me too...haha you have never been hungry?
Dogs will eat scraps straight out of a garbage can.
that isn't that weird...
Many will eat their own crap too.
Nothing that you said addresses my point, that dogs do not know science, and yet, will smell at food to assess it's value, and also at whomever is offering it to them, to assess his or her intent/vibe. And yet HUMANS, who are allegedly more intelligent, will eat whatever is called "food" in their language with no such appraisal stage.
"Ah, those endless forests, and their horror-haunted gloom! For what eternities have I wandered through them, a timid, hunted creature, starting at the least sound, frightened of my own shadow, keyed-up, ever alert and vigilant, ready on the instant to dash away in mad flight for my life. For I was the prey of all manner of fierce life that dwelt in the forest, and it was in ecstasies of fear that I fled before the hunting monsters."
