The Iron-clad Golden Dog mainly refers to a breed of Tibetan Mastiff with unique coat color characteristics. Its coat color is black with four golden yellow marks, which are distributed above the eyes, cheeks, forelimbs and tail base. The soles of its feet are also golden yellow, and the head, neck, upper half of the limbs and upper half of the body are also golden. All parts are black, as if wrapped in black, hence the name.

The Tibetan Mastiff is smaller in size and has a lively, smart, curious and brave personality. It is very loyal to its owner. Loyal and child-friendly, it makes a great family pet, suitable for living in the city or country.
