java - Aggregates & Polymorphism Patterns

Question

I was curious as to how if polymorphism should be used with CQRS.

class Animal {
  public void animalSound() {
    System.out.println("The animal makes a sound");
  }
}

class Pig extends Animal {
  ....other fields
  public void animalSound() {
    System.out.println("The pig says: wee wee");
  }
}

class Dog extends Animal {
  public void animalSound() {
    System.out.println("The dog says: bow wow");
  }
}

Say there is objects like this. Pig and Dog both inherit from Animal. But Pig has a few more fields than Dog or other Pets do that is unique for it.

What are good patterns for polymorphism being using with Aggregates in CQRS?
