what are the functions that can be called on ANY object of class Pet, Dog and Rock.

what are the functions that can be called ONLY on object of class Dog.

What does the print function display and does it display the same items for the objects of all these three classes

What does the getLifeSpan function return and does it return the same string for the objects of all these three classes
