Thanks for your reply! I've been reading up on breeds and trying to figure her background out. Someday I'll probably do a DNA test.

Luna is a 2 year old that I rescued 2 months ago. She was spayed 3 months ago and her mother is a Yorkie but father unknown. She weighs 13 lbs. She barks a lot but when I tell her to stop she starts growling instead. Thoughts?
