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.
Difference Between a Guard Dog and a Watch Dog
Though sometimes a dog can be both, there are distinct differences between guard dogs and watchdogs. Watchdogs are primarily meant to alert you to the presence of intruders. Often they are selected for breed tendencies, such as barking. Because of this, small dogs that are known barkers can be just as good of a watchdog as a larger breed. Sometimes these dogs are trained for the task, whereas often owners simply rely on the dog's natural temperament to do the job.
These dogs, which may come from typical "watchdog" breeds, guard a person or persons or livestock. Unlike a watchdog which watches an area of property such as your yard, guard dogs will move to protect a person or animal. These dogs are selected for specific breed tendencies and usually are large dogs meant to intimidate. For example, an Anatolian Shepherd will use their size to ward off predators that seek to take down the livestock in their care. Or, a Rottweiler will stand guard over its human family if it perceives a threat to them.
