The Brown English Mastiff is a gentle giant, but it's essential to understand its lifespan and maturity timeline to provide the best care possible.

On average, a Brown English Mastiff lives for 7-10 years, which is relatively short compared to smaller breeds.

Their large size and potential health issues can contribute to their shorter lifespan.

At birth, Brown English Mastiff puppies weigh around 11 pounds and grow rapidly, reaching 100 pounds by the time they're 6-8 months old.

Their growth rate slows down significantly after the first year, but they'll still need regular exercise to maintain their health and prevent obesity.

A well-cared-for Brown English Mastiff can reach its full height of 30 inches by the time it's 18-24 months old.

Being overweight decreases a Mastiff's life expectancy by 2-6 years, so it's essential to avoid overfeeding.

Routine care costs, such as heartworm prevention, are usually two or three times higher than for a conventionally-sized dog, due to the giant size of the Brown English Mastiff.

Each type of Mastiff has particular health concerns, such as kidney disease or heart disease, so it's crucial to investigate breeders thoroughly and discuss heritable conditions and other specific wellness issues.

As a responsible owner, consulting a veterinarian about the costs of keeping your big dog healthy is a must, especially considering giant veterinary expenses.

At six months old, a male English Mastiff can weigh anywhere from 80 to 110 pounds, while a female can weigh between 60 to 90 pounds.

If you're wondering how big your English Mastiff will get, one way to estimate their size is to look at their paw size. If their paws look oversized next to their legs and body, it's likely they have more growing to do. If their paws don't look oversized, they may be close to their final size.

To get a better idea of how big your English Mastiff will be, you can also look at their parents. Pups rarely outgrow their mom or dad, so if you know how big their parents are, you can get a good idea of how big they'll be too.

Here's a rough estimate of an English Mastiff's weight at different ages:

Keep in mind that every puppy grows at their own pace, so it's always a good idea to consult with your veterinarian if you have any concerns about your English Mastiff's growth.
