Dogs have eight standard blood groups (DEA system: 1.1, 1.2, 3, 4, 5, 6, 7, 8). DEA 1.1, 1.2 and 7 are the most important antigens in transfusion medicine. DEA 1.1 antibody causes an acute haemolytic reaction. DEA antibodies to 1.2 and 3 cause a more chronic immune reaction with shortened RBC life span and no systemic signs.Testing is for DEA 1.1. Universal donors should be negative for all three antigens and must definitely be negative for 1.1. Potential donor dogs should be clinically healthy, and on no medication at time of testing.
