Anyone else find equating pets and animals with humans to be rather strange?

73. It depends.

Humans and dogs are animals who can, if they are lucky, get benefits from life. Other things being equal, a dog's suffering is just as bad as human's suffering. Suffering is suffering. As for survival, many factors are relevant to a comparison. Assuming the child has a good shot at a long, decent human life, I would think it likely that he or she would have more to lose by dying than the dog (since a dog's life span is relatively short) and so that would count in favor of saving the child. But other things being equal, I would save a young healthy dog with a bright future before I would save a brain dead human or a human that is terminally ill and will die soon anyways or even a very old human who has already had a long, full life.

Anyone who thinks that just because they are human their wellbeing is more important than a dog's is a human supremacist and that is not any better than being a white supremacist in my book.
