@JazzysMom:
I'd spay her. If you are not planning to breed her, what would be the point of keeping her intact?
And, I gotta tell ya, the day one of my dogs growled at my husband over the bed.. or couch or whatever, that'd be the day the DOG was in the other room, NOT my husband. {of course, my dogs sleep in their kennel, but ….}
Ditto! Getting her spayed is a start, but it may not fix this problem. You may need to seek a behaviorst. She is resource guarding you..which can be worse during heat, or it may just be a coincidence that she tried it to this extent during heat..and guess what? It worked for her, she got to keep you and her spot in the bed all to herself, while he went somewhere else. I wouldn't let that happen one more night…she is forming a habit that may not change when she is out of heat.
Does she have a crate, or another room she can sleep in? She will be P!$$ED!! for quite a while, but IMO, you have got to change this behavior.
The other question is, did you contact her breeder? I don't remember what her story is...but if there is a reason the breeder wants to keep her intact, you at least need to contact her before you spay. If not, I would make an appointment for a spay today!!!
