Oh, no worries!! Soooooo much can change from that age to maturity. I've seen dogs that looked like crap at one year, but looked really good at three.
Your girl is a pretty puppy and IMHO she looks well put together. I really like her topline.
My girl is going through a gangly stage. She's built more like a performance cardigan then a show cardi, but I'm sure we can get a Ch. on her.
Our first puppy match is this coming Spring.
