Well, the hound brothers got hold of a bag of un-popped popcorn and apparently ate it all. I assume they both got some--all that was left was paper bag and plastic wrap. Any ideas on how harmful this may or may not be? I have not fed them dinner as of yet--not sure what to do on this. They both seem to have sturdy stomachs, but I don't want to create bigger problems. Anyone with any advice?
