I think hormones are probably the cause. My Katie gets very aggressive when she is in heat and extremely loveable when she is pregnant. I would just watch them closely and not leave them alone together for awhile and see if she settles down. It sounds like she may be a little jealous also if she is trying to get at the other dog while on your lap. Good luck with this as I also have one that is a lap dog and doesnt want to share it. LOL |
