Not only are dogs tremendously loyal, but they are also very aware of their environments, and protective of those they are loyal too. 

Quite simply, dogs have been used as a means of protection for thousands of years, and have even been consequently bred for this exact purpose. 

With that being said, we are going to dive into why it’s so important to have a guard dog, and what sort of guard dogs are best depending on your personal situation. 

Why Get a Guard Dog?

Guard dogs are tremendous to have around the house for anyone with families, as well as anyone simply looking to add an extra level of safety to their day-to-day life. Guard dogs are trained specifically to watch for, and guard against people (or animals), with their primary role being to keep their human (or their human’s property) safe. 

With that being said, a guard dog is not the same as a watchdog, and understanding the difference is the first step when looking into getting a guard dog. 

For example, a Chihuahua makes for an amazing watchdog due to it’s loud bark and keen senses, but I would not feel safe relying on a Chihuahua to save my life if I was in serious danger. Therefore, a watchdog will let their owner know if a stranger is coming, but guard dogs are typically trained to attack in these situations, instead of simply giving a warning.  

However, there are levels to this as well, as there are a variety of different types of guard dogs, with the main four being; Property Guard Dogs, Personal Protection Dogs, Livestock Guard Dogs, and Military Guard Dogs.

There are many different types of guard dogs. Some breeds are better at different roles.

Property Guard Dogs (Watch Dogs) – Trained to alert their owners anytime an unfamiliar figure is spotted on the premises. They are typically trained to watch over property when the owner is not there. These breeds do not physically attack intruders, but will give verbal warnings such as intimidating snarls. Since they do not inflict harm, property dogs (or watch dogs) make excellent additions to families with young children. 

Personal Protection Dogs – These dogs are trained to exhibit a combination of characteristics found in both watch, and guard dogs. If properly taught, these breeds can attack intruders, but this behavior does not come naturally to them. Personal protection dogs are trained to go anywhere with their owners, and in many different situations.

They typically have better hearing than humans and are usually more aware of their environment. Protection dogs are often territorial and independent, which gives them a formidable presence. Larger dogs make for better personal protection dogs, some classic breeds include; German Shepherds, Boxers, and Akitas because they are very trainable, and look intimidating to potential intruders.  

Livestock Guard Dogs – Trained to perform all of the above roles mentioned of a typical guard dog, but these breeds are highly alert, attentive, and intelligent. Although, they also require more space to roam free, and so it’s for this reason that livestock guard dogs thrive in rural environments, but might not adapt well to an urban lifestyle.

Livestock guardian dogs are often big enough to attack, and are bred to protect livestock from predators. Generally the dog’s ability to guard their herd is instinctive, as the dog bonds with the herd early on. Most of the time they are only asked to guard the herd (not lead or move it), and so many shepherds try to match the colour of the dog with that of the herd.

This way it makes them less threatening to the herd, and harder to identify for the predators. This is likely why most Livestock Guard Dogs are white (same colour as sheep). 

Military Guard Dogs – Trained to charge and pin down any perceived threat upon command. These breeds are favored by the Police or MIlitary as they can apply 750 pounds of pressure into a single bite, tearing through both muscles and tendons.

Often nicknamed “War Dogs”, they are required to be 20 inches tall at the shoulders, and cannot be more than 5 years old. They are trained to not be afraid of loud noises and gunfire, and are used for a wide variety of military purposes.

They may be used to detect harmful gasses and ammunition, as well as bombs, mines, and are trained to attack any oncoming enemies. Despite behaving viciously whenever necessary, military guard dogs are gentle towards their own families and people they trust.
