Regarding the issue of raising Tibetan Mastiffs, some people have made suggestions to use them as police dogs, but it has proven to be unfeasible. The reason is very simple. Tibetan Mastiffs are ferocious, loyal, bloodthirsty by nature, and are not afraid of any target. However, this is an advantage and a disadvantage. After the Tibetan Mastiff identifies the target, there are only two results. The first is to be killed by the enemy, and the second is to kill the enemy. The crazy Tibetan Mastiff will not even listen to the owner's words, so this is doomed to the Tibetan Mastiff's fate. The execution ability is very poor, so it is not suitable to be a military dog. Also, one of the Tibetan Mastiff’s eyeballs is white. This is the origin of the word white-eyed wolf. In addition to appearance, it mainly describes the Tibetan Mastiff’s disowning of its relatives when it goes crazy. At this time, anyone who dares to stop the Tibetan Mastiff is an enemy, and the owner is no exception. Therefore, it is not suitable to be a police dog if it loses its mind easily.
