NataleeRose,do you ever get alone time with the dog?Does your husband work or leave the house,hang out with friends or anything and leave the dog with you? If so,those could be your times to enjoy it.My husband has an emotional support dog and I enjoy the time I get with it but when he's home I'm ok with it being "his" dog.

I understand that you are extremely upset over it,is it that you really love the dog that much and so badly want to spend time with it or is it that he doesn't want you to?If your marriage is as good as you are saying it is and there's no other problems going on maybe you need to just let this one go and let the guy have and enjoy his dog,especially if it helps calm him.
