The World’s Strongest Dog Breeds

When searching for the best family dog, you might think that a smaller pup is the way to go. But actually, some of the strongest dog breeds, which are known for their ability to serve as guard dogs, also make for great companions.

Though strength doesn’t always equate to size, our list of the strongest breeds tends to overlap with the best large dog breeds. These burly cuties weigh well over 100 pounds, with many ranging between 120 and 150. However, their brawn is just one aspect of these pups. These gentle giants are also known for their calm demeanor, over-the-top intelligence, and ability to do work if you need it.

As always, it’s important to do a lot of research before you adopt a pet. Many dogs are great for families with small children, while others, especially due to their size, may not be. Some are ideal for first-time pet owners, and some are better for people with more experience. You should also take into consideration how much exercise and space each pup needs to make sure your lifestyles match up well.

Whichever adorable breed you choose, the next step is picking out a sweet girl dog name or fun boy dog moniker, and spoiling your new pet with some top dog toys.

Saint Bernard

A male Saint Bernard can get up to 180 pounds and is known for being extremely protective, according to the American Kennel Club. Its massive size and muscular physique is why it makes the list of strongest breeds. Saint Bernard also makes for an excellent family dog.


While the average Mastiff can stand about 30 inches tall and weigh up to 230 pounds, they are said to be gentle giants. These dogs are powerful, yet affectionate and do best with older children, according to the AKC.


These dogs work hard and play harder. They are historically known as working dogs, and their muscular exteriors prove it. However, they are also extremely playful and always up for a good game of fetch. In the right setting, they can make excellent family pets.

Great Dane

According to Hill’s, Great Danes fall in two categories of breeds: Working and Guardian. And although massive, they are also playful and affectionate and will welcome tons of cuddles.

Rhodesian Ridgeback

These dogs are skilled hunters and are known to be powerful athletes as they have both a muscular build and speed. But don’t let them fool you: they tend to have a gentle temperament.

Irish Wolfhound

If you’re looking for a graceful yet muscular pup, you’ve found your match. The Irish Wolfhound just looks intimidating. It is actually too sweet to be a guard dog. These pups can be great family dogs, but due to their large size, supervision is needed when they are around small children.

German Shepherd

German Shepherds have one of the most powerful bites, which is why the breed is often used for law enforcement, military and protection. But don’t let that deter you from adopting. They make excellent family pets and are wonderful with children.


Though they have a large and powerful stature, Newfoundlands are also known for their sweet temperament. They are eager to protect and get along well with children and other dogs when trained and socialized properly.
