What is the average weight of a mastiff?

Answer 1

On average, a healthy newborn Mastiff puppy may weigh anywhere between 13-22 ounces at birth. According to its size, the weight of the Mastiff male at 3 months should be between 22.9 and 30 kg. At 6 months, the Mastiff male weighs on average between 41.7 kg for the smallest individuals and 55 kg for the largest individuals.

Answer 2

Average weight for a mastiff is around 150 to 200 lbs. However this number can vary based on the type of mastiff. Many dog breeds that you may not see as mastiff's are in fact, a mastiff breed.

Answer 3

Of course a bull mastiff's weight would vary with growth and age. For instance, I had a 5-6yr old that was approx. 180lbs.

Sorry, but that's not right. I have a mastiff and he's only two years old. She weighs about 240 pounds. They can pretty much weigh alot at any age. :)

Answer 4

Well, my female mastiff is two years old and weighs app. 190, but she is very large so she is probably above average.
