What to read after Adam's Task?

In it Vicki Hearne asserts that animals that interact with humans are more intelligent than we assume. In fact, they are capable of developing an understanding of “the good,” a moral code that influences their motives and actions. Hearne’s thorough studies led her to adopt a new system of animal training that contradicts modern animal behavioral research, but—as her examples show—is astonishingly effective. Hearne’s theories will make every trainer, animal psychologist, and animal-lover stop, think, and question.
