Recent photos of Ruby, Polly. Beti and Abbie
From the photos Abbie seems to be the largest, but Beti seems to have more coat than Abbie and Polly. Of course we can't compare with Ruby as she will look very different. The three sisters have darker heads than Beti, it will be interesting to see how they turn out.
Just a reminder, this is Zoe - their beautiful mother and of course daddy O in the bottom photo.
