Blood Donors Required
2 December 2025
Did you know that pets require blood transfusions just like humans? In cases such as severe trauma, snake bite, or extensive surgeries like splenectomies, we may be required to give a blood transfusion. Mauzer the German short-haired pointer recently donated blood for our clinic! Donated blood can be frozen and kept on-hand for emergencies for up to a month.
Dogs have more than 12 blood groups classified as dog erythrocyte antigen (DEA) compared to the 8 in humans. Approximately 50% of dogs are DEA 1-positive and they can receive blood from most donors. Some dogs are DEA 1-negative. While they can donate blood to most other dogs, they run a risk of a transfusion risk if receiving positive blood where they’re own cells will attack the new blood cells. This risk is most likely to occur after multiple infusions.
In order to donate, Mauzer was given a very strong sedation, then 400mls was collected and stored. Mauzer stayed with us until he was fully recovered. Once recovered, he was showered in roast chicken and treats for his bravery.
We are always on the lookout for more canine blood donors! If your dog meets the following criteria and you are interested, please contact the clinic to be added to our donor list.
