Q. In an emergency, could you receive a blood transfusion from the family dog or some other animal?
A. Not on your life. As you know, blood types and compatibility are critical issues.

Blood types refer to the different molecules on the surface of red blood cells, which if mismatched can trigger a fatal immune reaction.
