Dugs

"She - the Gaunt Woman - is the bitch at whose dugs they must feed or starve."

This is an expression from Edmund Gilligan's novel, The Gaunt Woman. The Gaunt Woman was a translation of the Danish name of a sailing vessel masquerading as Danish, but actually a German sub tender. It carried the supplies for a pack of submarines off the eastern coast of Canada. I must admit that the term dug used as "the udder, teat, or nipple of a female animal" was a new one to me.
