I would think that spaying them will help.....but, also you need to show your yorkie that this is unacceptable behavior.
I have had this issue with two of my females. What has worked for me is "time outs" just like you would do with a child. If only one is acting out, that one goes to a room by herself. If both are fighting, each one goes to a room by herself. I only leave them alone for a couple of minutes and when I let them out, I watch them closely and say "No" in a firm voice when they start to "posture". Works like a charm. It was frequent for a while and I felt they would never be able to live together....but, this only happens now once in a while and I get them back on track.
Until you get this straightened out, I would not leave them alone together! Good luck! |
