Make sure the Dog object conforms to the Pet protocol.

What's wrong?

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

protocol Pet : Animal {
var cuddlyName: String { get }
}

struct Dog : Pet {
  var numberOfLegs: Int
  var cuddlyName: String
}

Could be a spacing issue when you are conforming to a Protocol or Class there is no need for the extra space

protocol Animal {
    var numberOfLegs: Int { get }
}

protocol Pet: Animal{

    var cuddlyName: String { get }
}

struct Dog: Pet {

    var numberOfLegs: Int
    var cuddlyName: String
}
