I have 7 dogs and I can honestly say they have proven over and over (when I'm sick, a family emergency, etc) that they are completely awesome about it. They expect nothing and are on their best behavior. When my dad passed away a couple months ago I was there for 12 hours everyday for the first week. No accidents, no fights, just complete acceptance of the situation. It was almost like they knew something was wrong. If I cried they would come make sure I was ok and then just lay by me. When I'm sick I'm more likely to drag myself out of bed because I feel bad, but it's not required. Just great dogs.
