my pup was living outside in Colorado at 6 weeks - 8 weeks when I brought him home. Although he slept in a crate with his litter mates, they all lived in temps down to 15 degrees at night with nothing but their natural coats.
in your case I think it partially depends on where the breeder has raised your pup and how thick it's coat is. But I'd suspect that walks with a 7 week old pup will be very short and it will let you know if it's cold (by shivering).
