I'm not sure what is happening.
protocol AnimalType {
var numberOfLegs: Int { get }
}
protocol PetType: AnimalType {
var cuddlyName: String { get }
var numberOfLegs: Int { get }
}
struct Dog: PetType {
var cuddlyName: String { get }
var numberOfLegs: Int { get }
}

You do not need to define the get attribute on the variables inside the struct. That is there by default. ;)
Your code would look like this.
protocol AnimalType {
var numberOfLegs: Int { get }
}
protocol PetType: AnimalType {
var cuddlyName: String { get }
var numberOfLegs: Int { get }
}
struct Dog: PetType {
var cuddlyName: String
var numberOfLegs: Int
}
Keep up the great work! :)
