Tibetan Mastiffs are huge dogs with a threatening appearance. If you have a TM puppy, you may be curious how big they can grow.
Is The Tibetan Mastiff The Biggest Dog In The World?
However, keep in mind that the phrase ‘biggest’ might be misleading, as it can refer to height rather than the overall size. The Tibetan Mastiff is clearly one of the world’s largest dogs, but it is not the world’s largest dog. The English Mastiff, which stands between 26 and 36 inches tall and weighs between 200 and 230 pounds, is considered to be the largest.
When TMs stop growing, they are approximately 60 to 78 cm tall and weigh 75 to 160 lbs. Males, like several other dog breeds, are typically larger than females. Males weigh from 90 to 160 lbs while females weigh between 70 and 125 lbs.
There are certain elements that affect their full size, which is why we see such a huge variety between them. Genetics and hereditary factors, general health, and aspects which you are accountable for and can control, like as food and nutrition, are the most important.
Bear in mind that although owners and veterinarians anticipate their Tibetan Mastiff reaching full heights and weights in 12-18 months, certain breed lines may take longer. It’s not uncommon for TMs to grow to their full size over several years.

Here’s all you need to know about the size and growth rate of T Matiffs:
- During the first few weeks, a TM puppy will gain 2 to 8 oz per day, eventually increasing to 1 to 3 pounds each week. In terms of height and length, Tibetan dogs generally grow much faster in their early months.
- At three months of age, a male TM should weigh from 33 to 48 lbs. They weigh from 63 to 91 lbs. at 6 months somewhere between 90 and 140 lbs. at a year.
- A female Tibetan Mastiff, on the other hand, weighs from 27 to 41 lbs. at three months of age. At 6 months, they weigh around 73 to 74 lbs., and at a year, they weigh around 76 to 79 lbs.
Living with the Largest Dogs in the World

Having to deal with an injured or sick dog may be a terrifying experience for any dog owner. When your pet is in need of medical attention, your first goal should be to get them the care they require as soon as possible. But what if you are unable to lift your dog or they are afraid to visit the veterinarian?
The first step is to be prepared to go through this with your dog at his own pace. If you need to be in the vet’s clinic quickly, this isn’t the time to talk to him about the problem. Avoid moving an injured dog’s neck, head, or spine when transferring or transporting them. When carrying them to the car, keep their head level if they have been confused or frightened.
If you’re bringing a puppy in for regular check-ups, you might want to consider putting it in a crate so that both you and your dog are safe during the trip. This is because you never know what your dog is capable of, so even if he’s simply sitting in the passenger seat, he could suddenly take the steering wheel from you.
