On Weibo, owners often seek help from everyone because their dog is injured, hoping to find a dog of the same breed for blood transfusions to help their dog survive the sadness. But in fact, dogs cannot accept antibodies of different blood types from their own. After the first blood type is imported, blood type may change. If blood transfusion is required for the second time, it will become very difficult because the probability of finding a suitable blood source will become very small.

"The most serious case should be the mixture of negative blood and positive blood. When a dog with DEA1.1 negative blood inputs DEA1.1 positive blood, the immune system will take a long time to react in the first case, so there will not be too much reaction. However, when the second time encounters a mismatched blood transfusion, the dog with DEA1.1 negative blood will have a strong discomfort reaction, and even this reaction will be life-threatening.
