Animal Blood Types Groups
Dogs Need Transfusions Too!!!
Currently, eight to twelve or more canine blood groups are recognized,
depending on which studies one consults. In all cases, these various
blood groups are organized and categorized under the DEA system. The
acronym DEA stands for Dog Erythrocyte Antigen. Blood groupings, or
blood types, among dogs are specified by the letters DEA, followed by
some number(s) denoting which DEA system antigens are present on the red
blood cells of the dog in question.
For all canine blood group systems other than DEA 1, the red blood cells
from a dog can be either positive or negative for that blood type. For
example, a dog could be DEA 3 positive or DEA 3 negative. The DEA 1
system is different. It appears to have three separate subgroups: DEA
1.1 (also known as A1) , DEA 1.2 (also known as A2) and DEA 1.3 (also
known as A3). A dog's red blood cells can be DEA 1.1 positive or
negative. Further, DEA 1.1 negative cells can be DEA 1.2 positive or
Cross matching and Transfusions in Dogs
In contrast to human beings and domestic cats, dogs do not seem to have
any naturally occurring antibodies to other blood types. This has
several important clinical implications:
Blood cross matching, which is performed to detect antibodies in the
recipients blood to antigens in the donor's blood, is less important in
the dog, and may not have to be done at all if the recipient dog has
never received a transfusion before (which frequently is the case).
An initial blood
transfusion into a dog that has never before received a transfusion is
unlikely to cause a transfusion reaction.
Antibodies to foreign blood groups may develop in a dog within days of
receiving a transfusion. So, if a dog has received a transfusion before,
it should be cross matched to insure blood compatibility before
receiving a second or subsequent blood transfusion.
In the veterinary literature, most of the emphasis on canine blood
typing is placed on the blood groups DEA 1.1 and DEA 1.2. Evidently,
these are the two most antigenic blood groups among dogs. Since DEA 1.1
is the single most antigenic blood group, most veterinarians recommend
that DEA 1.1 positive dogs be avoided as general use blood donors. Note,
however, that DEA 1.1 positive dogs can donate to other DEA 1.1 positive
dogs with no problem. DEA1.1 negative and DEA 1.2 negative dogs are
often referred to as “universal donors.”
Your dog must be 12 to 18 months old, they'll have some tests and a full
check up, they must be fully vaccinated, wormed and flea free and
obviously in good health.
