I wouldn't give it to them to be sure.
Yes my dog eats more popcorn than I do. There stomachs have stronger acid than ours do therefore they can eat things that would make us deathly sick. My dog has also eatin two pairs of my kids underwear and somehow passed it. The first six months of his life he was hooked on eating plastic toys. Seriously you should have seen all the little bits of plastic in his stool. I'm not sure how it didn't cut his insides up but he is healthy as a horse 2 yrs later
Although it is not good for dogs to eat human food, it is ok if they eat a few pieces now and then
