The Weight and Size of a Mastiff

The Mastiff is a big and beautiful dog. Many people are afraid of them because of their size.

These canines are very calm and sensitive. They are great with children and they do not sit around and bark a lot as the tiny Chihuahua dogs do.

Before we can decide how much we admire or dislike the mastiff breed let’s find out more about them.

How Much Does A Mastiff Weigh?

English Mastiff

The world’s largest dog was recorded in 1989 to be 37 inches tall and weigh 343 pounds. He was a Mastiff named Zorba.

Don’t worry most of these canines only reach about 120 to 170 pounds for the girls and 160 to 230 pounds for the boys.

An adult female mastiff will stand around 27 inches in height and her male counterpart will be closer to 36 inches in height.

From Puppy to Adult

You will hear a lot of people tell you that by the time a puppy is 6 months of age it will have gotten as tall as it is going to get. A Mastiff does not reach a mature height by 6 months of age. When they are 18 months of age you can get a pretty good guess at exactly how big they will be when they are finished maturing.

At 3 months of age, the puppies will weigh between 16 and 37 pounds. By the time they are five months old, they will weigh between 50 and 95 pounds. By their first birthday, they will weigh between 120 and 200 pounds.

From birth to their full mature size is going to take about 2 years of growth.

You need to be patient with them through their puppy stages and be sure to be firm and consistent with training.
