Tibetan Mastiff
This dog breed is most common among the nomadic cultures in Central Asia. It is an ancient breed which is really large and muscular, and is common for its dark coat. Though it is called a mastiff, it is actually not a mastiff. It can reach up to 83 centimeters in height with weight ranging from 45 to 75 kilograms. Due to their size, they are capable of confronting huge predators like wolves and leopards if they are in pack.
