He's a 2 year old male Tibetan Mastiff. He's a very rare breed. He's also a great companion with a watchful eye. He's great with children and a great family pet. He requires a lot of space and preferably a fenced in yard to excercise. If you're a beginner at owning a dog he can be a challenge because he's very territorial and has a independent personality. A great investment and asset for true dog lovers.
