4/13 can`t pass it


It didn`t work at all.


That is because your Dog constructor that you created in exercise 3 is missing.


Hi @csssolver98907 The simple reason is that you need your dog Constructor. A constructor is like a model of your class. So to create your dog contructor...

public void static Dog(){


Happy to help!


I had the same problem, but now it works and my code is the same as yours.
