When you have an unplesant day how do your Animals respond.

Depending on what is wrong with me, my dog acts differently. If I am sick the dog attaches himself to my butt and I can't move. He lays with me, licks my face all the time, and is a general pain because he's trying to stay with me. If I'm upset and crying he will lick my tears away. Now that I have gotten pregnant he dont come very close to me lol. He knows what happened the last time I was like this, I brought something home that took some attention away from him. Now he knows that another thing is coming to take more attention away.
