Failing to conform to Pet Protocol

I believe my Dog Struct is properly conforming to the Pet Protocol

protocols.swift
protocol Animal {
  var numberOfLegs: Int { get }
}
protocol Pet : Animal {
  var cuddlyName: String { get }
}
struct Dog : Pet {
  var cuddlyName: String 
  var numberOfLegs: Int 
}

Hi there, again! Yes, it conforms just fine and produces no error in Xcode. That being said it's still being really picky about the placement of the colon (once again).

//You wrote
struct Dog : Pet

//They want
struct Dog: Pet 

Hope this helps! :sparkles:
