The Castro has a courageous temperament and exceptional courage, as well as being resilient and, because of its excellent stamina, once in a fight it is often a bloody one until it is completely won or completely defeated (seriously injured or killed in battle). Very loyal to his master, he is very docile to the rest of the family, loves to play with children and is tolerant of their excesses. Castro is also very intelligent and easy to train. However, the temperament is rather stubborn, so it is important to be aware of the methods and to give more guidance.
