Canine Transfusions

I learned something new the other day... Did you know that there are canine blood donors?? That vets have a dog blood donor registry that they can call when they have a patient who needs a blood transfusion?? I had no idea! I guess I never thought about it... never thought about what might happen for dogs if they are injured and lose blood. And... there are cat blood donors too!! I found a UK site that has a registry of potential blood donors. I wonder if Canada has the same thing... or if each vet has their own registry... And doing a bit more research.... there are even horse blood donors! There is something deeply moving about people who would volunteer their pets and animals to help other pets... Human blood donors are one thing... but even there, the number of eligible Canadians who actually donate is very small... And that is helping their own species! But to volunteer your pet to help other pets...  Pets that you might never meet... I wonder if the owners of pet blood donors are also human blood donors??
