They are all prescreened before coming to Hemopet so that they can help ANY dog who needs blood products. brandi797 7 years As a veterinarian, I can assure you, Greyhound blood is NOT compatible with all blood types, canine OR feline! Cats have two blood types, A and B. Dogs blood types are based on the presence (or absence) of various dog erythrocyte antigens (DEA); the most important being DEA 1.1 and 1.2. A "universal canine donor" is both DEA 1.1 and 1.2 negative. Greyhounds are used because they have a higher percentage of red blood cells per volume of blood, known as "packed cell volume" (PCV). While most dogs have a PCV of 40-50%, Greyhounds tend to have a PCV of abour 66%.

I work at a vet hospital and own a greyhound who is a blood donor. Greyhound blood is not necessarily compatible with all dogs, and certainly isn't compatible with cats. There are something like 8 different types of blood for dogs, greyhounds do have a higher likelihood of having what amounts to a "universal" blood type, but it varies per dog. I know several people who have had their greyhounds tested and they aren't universal. Even if the dog is universal, they still need to be cross-matched to give to another dog. As for cross-species blood donation, that simply isn't true.
