Can we? I've read that we can't pass the common cold to them, but we CAN pass the flu to them since, hostorically, all forms of the flu stem from what was originally Flu A, or avian flu, which came from birds.
I have a sinus infection and my doc told me it was contagious until I was a day or so into the meds. My dog is always very close to me and I breathe on him and pet him and whatnot.
