Did you know that among the many pet dogs that people live with day and night, there are several aggressive and dangerous breeds, which are the pits (including the American pitterBulldog, Staford Summer Bulldog and American Staford Summer Bulldog), Japanese Tosa, Newpoliton and other three dog breeds. These three kinds of dogs are all fighting dogs and are naturally aggressive. Pitbulls will attack when they see a dog. There have also been cases where the dog turned his head and attacked the owner when he could not bite;

Newpoliton was once a The guard dogs of the Italian Mafia will obey the master's orders, but they will kill people when they are fierce; Tosa is also a fighting dog, and there are few people in the country. Some people raise it for dog fighting or gambling. At present, most foreign countries classify these three fighting dogs as dangerous or aggressive dog breeds, and their breeding is restricted. Regulations in Taiwan require that these three types of dogs must wear masks, be accompanied by adults, and be led by a leash no longer than 1.5 meters before entering or leaving public places. In Hong Kong, restrictions on keeping dogs are strictly enforced, and these three types of dogs are not allowed on the streets and in public places. On the contrary, some large dogs, such as the Western Tibetan Mastiff dog, the German Wolfdog, are mistaken for a fierce dog by many people. In fact, Tibetan Mastiffs are fierce to strangers, but they are very loyal to their owners and are not neurotic; German Wolfdogs are the best dogs in the world, well-trained, and will never attack humans for no reason.
