What Are You?

This little tiny dog is Coco. We went to visit relatives today and took Little B to meet her. They are almost the same age. I've seen pictures of her but even so, she was tiny! Poor Little B didn't know what to make of her at all. He tried racing around playing but she was having none of it and bared her teeth and yapped at him all afternoon whilst still going back for more. Not sure if she was being territorial or not. Little B was very well behaved and played along, doing his best not to tread on her. I think he was fascinated by her.
