When I was looking for a puppy, before I bought Kalina, one of the breeders told me that she had a beautiful puppy but she wasn't sure if she could be shown yet because she wanted to "wait and see how her top line came in" or something to that effect.

What exactly is a top line and what did she mean by that? Is it something that isn't obvious at so many weeks and how do you know if your dog has a good one?

I'm sorry if this is a silly question - I'm really just wondering.
