Bigger isn’t always better, but when it comes to finding your perfect canine companion, a teeny-tiny Chihuahua won’t exactly cut it as a jogging partner. These big dog breeds typically tip the scales at 50-80 pounds, although some varieties may skew slightly larger or smaller.

Large dogs belong to six different breed groups (sporting, non-sporting, working, terriers, and hounds), each with its own specific purposes or qualities.

Before adopting a dog, anticipate the time and budget that you can realistically provide for your pet. Owning a dog can cost about $15,000 or more over its lifetime, according to the American Kennel Club.

That money can go towards veterinary visits, grooming, and food, just to name a few preliminary expenses. All large breeds will require more kibble, but a Poodle, for example, will need more frequent haircuts than a Boxer.

A highly active breed will also demand a lot more exercise versus the couch potatoes of the dog world, but all pups deserve basic obedience training, regular walks, and obviously your love and attention.

Airedale Terrier

As the largest terrier breed, Airedales convey the alert, fearless attitude of the group on a supersized scale. They can also carry some of the same stubbornness, but that determination is what makes them such popular and spirited companions.

Weight: 50-70 pounds

Afghan Hound

Sweet and silly, these endearing hounds originated in the mountainous region of Afghanistan. Their silky, fine coat served as protection from the cold at high altitudes, and it requires plenty of grooming.

Weight: 50-60 pounds

Alaskan Malamute

By nature, Malamutes are friendly toward humans. They need a pack leader to set the standard, so stick to a training regimen early on.

Weight: 75-80 pounds

American Staffordshire Terrier

People-oriented Am Staffs are both intelligent guardians and natural clowns. They can be a bit strong-headed and do best when they’re made part of the family.

Weight: 40-70 pounds

Australian Shepherd

With a background in herding, Aussies live to work (or play) thanks to a tireless drive. They’re keenly intelligent and loyal, making them extremely receptive to training. Be prepared to provide an hour or more of active exercise daily.

Weight: 40-70 pounds

Basset Hound

As total couch potatoes, Basset Hounds love to lounge around – when they’re not on a scent that is. Bonus: They’re extremely patient with young children, making them a great family pick.

Weight: 40-60 pounds

Belgian Malinois

These herders are incredibly smart and loyal protectors, which explains why they’re the preferred breed for the military and Secret Service. Understandably, Mals require plenty of exercise and stimulation, and they’re happiest with a job to do.
