I remember one time I was having a REALLY bad day. When I got home I just walked straight to the couch and sat there crying. Codie and Katie just jumped on the couch and literally licked away my tears. After about 30 seconds of that I started laughing and hugging them. It's amazing how they can sense you're moods and just cheer you up! My dogs LOVE me in such a protective way too. One time when Jim and I were arguing, Codie and Katie started growling at HIM (not me) and then Codie nipped Jim on the leg - not hard, but enough to get his point across. That just made me and Jim crack up laughing and ended the fight. Jim wasn't bleeding but he did little teeth marks on his leg - LOL. Codie got him good!
