Many novice owners of Tibetan mastiffs are surprised by the growth of their new dog. The most frequent complaint of the owners is that their Tibetan mastiff does not grow as it should. They expect a big dog and they want it to grow faster.
Veterinarians who are not familiar with the breed also add fuel to the fire, because they do not understand that the breed does not fit into the “standard” schedule for dog growth and development. According to the norm, male mastiffs weigh from 45 to 73 kg and grow from 66 to 76 cm, but it takes a lot of time and patience for a dog to grow and reach that size, since the Tibetan mastiff is a slowly maturing breed.
On average, healthy newborn puppies of the Tibetan mastiff weigh from 400 to 600 grams. This weight depends on many factors, the main one of which is the number of puppies in the litter.
The growth rate of the puppies in the first weeks can be 50 to 150 grams per day, the larger puppies can increase from 0.5 to 1.2 kg per week. Again, the set depends on many factors, including the quality and quantity of milk and the number of puppies.
It is important to keep in mind that the largest puppy in the litter is not necessarily the largest when it matures.

Puppies under 1 year
Tibetan mastiff puppies receive their new homes, usually at the age of 2 to 3 months. It is imperative that the new owners plan a general medical examination of their new dog.
Maintaining a personal puppy growth schedule will help you and your veterinarian better understand the specific nature of your pet’s growth.
Most owners and veterinarians expect medium and large breeds to achieve final results and grow at 12 to 18 months, but this does not apply to the Tibetan mastiff. Special attention should be paid to the genealogical lineage and the specific breed lines, since some lines may mature more slowly than others.
The best option to have an idea of what to expect from your dog is to discuss its history and its pedigree with the breeder.
In general, the females reach, on average, the total maturity at the age of 3-4 years, while the males mature 1-1.5 years more. Your dog’s eating attitude, general health and average growth rate will help determine how your dog will develop over the years.
Large dogs can sometimes experience a disproportionate development of individual parts of the body. The head or tail of a dog may seem too big, which is a normal process.
Puppies older than one year
Monthly growth rates can decrease significantly after the first year and can often be almost imperceptible. You may notice that your MT goes through periods of accelerated growth, depending on the seasons.
With the onset of warm weather in the spring, seasonal moult begins for mastiffs, and food consumption at this time is usually lower. The colder months of autumn, on the other hand, force dogs to consume more food before the beginning of winter.
