Some female dogs get Pyometra, a disease of the uterus. It will make their organs fill with pus and they will rupture. Get her fixed. Also, your male dog is fixed, so it should be fine, if you notice a lot of humping, separate them if necessary.
most likely yes. unless he or she is fixed.
NO! If they are both fixed, they CANNOT MATE!

Yes a 6 week old Chihuahua can get swine flu.
