I don't know anything about a "dog" but here it's kinda like putting a weight of shame on you. Haha. Person 1: "I dare you to pull that guys pants down Person 2: "No way! Person 1: "Double dare!" ..... I think that's it anyways. :)
Hi. I'm not sure about the Double Dog Dare, But the first time I heard the, Triple Dog Dare, was off "The Christmas Story," When they "Dared" him to lick the frozen pole outside the school. That was many many many years ago. It point of reference for real... I'm not sure,... I Quadruple Dog Dare you to find it's origin!?! Big Smiles! (I was just passing through some old questions and saw you had asked this and sorry I missed it 1st time around. Talk to you soon! :) You don't have to look it up.
