Most Hyper Guard Dog Breeds That Thrive With Power
1. Doberman Pinscher

Originally bred in Germany in the late 1800s, the Doberman Pinscher is a breed that embodies strength and speed. They used to work with tax collectors, which was quite a demanding job. In fact, this dog breed was developed by a tax collector himself, and he was greatly impressed by their loyalty.

The male Doberman Pinscher tends to protect properties, whereas the female guards their owners. When it comes to physical appearance, they are quite large and powerful dogs. They are built for speed and endurance, which makes them amazing guard dogs. Their bite force is around 245-305 PSI.
Early socialization and training are important for these strong dogs to adapt to different environments. Pet parents should ensure consistent training as these dogs are highly active and fond of structured routines and mental stimulation, as noted by the AKC. Without enough exercise, their energy can become overwhelming.
2. German Shepherd

German Shepherds are considered to be one of the best guard dog breeds due to their intelligent and brave nature. From protecting owners, to children, to livestock, these working dogs have never failed to impress anyone. Their appearance is more than enough to scare anyone who’s passing by the streets.

This dog breed requires proper training, which helps them to become aware of what their owners are expecting from them. For experienced pet parents this should be an easy task, but new owners should not expect instant obedience. These fiercely loyal dogs bond closely with family members.
One bark from these German Shepherds is sufficient to shake an individual from head to toe. Their bark really means business, and any burglar breaking into a house would think a million times before doing so. Their bite force ranges from 238-291 PSI, giving them control and strength in protective situations.
3. Rottweiler

Known to work with the Roman Empire and herd cattle, this is one of the best guard dog breeds due to their incredibly loyal and affectionate nature, as per WebMD.
They are also famous for looking after the cattlemen’s money. The cattlemen would easily tie their money bags around their necks, making thieves run away.

They require early socialization and basic obedience training. With the right efforts, these large dogs with black and thick coats turn out to be calm and devoted companions. After the 1900s, they have been known as police dogs, because they lost their main work (guarding cattle) in the mid-1800s.

These working dogs have a strong bite force of 328 PSI, allowing them to cause severe damage with their teeth. They also have a muscular body, which will make anybody think twice before approaching them. The Rottweiler is one of the most protective breeds you’ll find in the world.
4. Saint Bernard
Ranked among the best guard dogs, the Saint Bernard has been prominent due to their massive size and deep loyalty. These gentle giants with hidden protective instincts were originally bred for alpine rescue work, but their watchfulness and strength also make them good family pets.
Though they are not very hyper in nature, they require daily walks, strong obedience training, and firm boundaries. This working dog is a perfect addition to active families. They are quite loving with children, and typically patient, but can be territorial when necessary.
Their bite force is estimated at around 195-220 PSI, not exactly a high score, but their imposing size can cause a person to shiver. Clean and fresh water should be given to them at all times for their health maintenance, and they also need a balanced proportion of nutrients.
5. Cane Corso
These protective nature dogs were originally bred in Italy for battle and hunting wild boar. When it comes to personal protection for families, they are remarkably watchful and vigilant. To put it into simple words, the Cane Corso is a strong definition of power and control.
Pet owners should acknowledge that they require experienced handlers, early socialization, and excellent leadership. Avoid using aversive methods; they can make your dog aggressive and create unnecessary stress. Note that they are easily trainable as they have an eager-to-please attitude.

With a bite force of around 700 PSI, they are included in the top strongest biters in the canine world. While this gentle giant is loved by their owners and children, the Cane Corso, with its striking square-shaped head and powerful jaws, can come off as pretty tough. According to Orvis, they are also called ‘catch dogs’.
6. Great Dane
Meet the Great Danes; these guard dogs were developed to hunt large game in Germany. While they aren’t actually traditional dogs, many people keep them for the purpose of protection. Due to their imposing size, they often come across as scary, and can make even the daring think twice.
Early training is crucial for the Great Danes as new people can appear as a threat to them. They’re calm but still need daily exercise, early training, and room to move comfortably. Their loyalty and protective nature shine when they feel their family is threated.
Their bite force is estimated at around 238 PSI, supported by their massive size and jaws. However, please be aware of their stubborn nature; they are also quite slow to mature. It can be challenging for some pet parents to deal with them, but with willingness and dedication, it can become manageable.
7. Belgian Malinois
The Belgian Malinois was originally meant to herd livestock, but later on, they became good companions to many. Due to their strong work ethic, they are ideal guard dogs for police work and the military. They also have an affectionate temperament towards their owners.
Compared to other pets, this strong dog is extremely intelligent and loves to learn new cues, tricks, and training. For example, policemen often go for a Belgian Malinois puppy as they can be trained to detect and sniff out bombs, gas, and drugs. Avoid leaving your child alone while they are on a training period.
The bite force of a Belgian Malinois is between 200 to 320 PSI, and they can do serious damage with their jaws in threatening situations. This strong dog thrives with mental stimulation and regular exercise. They make great biking, running, and hiking companions, which is ideal for adventurous individuals.
