Hating my fiancee

Question
I have a 2 year old pom. I have had her since she was 6 weeks old. Me and my fiancee have been together for a year and she use to love him. In the past few months when things have become more serious between us, the dog has become more aggersive towards him. Is she jealous or what? Please email me directly.  

Thank you
 Tracy

Answer
If she is intact she may be having hormonal issues and doesn't want him around.  Or she is jealous of him and doesn't want him with you.  He needs to be more assertive with her so that she understands he is not below him in your families hiearchy (sp?).  One way is to have him turn her on her back when she is being aggressive and hold her there for a few minutes or until she lays still with him.  It is a submissive position and reminds her that she is not alpha to him.
He may also need to spend more time with her and give her treats after he rolls her on her belly if she is good.
YOU need to scold her when she does that too as she looks to you as the alpha.

Best of luck.
