I have killed three dogs in Minecraft. The way to get a dog is to find a wolf, and then feed bones to the wolf until red Valentine’s hearts blossom forth from the wolf, and then it is your dog. It will do its best to follow you wherever you go, and (like a real dog) it will invariably get in your way when you are trying to build something. ... I felt bad each time, while of course fully realizing that only virtual entities were being killed. Surely some of the sorrow I felt was imported from the real world, where I am fond of dogs and do what I can to avoid drowning or burning them. I could not be said to have developed a meaningful relationship with my virtual dogs, but I was pleased to see them each time they caught up with me, and I was a little sad to realize they wouldn’t be getting in my way anymore. I think I was right to feel at least a little bit bad about killing them.
