Since you want specifics, veganism isn’t actually about animals, its about sentient beings. I wouldn’t eat a cow or a dog or a human, because they each have the capacity to suffer and the desire to live. Anything that has this capacity is off the table for vegans. Even bugs, while obviously being less sentient than a cow or human, still demonstrate this in some capacity. So no, I just eat plants and fungi. Technically I could eat a jellyfish or even an oyster (although vegans debate it), since this capacity has not been demonstrated by them. Why would I harm others for my own pleasure/sustenance when there is an alternative, especially an alternative that is cheaper, healthier, and far more sustainable?
