Dating back thousands of years ago, the Tibetan Mastiff is the result of local Mastiff and Molosser breeds. The Tibetan Mastiff is a natural guard dog and protector at heart, however, this breed had a time era of misfortune when they were tied up and left outside to be hungry and become aggressive, as the owners back then felt that this was better.

Their coat is a double coat, very long and extremely thick. Their coat is available in black, brown and blue gray, with our without markings and shades of gold running through their coat.

Special Notes

Please fully educate yourself about the Tibetan Mastiff prior to adding one to your household to ensure you are able to provide life long physical and finanical care to your new family member. This breed requires a properly fenced in yard or proper fitting harness and leash while outdoors at all times. This breed is prone to hip and joint issues, skin infections and allergies, ear issues, CIDN - a fatal condition that runs in their genes, and thyroid problems. All dogs originate from wolves (Canis Lupus). Each breed of dog was originally created by mixing different breeds together in an effort to bring forth certain characteristics. Once a breeder has created acceptable “breed characteristics” within their bloodline and these “breed characteristics” have shown to be reliably reproduced in the offspring for three (3) generations, the bloodline may be upgraded from the category of “foundation stock” to “pure-bred”. The same “pure-bred” breed standards vary from different continents, countries, territories, regions, breed clubs, and canine pure-breed registries depending on the goals of their breeders. Dog DNA testing companies can have accurate results for a specific bloodline of a small colony of dogs. However, there are tens of thousands of different bloodlines in the world which have not yet been tested for marker baseline results by Dog DNA testing companies as of 2017. For this reason Dog DNA testing companies do not guarantee the 100% accuracy of their breed lineage results and will also show different marker results for the same pure-bred breed in different continents, countries, territories, regions, breed clubs, and canine pure-breed registries depending on the goals of their breeders.
