What would you do if your spouse treaded you like a dog?

Start to act like one?

I Would have to say that you two need to consider some better communications. Ask her to sit down and talk, not argue, don't scream and yell or point fingers at each oher, just ask her way she does X or why yo do Y.
If you can't figure out a way to commuicate with each other there is no point in being in a relationship. And if you have shildren what's this teaching them, That by yelling or treating someone with disrespect they will bow down or listen to you.

And perhaps it's not just her treating you as a dog, maybe your action have made her relate you to a dog for some reason, There still is not excuse for poor treatment of your spouse but there must be a reason.
Of coarse there are always two side to a story and you are voicing your here, but where is she voicing hers, and do you want those people to know about it.
If you are having a serious problem then i might also suggest some Therapy, wheter it's family, or Marriage counseling and if you have shildren I would suggest Family counseling, becuase you don't know what effect this has already had on the children and the kids can often add some insite to the problems that maybe your not seeing.
Well that's the best answer I can give you and it's more advice then an answer, so take it for what it's worth, I've been married Happily for 23 years now and 5 children later I think I know what good communications are.
Best Regards to you and yours.

Dump their a** immediately.

Even if you thought you loved them, nothing on this earth is worth losing your dignity for. EVER.

I would roll over and get my belly rubbed.

i would run away and take some time off and think whether i'm better off without him....

I dunno about you but I'll use the most extreme psychology on her til she'll be crying pitifully, " Mercy ! Mercy..Oh God...will somebody help me." Then I just rub my hands gleefully and have a nice cup of coffee. Good riddence ! Oh yea, 'coz there's no physical evidence on her body to report me to the authority.
