One time I left some eggs sitting out. There were about 9 of them. Instead of throwing them away I decided that I would boil them and feed them to my 2 greyhounds that lived in the house.
BIG MISTAKE! BIG MISTAKE! BIG MISTAKE!
Those dogs farted non stop for 3 whole days. They were low, sizzling farts that I could hear. The sulfuric blast which emanated from their bodies burned my nostrils and my eyeballs. I would walk in the door and the smell would be hanging heavily in the air.
I NEVER fed dogs boiled eggs again.
