Chihuahuas and Sickness

I have been so sick this whole week, sleeping away most of the entire week....along side of me have been my two little chihuahuas holding steady to me as if they knew what was wrong. I don't know if they just have a sense about them that they know when you don't feel well but they are extremely smart dogs. Does your chihuahua do something special or different when you don't feel well? Do they cuddle up to you? Heck, my chis have been so close to me that I haven't had much room to myself. One thing about chihuahuas....they are so loyal!
