I hear some footsteps by the door, and I bark excitingly, and I run over to the door, my tail wagging. I know that you are coming home, and I miss you so much, even though our owner isn't home. When you come through the dog door, I bark again with excitement!

Magnus! Welcome home, I missed you!

As you walk in the door, my facial expression changes to worry.. you seem upset, I can sense your stress but I have no clue why

Hey, are you okay..?
