just do not do any of your things to do around the house... just stop, do not mow clean etc... and when asked when you are going to do all those things very politely respond "when you people clean those piles of dog squeeze as we had agreed" it works.
I do all of the yard work and car maintenance, help with dishes etc, whatever I can do to help, after my first kid was born my wife stopped helping me with yard work... its a lot of work and recently I just had it... I stopped cleaning up the fence from kudzu and weeds... when it became too horrendous my wife grabbed the gloves and the weed whacker... took her like 4-6 hrs to finish. I think she got the message; I said thank you and gave her a massage at night
