Is popcorn good for dogs? LOL umm I mean would it hurt them if they ate it!? I'm sure it's not good for them... heck it's really not good for use... but my daughter found the left over popcorn from the movie we went and saw yesterday... and she threw the bag away but it was empty... I saw Odin eating something and though he was done... I smelt his breath and well DEFINITELY popcorn! I know it's not really the best thing for us... but I'm wondering if it's something I should worry about or if he'll be okay. I'd say he probably ate about 1 cup of it.
