I don't know why my code cannot be compiled for the struct of Dog

protocol AnimalType { var numberOfLegs : Int { get } }

protocol PetType: AnimalType { var cuddlyName: String { get } }

struct Dog: PetType {

}

protocols.swift 
protocol AnimalType {
  var numberOfLegs : Int { get }
}

protocol PetType: AnimalType {
  var cuddlyName: String { get }
}

struct Dog: PetType {
}
