2. Tibetan Mastiff:
Dog attacks are traumatic and in some cases, tragic events. Tell a dog owner that his dog is dangerous and you will probably get rebuffed. The sad truth is that some dogs, like their wolf and jackal relatives, are prone to aggressive tendencies. Should you rub one up the wrong way unwittingly, the consequences are disastrous. t is only when these dog breeds are untrained that they launch unexpected attacks. all dogs can be trained to be disciplined and balanced. The Tibetan Mastiff, an ancient Tibetan breed, was a livestock guardian. This dog needs the firm hand of an experienced owner who knows how to set boundaries. Introduce him to your neighbors and their dogs early. Engage him with exercise and activities, or he will become a destructive nuisance. Many Chinese cities have banned their residents from owning him.
