Olive girl is a "new" doggie. She belongs to my friend Zack, but we are introducing Olive and Freckles together as Olive is going to be my new addition. I was wondering the same about Olive. I don't know if she is purebred Rott or not? She is a little on the small side. I don't know what she could be mixed with though? So yes, Olive is Freckles new sister. I'll try to get more pics of them as soon as I can. I've had these for awhile but have neglected to post them.
