15 Top And Best Giant Dog Breeds:

You won’t believe the size of the largest dog breeds in the world! Although there is no well-defined height or weight at which a dog breed would be officially classified as the largest, it is accepted by some experts to consider especially large breeds of dogs, those that are heavier than 45 kg.

Thinking about becoming a big dog owner or curious to know what are the biggest dog breeds? Well, let’s take a look at the 5 largest dog breeds in the world.

Anatolian Shepherd:

The Anatolian Shepherd Dog is a breed of a large dog that originated in Anatolia (Turkey) and was further developed in America. The Turks themselves call dogs of this breed Kangal. This breed may be over 6,000 years old.

Anatolian Shepherds can be 80 cm tall and weigh 68 kg. However, their thick coat makes them look even more powerful and heavy than they really are. This is not a shepherd dog. The breed was bred to be independent and strong, to protect the herd of its owner without the help of a person in vast areas from wolves, so communication and training of the dog as early as puppyhood is necessary.

They often live up to 11 years, which is usually 3-4 years longer than other breeds of their size. They can act as a nanny for children.

Black Russian Terrier:

A type of dog developed in the USSR in the late 1940s and early 1950s as a working or military dog. The Russian Black Terrier is thought to be the offspring of roughly 17 different canine breeds.

Guys can weigh up to 60 kg and stand 72 to 78 cm tall at the withers; females are slightly shorter and lighter. The Black Russian Terrier is a calm, fearless, and self-assured canine. He is incredibly intelligent and well-educated.

It can live up to 14 years on average, which is quite a long lifespan. This dog is generally in good health, however, they can occasionally be predisposed to specific hereditary conditions, such as hip or elbow dysplasia.


The bullmastiff has a broad, folded head and a rather short, square muzzle. The nose is round and the eyes are dark hazelnut. The ears are V-shaped and hang down. The tail is set high, situated at the posterior end, and reaches the hocks of the dog.

The bullmastiff has a broad, powerful, and square-looking body. Short and simple to keep, the coat might be fawn, reddish-brown, or brindle in color. The male bullmastiff weighs between 50 and 59 kg and grows to a height of 60 to 70 cm. Females typically weigh between 45 and 54 kg and range in height from 60 to 65 cm.

Bullmastiffs are sweet and affectionate with family members. Their generally calm and relaxed disposition makes them good dogs for families with children who are reasonably well-behaved. However, the bullmastiff’s laid-back attitude towards family members will likely change when strangers intervene. These dogs tend to be wary of people outside of the family.

Despite all this family-focused fidelity, the bullmastiff is not naive. He can think independently, so his training can be difficult. They may also be less tolerant of animal family members than they are of their owners. You should pay attention if you consider incorporating a Bullmastiff into your animal family.
