This INFURIATES ME as I think when we first started looking for another yorkie, we were being scammed by the woman that sent us pics of the yorkies she had for "sale". She sent us a collage similar to the one you posted, and when we asked for more specific pictures of the females (as that's what she said she had left), she never got back to us about that and dodged just about every question we asked...plus wouldn't let us come to her home.
I don't get how these people can live with themselves, especially scamming people out of money when all they want is to be a loving yorkie parent. It makes me SICK.
