1902.  At councils of great importance, a dog-feast was formerly held, and to refuse to participate would anger the Indians and defeat one’s wishes. But if, when the plate of dog was offered, one put a dollar on the plate and passed it to one’s neighbor, the latter took the dollar and ate the dog. From this custom the slang phrase of politicians, “Eat dog for another,” originated.—Bishop Whipple, ‘Lights and Shadows,’ p. 260.
