About the Book

Why We Love Dogs, Eat Pigs, and Wear Cows offers an absorbing look at what social psychologist Melanie Joy calls carnism, the invisible belief system that conditions us to eat certain animals when we would never dream of eating others. Carnism causes extensive animal suffering and global injustice, and it drives us to act against our own interests and the interests of others without fully realizing what we are doing. Becoming aware of what carnism is and how it functions is vital to personal empowerment and social transformation, as it enables us to make our food choices more freely—because without awareness, there is no free choice.

Melanie Joy’s book is an important and groundbreaking contribution to the struggle for the welfare of animals. It helps us step outside the box of ‘carnism’ so that we are better positioned to think critically and be a part of the solution, helping to create a more compassionate and sustainable world.

What People Are Saying

There’s plenty of information in this book, and insight, and argument. But the true achievement of Why We Love Dogs, Eat Pigs, and Wear Cows, is that it reminds us of what we already know. With eloquence and humility, Melanie Joy appeals to the values that all of us already have, and have always had. She reminds us of who we are.”

Jonathan Safran Foer

This is a must-read book for everyone who is horrified by the idea of eating dogs, but eats pigs, cows and chickens. Melanie Joy examines the psychological props that make it possible for us to adore some animals and eat others—and kicks them all aside. Why we Love Dogs is written in a clear and lively style, and I’m delighted to see it out in a new edition with a foreword by Yuval Harari.”

Peter Singer

Why We Love Dogs, Eat Pigs, and Wear Cows is groundbreaking. Melanie Joy brilliantly explains why people resist information that would help them make more healthful food choices—and how they can overcome this.”

Michael Greger, MD

Melanie Joy is a thought leader whose work is potentially world changing. A few years from now, ‘carnism’ will be a household term, and how we think about eating animals will be fundamentally altered.”

Maneka Sanjay Gandhi

Few books have done more to change the way I think than Why We Love Dogs, Eat Pigs, and Wear Cows. This is a framework for thinking about how dominant ideologies disguise, protect, and conserve themselves. It will help you see not just the ideology that governs our relationship with animals, but the presence of ideologies that want to remain hidden all over modern society.”

Ezra Klein

Why read Melanie Joy? Because her concept of carnism makes us see things differently. Because she addresses readers with empathy. And because she belongs to a new and exciting generation of committed intellectuals. All of these reasons are good. But there is another one that surpasses them all. You have to read Melanie Joy because what she tells us is important.”

Matthieu Ricard

Melanie Joy is one of the great thinkers of our time. Her excellent Why We Love Dogs, Eat Pigs, and Wear Cows makes a powerful, novel argument for eating plant-based. Her reasoning transcends just health and is a must-read for anyone who wants to make thoughtful food choices.”
