This little one is the surrogate pup. Peanut, mommy Schnauzer does not realize this is not one of hers. As they get older I do see this little one off to herself more. Are they ostrasizing her? I don't know but I don't let it go on. She is put back in amongst them and they play. No one is mean to her and she is doing wonderful. She is going to be a tiny thing.
