Giant guard dog breeds can be both fascinating and intimidating. Why the interest in giant guardian dogs? To some people looking for protection, bigger is always better. Many would-be intruders are far more intimidated by the sheer size of a dog than anything else. A large, muscular dog that announces by his very presence that he is in charge is often enough to make most intruders decide to pick an easier target.

List of Giant Guard Dog Breeds

As you scan the following list, you'll notice that a number of breeds known for their guard dog tendencies (such as Doberman Pinschers) are not included. You'll also notice that some of the biggest overall breeds (such as Great Danes) are also not on this list. That is because this list is meant to represent only the largest breeds commonly used as guard dogs. Take a moment to learn about some of the breeds that fall into this category.

  • Cane Corso - A powerful Italian Mastiff, the Latin root of this breed's name means "protector."
  • Dogue de Bordeaux - AKA the French Mastiff, this is a massive and impressive beast.
  • Fila Brasileiro - This dog is absolutely fierce toward strangers and requires confident, strong leadership.
  • Great Pyrenees - A quiet family companion, the Pyrenees will spring into action when a threat appears.

Characteristics of a Natural Guard Dog

There are common hallmarks shared by nearly all the breeds that have been bred and trained to work as guard dogs. These include:

  • A natural instinct to protect
  • Physical strength and agility
  • Steady temperament
  • Courage
  • Confidence
  • Keenly alert to surroundings

Of course, these characteristics are just the base on which a reliable guard dog is built. Since most of these dogs are quite powerful in their own right, early training is crucial if you want to help them develop to their fullest potential.

Don't Confuse Aggression with Guarding

It's sometimes assumed that any aggressive dog can make a good guard dog, but that's not really the case. The very best guard dogs are capable of independent thought, and they protect the people they serve out of a sense of loyalty and affection for them. A good guard dog thinks its way through any dangerous situation, listens to its owner's commands and only uses the necessary strength and aggression needed to deter or subdue an intruder.

Responsible Ownership

Owning one of these giant guard dog breeds is a huge responsibility. Make sure your dog receives proper training from an early age. Begin with socialization and obedience training, and then enroll your dog in professional guard dog classes. This will give you the most control over your pet, and help ensure the safety of your family as well.
