I agree with you. My dog and I have a deal. I provide food, water, shelter, and attention, and in return he barks at intruders and licks my face. I can't imagine any circumstance where I would abandon him voluntarily. Of course if I am injured that is another matter. In that case I would have to rely on my family and friends to take care of him.
Ever notice that in the movies no matter what the disaster is and whatever horrible fate awaits the humans, that the family pet always survives?
