I've been giving my dogs button eggs. I only have 1 hen laying right now. So every 3 days I give the dogs (3 dogs) a raw egg as a treat. I swear they are learning to count and sit and stare are my on the 3rd day. LOL!

Not worth getting your dogs sick. I'm sure after that many days at 100 it's full of bacteria. If it's something I wouldn't eat, I wouldn't give it to my dogs. :) If others do and dogs aren't getting sick, I'd say luck which is always subject to change.
