The French mastiff, also known as the dogue de Bordeaux, may look intimidating, but this powerful dog is amazingly loyal and affectionate. It can weigh up to 140 pounds and stand up to 26 inches tall at the shoulder.

The Anatolian shepherd is an ancient Turkish breed, which, unlike many large breeds, has an impressive average lifespan of 13 to 15 years. This dog can have some aggressive traits, so it’s not always ideal for families with small children. The Anatolian shepherd can weigh up to 140 pounds and reach a height of 32 inches.

The most famous Newfoundland is probably Nana from J.M. Barrie’s Peter Pan (the play, not the 1953 Disney version), and it’s no wonder Barrie chose this breed to watch over the Darling children. This dog is a gentle giant and makes a wonderful family pet. The Newfoundland can weigh up to 150 pounds and stands at 29 inches tall.

Intelligent, independent, and surprisingly quiet, the Neapolitan mastiff is a big dog with a fearsome reputation. It’s often used as a guard dog because of its fiercely protective nature and large size. This muscular dog can weight up to 150 pounds and stands up to 31 inches at the shoulder.

For anyone who loves big dogs, it doesn’t get much better than the majestic Leonberger. This German breed is patient and affectionate like the Newfoundland, but the Leonberger can reach an even greater size. A male can weigh up to 170 pounds and stand over 31 inches tall at the shoulder.

The name pretty much says it all: The Irish wolfhound originated in Ireland and was once used for the purpose of wolf hunting. Though it may sound fierce, this breed actually adapts very well to family living if properly socialized. The Irish wolfhound can reach up to 180 pounds and stands up to 32 inches tall at the shoulder.

Scooby-Doo may have popularized the Great Dane as a domestic breed, but there are plenty of other reasons to love this towering German breed. In terms of height, this dog is hard to beat: The tallest-known Great Dane was measured at an incredible 44 inches at the shoulder. On average, the dog measures 32 to 34 inches and weighs between 150 and 180 pounds.

The Caucasian Shepherd is a gorgeous Eastern-European breed that’s best reserved for experienced dog owners who excel in obedience and socialization.

The Caucasian Shepherd can weigh up to 220 pounds and stand over 30 inches at the shoulder.

The Big Daddy of them all, the English mastiff is a giant dog lover’s dream. Standing 36 inches in height and averaging 200 to 230 pounds, this is definitely a dog that will keep the burglars away.
