When it comes to taking good care of the things we love, perhaps nothing is as important as our pets, Peter says. As our animal friends and as living creatures, pets depend on their human companions for shelter, food and, of course, affection. Peter talks with dog trainer Tamar Geller about taking a positive approach to building a healthy relationship with your dog. Then, Peter talks with radio talk show host Mark Levin about his book Rescuing Sprite: A Dog Lover's Story of Joy and Anguish.

According to Tamar, dog owners can either train their dogs to be fearful and submissive pets, or they can train them to be happy, joyful and well-mannered members of the family. She says her training method emphasizes positive reinforcement instead of using punishment to control a dog's behavior. The result is a healthy relationship based on mutual respect between pet and owner. "Your dog listens to you because you are a benevolent leader, because you make them feel that they are safe with you," she says.

Known for his outspoken opinions on political and social issues, Mark says he put aside plans to write a political-themed book in order to tell the heartwarming story of his family's dogs instead. The book recounts the story of a rescued dog named Sprite, his battle with illness, and how the family coped with his passing. Most of all, the book speaks to the deep bond that can form between man and man's best friend. "This book's about humanity, it's about love and grief—and it's not something I expected to write," Mark says.
