Awe... poor girls! You never know what environment she came from, and maybe it was out and out survival for her there, and she just acted on instinct. I hope Nicki is ok. She hasn't been aggressive with any of the kitties, has she??

I hope you will find another friend for Nicki, and if not now since she might be shaken and scared of another new dog, in a little while.

Big hugs to you guys!
