Once protectors of livestock, palaces, and monasteries in the Himalayan mountains, today, this sizeable dog enjoys life as a great family pet. If you’re looking into getting a Tibetan Mastiff puppy, you might be wondering how big they get and how much space will they need.

How Big Is a Tibetan Mastiff Dog?

Tibetan Mastiffs are large breed dogs, ranging in size and weight depending on their gender, and possess a thick long double coat that contributes to their mammoth size.

On average, they’ll stand at around 60-70 centimetres and weigh between 54-68 kilograms. Like many other dogs breed, males will be larger than females.

With female Tibetan Mastiffs standing at 61-71 centimetres and weighing in at 34-54 kilograms, male Tibetan Mastiffs will stand between 66-76 centimetres and weigh a whopping 41-68 kilograms.
 

At What Age Does a Tibetan Mastiff Reach Its Full Size?

As a giant dog breed, a Tibetan Mastiff puppy needs more time than other large dog breeds to grow and will only reach physical maturity at around 12 months old.

You’d think this is where it ends, but most Tibetan Mastiff puppies will continue growing in size and weight till they’re around 18 months old. Some will reach their full size here, while others may continue growing slowly until they’re five years old.
 

What Is the Ideal Weight For a Tibetan Mastiff?

According to the American Kennel Club (AKC), the breed standard for a fully mature male Tibetan Mastiff should be between 40-68 kilograms, and for a female, it’s 31-54 kilograms.

Excessive weight gain can be a significant health problem with this breed. They require a good deal of exercise and high-quality dog food to ensure they’re maintaining a healthy weight.
 

How to Make Sure a Tibetan Mastiff Isn’t Overweight

You should be weighing your Tibetan regularly to ensure they’re within the optimal range for their weight. If you’re above the standard range, always consult your vet for advice on how to manage your dog’s weight better.

Like all dogs, Tibetan Mastiffs thrive best with a healthy diet, regular exercise, and a good routine.
 

Ensuring Your Tibetan Mastiff Grows Properly

As puppies, Tibetan Mastiffs have a faster growth rate in terms of length and height in the early months; weight only follows when they’ve reached an adolescent age.

Female Tibetan Mastiffs will reach their full size before males – some females can take up to 3-4 years to be fully grown, while some males can take 4-6 years. It is all a matter of genetics, nutrition, health, and physical activity.

Male Tibetans’ growth spurts are as follows:

  • 13-20 kilograms at three months
  • 24-38 at six months
  • 36-61 kilograms at one year.

For females, their growth spurts are approximately:

  • 11-18 kilograms at three months
  • 18-27 kilograms at six months
  • 27-50 kilograms in one year.

The best way to ensure your Tibetan reaches their full potential is to understand their diet and exercise requirements for their age.
 

FAQs

What is the life expectancy of a Tibetan Mastiff?

Tibetans have a life span of 12-15 years.

What health concerns do Tibetan Mastiffs have?

Tibetan Mastiffs are a relatively healthy breed, but they can suffer from minor ailments like hip dysplasia, thyroid deficiencies, and canine inherited demyelinating neuropathy. Due to their fast growth rate, they can also suffer from panosteitis (growing pains).

How much space do Tibetan Mastiffs need?

These are large dogs, so it’s important to note that your puppy will grow to take over much of your home. This breed is not recommended for those with minimal space inside and outside their home.
 

Final Thoughts on Tibetan Mastiff Size & Weight

The ancient Tibetan Mastiff was once a guardian of great monasteries, and today, it sits among the top picks for popular family dogs and performers in the show ring.
