Dogs do not need to be matched for their first blood transfusion because they do not have innate antibodies in their blood and do not experience rejection, so they do not need to be matched for their first blood transfusion. However, it is limited to the first blood transfusion, and all other cases of blood transfusion require matching. Dogs may experience fever, shortness of breath, convulsions, seizures, red rashes and other symptoms after blood transfusion, and the transfusion should be stopped immediately if abnormalities are found to avoid life-threatening conditions in dogs. As for the other common pet cat, it is more delicate than the dog. There are three main blood types of cats, and they are born with antibodies in their blood. If the blood type is not correct, a severe clotting reaction can occur, which can be life-threatening.
