The task simply asks to create a struct named Dog, but the error shows it also needs a property 'numberOfLegs' of type String, which was never mentioned before. Is there something wrong with the task itself or is it my code? thx.
protocol AnimalType {
var numberOfLegs: Int { get }
}
protocol PetType: AnimalType {
var cuddlyName: String { get }
}
struct Dog: PetType {
}

Treehouse TeacherIt's odd that the error is saying you need String for numberOfLegs as it should be an int. The PetType is going to require a string with a "cuddlyName" (whatever that is). And because it inherits from AnimalType it's going to need a returned Int for the number of legs. See my code for clarification:
protocol AnimalType {
var numberOfLegs: Int { get }
}
protocol PetType: AnimalType {
var cuddlyName: String { get }
}
struct Dog: PetType {
var numberOfLegs: Int{ return 4 }
var cuddlyName: String{ return "Snookums" }
}

5,237 PointsThanks Jennifer!
And the error asked for type Int, not String. That was a typo, sorry.
