I would like to know why I get this error: dog.sayLegs() should return the given string - note that punctuation and spacing matter. // tests completed

Tell us what’s happening:

Your code so far

let dog = {
name: "Spot",
numLegs: 4,
sayLegs: function() {return "The name of this dog is:" + dog.name + ".";}
