//1. modify the Dog class so that it extends the Animal class. Don't redefine any of

//the existing attributes that are inherited from Dog (this is called shadowing

//and id a bad idea).

//2. add a String breed attribute to the Dog class (it should be private)

//3. write a toString method for the Dog class, that prints out all

//the attributes in a Dog (name, age, and breed), separated by spaces. You should use existing methods from the

//Animal class (but don't modify them)

//4. add a constructor to the Dog class that accepts a name, age,

//and breed as arguments, and stores these values.
