BLOOD TRANSFUSIONS Dog VS Cat
Did you know cats and dogs both have blood types, but how we match them is very different?
DOGS:
- Dogs have over a dozen blood types, but the most important is DEA 1.
- The first transfusion for a dog is often safer even if the blood type isn't known yet, they don’t naturally carry antibodies against other dog blood types.
- BUT once they’ve had a transfusion, typing and crossmatching becomes very important for future ones!
CATS:
- Cats only have three main blood types: A, B, and AB, but here’s the twist—
- Cats are born with antibodies against other blood types, meaning an incorrect transfusion can be life-threatening even the first time.
- For cats, matching blood type every time is a must!
