Tibetan Mastiffs are muscular, massive dogs, with an intimidating size. They are considered to be the strongest dogs in this world. Tibetan Mastiffs are vigilant and great at protecting their house or owner.
Some people consider Tibetan Mastiffs to be the largest and scariest breed on the planet.
In reality, they are not terrifying. And, they are not the largest.
But how big are Tibetan Mastiffs really? And how do they compare to humans and other animals?
Tibetan Mastiff Size
The Tibetan Mastiff is one of the biggest dogs on the planet. On average, a fully grown Tibetan Mastiff reaches around 24-29″ height and can weigh from 70 to 160 pounds.
The growth process of Tibetan Mastiffs is slow and steady. A Tibetan Mastiff in its final size is enormous, resembling that of lions or bears.
Their size depends on gender and age. These elements lead to differences in both height and weight.

How Tall Is a Tibetan Mastiff on Its Hind Legs?
Tibetan Mastiffs are 35.5”-44.5” long (90-130 cm). When standing on their hind legs, they can reach more than five feet. They can get almost as tall as humans. Some Tibetan Mastiffs are even bigger than humans when standing on two legs.
When Are Tibetan Mastiffs Fully Grown?
Tibetan Mastiffs are fully grown when they are 18 to 24 months old. Some continue to grow until they are five years old. Male Tibetan Mastiffs reach maturity slower than the females of the same breed.
The growth pattern of a Tibetan Mastiff is a complicated subject. People who aren’t familiar with the breed often expect their puppy to significantly increase in size in a short amount of time. Tibetan Mastiffs grow at a slower pace compared to the average growth rate of dogs.
If your puppy isn’t as big as you expected it to be, you can consult a vet and ask for advice. Do not forget that Tibetan Mastiffs are a slow-maturing breed.
How to Predict My Tibetan Mastiff Puppy’s Size at Maturity?
There are three ways to predict the fully grown size of a Tibetan Mastiff at maturity:
- Paw size
You cannot predict exactly how much your dog’s size will increase in time. Remember that every dog is unique and it grows at its own pace.
Your dog’s age is the most important indicator of how much its size will increase. If your Tibetan Mastiff is less than 18 months, it is still growing. The process will slow down from the 18th to the 24th month. Any significant change during this period is mostly muscle.
Another aspect that helps predict your Tibetan Mastiff’s size is its genetics. Depending on how big its parents are, you can approximate your puppy’s growth. If possible, find out this information. Ask a specialist about how large they think your dog will get based on genetics.
3. Paw Size
When a puppy is still growing, its paws look bigger compared to the rest of its body. Check your Tibetan Mastiff’s paws and see whether there is a significant size difference. If so, they’re still growing.
Tibetan Mastiff Species
According to breeders, there are two kinds of Tibetan Mastiffs. One is the Lion Head Mastiff, also called the Tsang-khyi. The other is Tiger Head Mastiffs, the Do-khyi. Between the two, Tiger Heads are larger.
Lion Head Mastiffs have more than 5 cm long hair on their head, ears, and neck. The Tiger Mastiffs usually have no mane or very short hair.
The two species also differ in hair color and the shape of their faces.
Is the Tibetan Mastiff the Biggest Dog in the World?
The Tibetan Mastiff is not the biggest dog in the world. Despite their outrageous size, there is a breed even bigger. The English Mastiff is bigger than the Tibetan Mastiff.
Tibetan Mastiffs are well known for their large height and weight. Even though they reach up to 160 pounds, English Mastiffs are larger. They range from 27 to 35 inches in height and weigh between 200-230 pounds.
