Yes, This is a question we all may have.. the answer to that is yes they do. In fact, over a dozen different dog blood types have been found so far, and we’ll probably continue to find more types with more research.

Blood types in dogs are genetic. Each blood group is inherited independently, which means that a dog could have any combination of the 12+ blood groups.

This creates variability in which blood types are most common depending on the breed.

Even though there are many dog blood types and possible combinations, the one called “dog erythrocyte antigen 1” or DEA 1 is the most medically important.

What’s the Best Blood Type for Dog Blood Donations?

Dogs that are negative for DEA 1 are preferred for donating blood because their blood can be safely transferred to dogs that are negative or positive for DEA 1.1 or DEA 1.2.

However, DEA 1 negative dogs aren’t truly “universal donors” because a dog may be positive for another blood type that might cause an issue.

To make sure there won’t be a serious immune reaction to any of a donor dog’s blood types, the veterinarian will do another test called “crossmatching.” This test checks the overall compatibility of donor and recipient blood.

What Are the Ideal Qualifications for Dogs Donating Blood?

While in a true emergency, theoretically, any dog could donate blood, some dogs are better blood donors. A few qualifications that they look for.

Over 22Kg (and at a healthy weight for their size; larger dogs can donate a larger volume of blood more easily and frequently than smaller dogs)

Up to date on their vaccines

Healthy (with no heart issues)

Free of infectious disease, parasites and blood-borne diseases

Calm and Obedient

DEA 1 Negative
