Mom Is Sick and Brutus Doesn't Like It

I have the flu, and Brutus just doesn't get it. My bones hurt, I am freezing to death, I can't keep anything "down", and all Brutus wants to do is play. I can't even tell you how many times I've been hit in the head with a ball or bone. Aren't dogs supposed to instinctively know when their owners are sad or sick?? Or, is that just the older and wiser dogs that know these things. Daddy needs to come home from work soon. :((
