We rescued a 5 year old female. She is a sweetheart, but she has some baggage. We are her 5th home, not real sure why. Though she is always shaking and has some anxiety issues. We have a 14 year old Benji type dog too, she plays with him all day long then at night her dark side comes out and she attacks him if he seeks attention at all. Not sure what to do with her, hope you have great luck with yours.
