When Does a Tibetan Mastiff Stop Growing?
Tibetan Mastiffs are one of the largest dog breeds in the world, so they need more time than most other canines to reach full size. It can take up to 18 months for the majority of them. Nevertheless, the largest dog can continue to develop muscle for about 6 more months.
The 3 Factors Affecting the Size of Tibetan Mastiffs
Like humans, not all Tibetan Mastiffs develop at the same rate, and there are many factors that influence their size difference.
- Sex: Your Tibetan Mastiff’s weight and height will be influenced by sex hormones. Male canines are usually slightly larger than females.
- Legacy: An indispensable factor that affects your dog’s ultimate size is their pet parents. Knowing that can help you predict how big your puppy will become.
- Diet: Your dog’s intake during the first year of development will influence whether or not they mature larger or smaller than standard. An overfed puppy may grow larger than the average size, while an underfed Tibetan Mastiff may experience limited growth and end up smaller. It’s crucial to provide your dog with a consistent, healthy diet.
Ideal Diet for Maintaining a Healthy Weight
Tibetan Mastiffs are enormous dogs that require large amounts of food. You can expect to feed them 6–10 cups of dry food daily. If you would love to give them a raw diet, they may need 2.5–7 pounds of organ meat, muscle meat, and bones each day. Senior Mastiffs will need less food, whereas growing pups and nursing mothers require very high amounts. Remember to keep a careful eye on your dog’s size to prevent obesity.
How to Measure Your Tibetan Mastiff
Body length is the distance from the top of your dog’s neck to the base of the tail. When gauging the dog’s body length, place the fabric tape measure where the tail meets the body, then extend it to the base of the neck.
If you want to figure out your dog’s height, put your tape measure at the base of one of their front paws and extend the tape to the tip of their head. You can do it while they’re sitting or standing.
Conclusion
Tibetan Mastiffs make excellent family guardians thanks to their defensive nature, which has been honed over many generations. It is vital to know how your Tibetan canine should grow to be able to understand where they’re at in their development and provide all the things they need at that stage.
This information also gives you a clearer idea of what to expect if you’re considering getting one of these giants as a pet.
