I believe it is too early to tell. Also, I wouldn't let the fear of a long coat deter from a good puppy. Some say long coats shed the same if not less. Both stock, long stock and long coats all require routine brushing and she'd a lot - it us just the breed in general. Maybe someone else can help with determining what this pups coat type is.
