I think they're just vanilla and cream canines! It'll be interesting so see how big they get, that will tell a lot about their breed - but they sound too big for most kinds of terrier already, but the Wheaten. Do they shed? (Wheatens don't) They look Shepherdy to me, but the fur's a mystery! And I don't think their raising their hackles makes them a Ridgeback, our Great Dane + 1/4 Lab's fur did that, and maybe most dogs' do, but we don;t notice it as much with shaggier dogs ... Gracie's coat was slicksmooth, so it was noticable on the few ocasions when she was bothered by something enough to react!

Do they have webbed feet?
