Dog Blood Types

Did you know dogs have blood types? They do! And they’re even separated into categories. Just like people, dog blood is categorized as canine universal donors or canine universal recipients.

Dogs, just like humans, have a specific blood type.

If you’re a dog owner, you may have noticed that your dog has a type of blood. It’s not the same as ours, but it’s still important to know what type of canine blood is circulating through your pup’s body. If your pet ever needs a transfusion or vaccine, donor blood that matches their type—or at least has some similar characteristics—is crucial to ensuring proper treatment.

Just as with humans, dogs have a specific blood type. There are slight differences in how these work for dogs compared to humans (for example, in some breeds it’s possible for two dogs that could be considered “brothers” by breed standards to have different blood types), but for the most part the system is similar enough to be relevant here.

The different dog blood types include DEA 1.1, 1.2, 1.3, DEA 4, DEA 3 and 5, and DEA 7

Red blood cells are the cells that carry oxygen throughout your body. The different dog blood types include DEA 1.1, 1.2, 1.3, DEA 4, DEA 3 and 5, and DEA 7.

How do you know what type of dog you have? It’s actually pretty simple! A veterinarian will take a small sample of your pooch’s blood to determine which antigens he carries in his red blood cells. If you’re wondering why we need to know this information at all—well, if it turns out your pup has an antigen that’s dangerous for people with certain conditions (like those who are allergic to dogs), then we can give you some medicine before coming into contact with him so that any symptoms will be less severe or even avoidable altogether!

When dogs need blood transfusions, it’s important that the donor blood is compatible with the receiver.

You may be wondering: How do you know if a dog has a particular blood type?

The answer is simple. If you’re willing to get your hands dirty, there are plenty of ways to test a dog’s blood type. You can draw some of the animal’s blood and send it off to a laboratory for testing, or even just use an eyedropper! There are also home kits available online that allow owners to test their pets’ blood types at home.

However, these tests aren’t foolproof—and sometimes they yield inaccurate results. For example, some dogs might have “universal” blood types (the same as humans), while others might not have any universal match with humans at all. In other words: not every donor will be compatible with every recipient.


It’s important to understand the importance of blood donation programs. Blood donation can save lives, money and time for people who need it. It also saves stress for those who donate their blood because it makes them feel good about helping others out.

That’s all you really need to know in order to keep your dog happy and healthy. While some breeds have a greater risk of developing conditions that require transfusions, they’re still less common than other conditions such as cancer. So if your dog has some type of condition that requires blood transfusions, then it’s good for them to know what type they are before anything happens so they can be prepared!
