我如何实现这种类型的OOP结构？

class Animal:
    def __init__(self, name, species):
        self.name = name
        self.species = species

    def make_sound(self):
        pass

class Dog(Animal):
    def __init__(self, name, breed):
        super().__init__(name, "dog")
        self.breed = breed

    def make_sound(self):
        return "Woof!"

my_dog = Dog("Buddy", "Golden Retriever")
print(my_dog.name)  # 输出: Buddy
print(my_dog.species)  # 输出: dog
print(my_dog.breed)  # 输出: Golden Retriever
print(my_dog.make_sound())  # 输出: Woof!
