Marion Schwartz is a research assistant in the department of anthropology at Yale University.

Drawing on chronicles, ethnographies, archaeological reports, myths, biology, and a rich array of visual materials, Marion Schwartz investigates views about dogs in a wide range of native societies in North and South America. She discusses the early domestication of the dog and looks at how hunting and gathering peoples relied on dogs to help with the hunt and to transport food and goods. She provides details about the eating of dogs for ritual purposes or as a dietary staple. She describes how dogs were associated with the afterlife, where they functioned as guides or guards, and how dogs were buried in tombs or were sacrificed to the gods in many cultures. She examines pre-Columbian art to see how the dog was portrayed and the various meanings attributed to it. The book concludes with a description of the fierce war dogs brought by the Spanish to wreak havoc among the Indians - dogs unlike any the New World had ever seen - and how traditional societies reinventented their relationship with dogs after the arrival of the Europeans.
