ive never experienced the golden shower of a dog before but my 2cents says to hang a bell on your doorhandle to the backyard. This is how i trained my parents dogs. when i was going to let the dogs out to go potty, i would make them ring the bell, and eventually they caught on, and whenever they needed to go outside they would then in turn ring the bell. they caught on fairly quick. but i never made them ring the bell whenever they were just wanting to play. i used it solely as a potty tool. it worked well and i would highly advise it.
