yea, some things are not nearly as bad as some lead people to believe.. a normal sized dog can consume a rather large portion of chocolate and be fine, if not simply vomit.
its like humans and caffeine, a smallish amount simply has side effects on us, but in large doges (multiple grams, sometimes less depending on the person), we will vomit, and in even larger doses we can enter comas or simply die.
we had fed our dog table scraps all the time, it was a treat. if she begged when she shouldn't have been, we simply told her in a way that she understood to go lay down, and she'd listen. give dogs some credit. and they deserve to eat better than the crap that is their regular meal. pellets of junk isn't what I'd want to eat, and I completely support giving dog table scraps as treats every now and then.
i'd feed my dog a piece of chocolate or of something covered in chocolate, but I won't give her more than that, and not regularly either.
too much of anything, for any creature, is rarely a good thing. some people exaggerate the dangers of small treats for their pets simply because an excessive amount if dangerous. guess what, most of the things we eat on occasion could harm us if we ate whatever it was constantly, all day.
since dog's aren't exposed to foods that harm them, they will eat a ton of whatever it is. i think a good way could actually be to expose a dog to 'harmful' food, that way they start to not like it anymore and thus won't consume an amount later down the road that can lead to death. its just like us. we'll eat a lot of something because it tastes good, but if we don't learn that its also deadly, we'll eat enough to kill us. we learn that it hurts us, we either dont eat it or dont eat a lot of it.
