Finn hasn't been sick, yet, thank goodness. So, I'm not sure. But, I've noticed he is very watchful of me when I am. It was so cute...I have been off and on with this congestion and cough and sinus crap...he's usually right next to me...but, when he is downstairs, if I have a sneezing or coughing episode, he races up the stairs to see if I'm all right.
