The Tibetan Mastiff is an ancient domestic dog breed. On average, it grows to 70 cm (about 27 in.) in height and 80 kg (about 175 lbs.) in weight. This is why the Chinese call it "big ferocious dog." It is now listed as an endangered species. Because of the rarity, the breed is sometimes sold for more than a million USD. Bokhee and Mankang were cloned in 2007 for the purpose of preserving the breed. Sooam was able to clone 11 male and 10 female healthy Tibetan Mastiffs. Then, through artificial insemination (AI) of a cloned male and a cloned female, 7 healthy offsprings were born. This showed that cloned dogs are capable of reproducing and that preservation of endangered species is possible through cloning.
