I have a problem with Add Methods After Inheritance

Tell us what’s happening:

I don’t see what i’m missing here

Your code so far

function Animal() { }
Animal.prototype.eat = function()
     console.log("nom nom nom"); 

function Dog() { }

// Add your code below this line
Dog.prototype.constructor = Animal; 
Dog.prototype = Dog;
Dog.prototype.bark = function(){

// Add your code above this line

let beagle = new Dog();

beagle.eat() // Should print "nom nom nom"
beagle.bark(); // Should print "Woof!"

Link to the challenge:

Is this how the sample in the lesson declared the constructor and protoype ?

Thank you for reflection sir.
