are not inherently aggressive. In fact, their playful and gentle nature makes them well-suited for family life, explains PetPlan.

However, a Rottweiler may not be the right breed for homes with small children. Rottweilers are one of the smartest dogs out there. They grasp new commands easily and make effective military and police dogs.

7. Tibetan Mastiff

Tibetan Mastiffs were bred to guard royalty; they served as protection dogs for Tibetan nomads. These gentle giants are popular because of providing effective protection and loyalty to their humans. One of the best guard dogs, the Tibetan Mastiffs are recognized by their lion-like mane, thick coat, and large size.

These muscular and powerful pooches embody lots of strength and independence. Their territorial nature, strong-willed personality, and guard dog instincts require early training and proper socialization. These courageous and watchful canines do not like strangers.

Tibetan Mastiffs are affectionate with children, but their size makes them a better choice for families with older children who are more sensible. These big, fluffy dogs do not require extensive exercise and focus more on work-related tasks like guarding their territory.
