Why we love dogs, eat pigs, and wear cows

Why we love dogs, eat pigs, and wear cows, is a question that should be asked to every american. Eating dogs and animals that are consider "inedible" is wrong in every americans mind. We wouldn't eat dogs because they are like our friends. Dogs have emotions, we play, run with them, feed them when they are hungry, take them to the doctor when they are sick, we treat them like any other human being. But has anyone ever thought that cows, pigs, and chickens have emotions too? Even if it may be odd to find people treating chickens and pigs like pets but in some countries this is what people are doing. Then, do people in those countries find us weird for eating their pets? I believe that there is no correct way of eating, or what is correct food to consume. What everyone eats throughout the world is different depending on their difference in lifestyles and cultures.
