“Pryor strikingly demonstrates how ethological expertise—knowledge of a subject’s basic biology and behavior—is a prerequisite for success in animal training. Her knowledge of the differing capacities of various species, of their instinctual and sensory processes and their malleability, of how this information can be exploited in relationship to humans, are underlying factors that most other books on the subject ignore.”
