This is Polly, she's looking great too - it still looks like both puppies are neck and neck, I'd have been happy with either I think.
I just thought I'd do a little poster of the sisters together.
You can see that Beti is a little more stretched on her hindquarters, and pushing a little more forward, giving her generally a little bit more of an alert posture. To be honest, I can't see anything other than the posture on the day to compare with.
