Dogs Have 13 Blood Types

That's a lot considering that:

  • Humans - 4
  • Horses - 8
  • Cats -3
  • Pigs -3
  • Cows - 9

About 60% of dogs are either DEA 1.1 negative or DEA 1.1 positive.  In the other 40%, blood type varies greatly.

Is blood type breed specific? Yes and No. A majority of individuals within these breeds have the same blood type:

  • Doberman
  • German Shepherd
  • Rottweiler
  • Great Dane
  • Golden Retriever
  • Greyhound
  • Dalmatian

But other breeds have great variation.

Interestingly, even when blood type is breed-specific in one location, it may differ from country to country. For instance, one blood type exists only in dogs from Australia, primarily in the German Shepherd population.

Scientists don't have an explanation for the many different blood types in mammals, including dogs and humans. Blood types likely evolved more than once, probably as immunity to pathogens. Different blood types may protect us from different diseases.

One of my readers told me that wolves are type AB negative.  I'd like to know more about blood type in the wolf.

 For more information ask your veterinarian. Also, you can read about canine blood types here.

  1. Interesting subject really....I'd not given much thought to blood groupings in dogs, as I've never had to deal with transfusion issues with my dogs thus far, but it does raise my interest, what happens if a dog needs a blood transfusion? or do they just use a plasma type substance to increase circulating blood volume.....I'll have to quiz my vet next time I speak with him.......
