I love to read books about how I can be a better pet owner, and this book gave me a lot of great ideas for my boy, Ozzy.
In Unleashing Your Dog: A Field Guide to Giving Your Canine Companion the Best Life Possible by Marc Bekoff and Jessica Pierce, the authors share the concept of "unleashing" your dog, which means finding ways to give them more freedom. They share how dogs operate within and perceive the world around them, and then give detailed ideas and explanations on how to enhance their lives through smell, taste, touch, sight, and hearing.
I got so many ideas from this book that I can put into action immediately. There was a section on ethograms - described as a "menu of what dog's do" in various situations - and I love the idea of being able to understand my dog's behavior and adjust how I communicate with him based on these ethograms.
What I appreciated about this field guide was that the ideas and concepts are accessible to anyone. You don't need anything fancy or have to live in a specific area to do what's best for your beloved pet. You can enhance their lives right now, from where you are, with what you have.
