Trainer Behan says, ``What is newly presented here is the idea that . . . the prey instinct'' is the connecting and underlying theme in all canine behavior. Behan shows how to channel this prey instinct into desirable behavior through play sessions and basic obedience exercises. He also discusses training puppies, calming rambunctious dogs, and handling problem dogs. In the chapter ``Kids and Puppies,'' he offers sound advice on teaching children and dogs to live in harmony. While Behan covers a wide range of topics, some owners will prefer John Ross and Barbara McKinney's Dog Talk ( LJ 5/15/92) . Both books tell owners how to refocus the dog's natural instincts, which inhibit learning, but the simpler, more detailed instructions in Dog Talk will appeal to the average dog owner. --Helen Sondrol, Lincoln Univ.
