Blood Types and Donation of Blood in Dogs

Dog Health

Just like in humans, in dogs with excessive blood loss or blood disease, blood can be taken from a healthy dog ​​and given to a sick dog. However, the canine blood group is different and more complex than that of humans. The fact that dogs have more blood types also makes matching these groups more complicated.

Dogs Blood Types

Just like humans, dogs have different blood types. “Do dogs have blood types?” The more important question is “How many blood types do dogs have?” is the question. More than a dozen canine blood has been discovered to date, and it is thought that this number will increase with new research.

The blood group in dogs has complex genetic patterns. The blood type is inherited from the dog’s ancestors. Each group inherits independently. This results in a dog being able to have any combination of more than 12 blood types. The answer to the question “How many blood types do dogs have?” becomes complicated at this point. The diversity of blood types in dogs provides a correlation with the geographical location of the breed and the breed itself. The most common canine blood types vary by geographic location and breed.

Although there are many blood group and potential blood group combinations in dogs, “dog erythrocyte antigen” for short, CEA 1 is the most important from a medical point of view. Some dogs are DEA1 negative. In positive dogs, there are two different forms, KEA 1.1 and KEA 1.2.

Which is the most ideal blood group for blood donation?

When blood types are quite complex, “What blood type is dog blood?” It is also difficult to answer such questions. The most ideal blood group for blood donation in dogs is the blood group that is KEA 1 negative. Because this blood can be given to dogs with KEA 1 negative, as well as dogs with blood group KEA 1.1 or KEA 1.2. However, this does not make KEA 1 negative blood group a general donor. Giving a KEA 1 negative blood group to a dog that is positive for another blood type can cause health problems.

“How to give blood to dogs?” The question is also one of the most frequently asked questions. Extra tests are needed to get right through the process of giving blood to dogs. Cross match testing is done to ensure that the blood type of the donor dog will not cause a serious immune system problem in the recipient dog. This test looks at the exact compatibility of the blood of the donor dog with the recipient dog. Once the KEA has identified the 1 blood group type and performed the cross match test, the veterinarian can successfully identify the required blood group for the dog.

What to Look for for Blood Donation in Dogs?

In very urgent situations any dog ​​can give blood, but some dogs are better at it. Veterinarians primarily prefer KEA 1 negative blood type, but some other characteristics of the dogs that will donate blood are also taken into consideration. The dog to donate blood should be over 22 kilos and have a healthy weight for its size. Large breed dogs can donate higher volumes of blood than small breed dogs. Apart from this, the dog must be fully vaccinated, no heart murmur, no medication, no infection, no parasites in his body, no blood diseases. The blood donation process takes about 10-15 minutes. For this reason, blood sampling is generally preferred from dogs that can remain calm.

Which Diseases Cause Blood Needs?

“Why is blood drawn from dogs?” The answer to the question is actually the same as the process in humans. In order to give blood to the sick dog, blood is taken from healthy dogs. Dogs with excessive blood loss after trauma or during surgery may require blood. Some diseases, such as von Willebrand’s disease, can cause severe blood loss by causing bleeding. These diseases can only be treated with blood transfusions.

In diseases that break down blood cells, blood transfusion is required for the dog to feel better and be healthy. For a dog with any of these conditions, a blood transfusion is lifesaving.

How Does Blood Transfusion Happen in Dogs?

The blood transfusion process is again very similar to that in humans. Another dog can give blood for the sick dog, or blood can be taken from the blood bank. “How to give blood to dogs?” The answer to the question is “How to draw blood from dogs?” It is as complex as the answer to the question. Before the transplant, both dogs are tested for cross match. First, a blood sample is taken from the dog that will receive blood and the immune system response is checked using a blood sample from the donor dog. Then the opposite is done. This test is very important because when a KEA 1 negative dog is given KEA 1 positive blood, the immune system attacks the new blood cells, reducing the effectiveness of the blood. In addition, an allergic reaction occurs in the body.

When blood is obtained from another dog or blood bank, it is kept in a special serum that prevents clotting. When the transfer is made, the blood is connected to the serum line with a special filter. Blood transfer is given directly into the vein through the serum catheter. The amount of blood transfer to be performed varies according to the size of the dog and the amount of blood lost. This process is closely monitored to make sure the dog is not having an allergic reaction.

In many health problems, a one-time transplant is enough for the dog to recover. However, in some diseases, such as ongoing blood loss or destruction of blood cells, repeated transplants may be needed. The need for blood transfusions in dogs occurs very rarely, and when such a need arises, the transfusion is life-saving.
