Tibetan Mastiff
The Tibetan Mastiff is a dog breed from Tibet that comes in medium to large sizes. They have a long double coat, and it quickly sheds odor and dirt. You’ll see black and tan, solid black, deep red, bluish-gray, and pale gold versions of this dog.
People from Tibet used them as flock guardian dogs. They aren’t the best choice for apartments, for they need a spacious yard for activity. They love sleeping during the day and are most active at night. They have a maximum lifespan of 16 years, and are prone to developing hypothyroidism.
