Dugao and Castro, fierce dogs.

Du Gao is a hunting dog. He is lively, frank, humble and friendly, and he can realize his strength without too much barking. It should not be aggressive, which should be borne in mind. Its sense of dominance makes it constantly compete for territory with other same-sex dogs, especially male Du Gao. As a hunter, it is smart, quiet, brave and fearless.

Castilo is an excellent watchdog. Castillo is brave, with extraordinary courage and toughness. Because of their excellent endurance, once they fight, they often fight bloody battles until they win a total victory or are completely defeated (seriously injured or killed). Castro's ancestors fought bears, even lions, tigers and other large beasts in the ancient Roman arena. Castro's most glorious history is that he once served in the ancient Roman army, accompanying his escort master to kill people directly on the battlefield. Very loyal to the host, very docile to other family members, like to play with children, and tolerant of children's excessive behavior. Castro is also smart and easy to cultivate. But the temper is stubborn, so we should pay attention to methods and guide more. However, castelo's dominance is quite strong, especially for male dogs. Obedience must be cultivated and run through the dog's life. It is not difficult to cultivate castelo's obedience, but it must be done, otherwise the consequences may be very serious. Castro is wary of strangers and can show moderate friendliness, but he will not be enthusiastic or attack for no reason. But for those who may pose a threat or infringement to their owners, it will immediately launch a ruthless attack.
