Mastiff Dog Breed

The Mastiff dog breed is one of the most ancient types of dog breeds. They make great companions for people who can accommodate their big size.

We do not recommend adopting this kind of dog breed if you're living in a small apartment or are a first-time dog owner. But if you're fond of big and loveable dogs, the Mastiff dog breed might be the dog for you.

Male Mastiffs can grow up to 32 inches and weigh between 160 to 230 pounds. On the other hand, female Mastiffs can measure 27 or 28 inches plus and weigh between 120 and 170 pounds. With that said, they are indeed massive dog breeds.

They are described as courageous and excellent watchdogs. But even though they are great watchdogs, they are rarely aggressive and would rather stand their ground, knowing that any strangers or intruders are not winning against them.

These dogs are the essence of what you call a gentle giant. However, some Mastiffs tend to be lazy dogs.

Don't be swayed by their cuteness. You must get them moving every day for the betterment of their health.
