var events = require('events');

function Dog() {
}

util.inherits(Dog, events.EventEmitter);

// This statement will override the current `prototype`, thus losing
// the methods from EventEmitter.
Dog.prototype = {
  fetch: function() {
  }
}

// This one will work though
Dog.prototype.fetch = function() {
}

// Question is, if my `Dog.prototype = {}` has lots of methods. I don't
// want to rewrite all of them to be like `Dog.prototype.METHOD_NAME`..
// how do I get around this?
