A guard dog makes us feel secure and doubles as a beloved pet. I had a 120-pound Great Pyrenees and always felt safe with my big, beautiful girl. Canines have super olfactory and auditory senses, so they know before we do when someone approaches our home and family or is coming toward us outdoors.
Your sweet companion is also a protector. Even little dogs are vigilant and tell us if someone’s arriving.
Most of the best dog breeds for protection are fearless, watchful, and strong. Guard dogs need proper training at a young age so you have control over their behavior and they don’t cause any unintended harm.
Also, consider exactly what you want from a guard dog to determine which dog breed is the perfect pup for you because some are more of a watchdog than a guard dog, and some are more aggressive than others.
As with any working dog, natural guard dogs know when and how to do their jobs, and when they aren’t on duty, they switch to their family pet personality. Many guard dogs are affectionate pets. As always, dog ownership means giving your canine love and affection.
Both watchdogs and guard dogs bark loudly, and some have a bad reputation for being aggressive, but they have a nice temperament with their families and just need training to learn manners like all dogs. If you’re outside, they will also warn you of the threat of wild animals that sneak up on prey (in this scenario, we are the potential prey).
Here are the 15 best guard dogs that are naturally wary and loyal pups and will keep you safe, amuse you, and generally make your life better because they are adorable and loving and make great pets.
1. German Shepherd Dog

German Shepherds (GSD) are one of the best guard dog breeds as well as one of the most popular dog breeds in the US because they are excellent guard dogs and wonderful members of the family. Think Rin Tin Tin.

Large dogs are good for people with active lifestyles, especially those who enjoy hiking and even just walking. Long legs are better for those activities than little, stubby legs.
Bullmastiffs should be kept in your home or in a fenced-in area to avoid confrontations with other animals. They don’t bark unless they have something important to say. They are very big and bred to pin down poachers.

The Thai Ridgeback makes a great guard dog. Like the more common Rhodesian ridgeback, they have a line of fur that goes in the opposite direction of the rest, creating a ridge on their back.

The Chesapeake Bay Retriever fetches dead ducks during hunting trips. They are energetic, athletic, tireless, and agile. They will protect you, and they also need to be stimulated mentally.

They have been used to chase prey and bray (the noise canines make when tracking an animal), bark at trees that small mammals ran up to hide from hunters, and are famous for herding — so they are versatile and always helping their people.
