Is a fierce dog like castelo suitable for domestic use?

Many people like fierce dogs, such as Castro, Du Gao, Caucasus and so on, but I personally think Castro is more suitable.

Reason one: Castillo is not picky about food, and basically he eats whatever you feed him.

Reason 2: Castillo dog recognizes the Lord. When you take it out for a walk after dinner, it will follow you closely and collide with your eyes from time to time, as if it knew in advance where you were going next.

Reason three: Castillo is very clever. During the training period of Castro's puppy, as long as you give a password, it can remember it more than five times and respond quickly when you give the relevant password in the future.

Reason 4: Castillo is very stable. Compared with Rottweilers, castelo is stable and doesn't like barking. As long as Castro goes out with you, he won't cause you any trouble, and he won't see other breeds of dogs inexplicably excited.

Reason 4: Castro's explosive power and endurance are super strong. Castro's explosive power is very strong, and endurance is undoubtedly the first. Before the owner may get hurt, it will quickly protect the Lord.
