Due to the developments in Veterinary medicine, more complex surgical procedures are done on pets. Aside from that, there is also increased use of transfusion therapy to treat different kinds of diseases making the demand increase for blood bank programs. There were no animal blood banks before, so Veterinarians had to use their own pets, their staff's pets, or even their clients' pets as blood donors.

Animal blood banks depend solely on animal blood donors. Animal blood is specific to certain specie, dogs can receive dog blood only, and similarly, cats can only receive cat blood. Moreover, dogs have blood types just like humans. Among the eleven different blood groups of dogs, the most important one is the A1/A2 system. Canines with A negative blood types are considered universal donors.

Dogs rarely have isoantibodies against other blood types, so in most cases, it is practically safe to give a dog a blood transfusion without blood typing the donor and recipient or crossmatching prior to the transfusion. Despite this, it is still recommended that all recipients be crossmatched prior to receiving a blood transfusion (especially dogs which have received a previous blood transfusion).

Cross-matching tests can either be major or minor. The donor's red blood cells are mixed with serum from the recipient in a major cross match test. It is observed if a reaction occurs. There is a possibility that the recipient's blood cells may attack donor cells and not accept them. Unless desperately needed, transfusion should not be done if there is a major cross-match incompatibility. The red cells of the recipient are compared with the donor's serum in a minor cross-match test. Only parts of the donor's blood can be given to the recipient, not the blood in its entirety, if there is a minor cross-match incompatibility.

Qualities for canine donors are: healthy, no history of metabolic or heart disease or seizures, lean body weight of greater than 50 kg, and 1-7 years of age. They should not be on any medication, except heartworm and parasite preventatives. Potential donors should have a good temperament, have been neutered and nulliparous, and have jugular veins that are easily visualized and palpated. They should also be current on vaccines. Greyhounds have been promoted as ideal blood donors because of their amenable disposition and high PCV.

After the canine's blood type is determined and is acceptable, donors are tested to make sure their blood values are high enough and no infectious disease is present before blood is drawn as with human blood donors. CBC, biochemical profile, U/A, fecal exam, von Willebrand's factor, is done as well as testing for Dirofilaria immiti, Ehrlichia canis, Babesia canis, B. gibsoni, Brucella canis (in intact or previously bred dogs), and Bartonella.

Blood donation takes more or less 30 minutes. Prior to going to the donation center, special preparations like fasting is not required, sedation of donors is not also necessary. During the blood donation, the donor is put on a table. In order to expose the skin over the vein to be punctured, there is a need to shave a small patch of hair on the neck. Then the area is cleansed with alcohol. Inserting a needle into the jugular vein, which is a large vein in the neck, collects blood. The blood that goes into the needle goes through a tube, and then it is collected into the collection bag. After the procedure, pressure is applied on the punctured site to stop any bleeding; a mild bruise may be present at the site.

To replenish fluids and nutrients, water and food are given. Right after the donation, the dog's system starts to replace the blood immediately by producing new red blood cells. As with human blood donors, it is advised that strenuous activities should be avoided for the next 24 hours after donating. A waiting period of at least two months is needed before the next blood donation. By that time, blood volume and red blood cell count is back to normal.

Dogs are compensated as soon as they have made their donation. In addition to hugs and belly rubs, they're rewarded with gifts and treats that vary from program to program. After the first donation, a dog often gets a tag, which identifies him or her as a blood donor. Edible rewards might include dog biscuits and bottled water, a jar of baby food, or a can of dog food. Some donors may even get brand new toys. At some blood banks, dogs go home wearing cool donor bandanas. In a number of programs, they also receive a large bag of dog food with each donation. This is obviously a great benefit for their owners as well.

The blood donations will then be separated into the different blood components - red blood cells, platelets and plasma to be used for both emergency and pre-planned transfusions. The red blood cells are given to recipients suffering from anemia that may be due to trauma or a treatable disease. When the animal is not producing the right amount or is losing too much protein, plasma helps increase blood volume. Platelet-rich plasma is for those recipients with decreased or dysfunctional platelets.

There are now several world animal blood banks that supply blood products to Veterinary hospitals. Most have been opened for business within the past decade. Dog owners have responded with enthusiasm to the plea for blood donations and every year, the blood bank processes roughly 2,000 units of blood donated by dogs brought in to the bank at the Veterinary hospital and to the bank's bloodmobile, which visits Veterinary clinics and kennel clubs.

Some animal blood banks depend solely on the generosity of pet owners who enroll their dogs in canine blood donor programs and take them to their scheduled appointments. Animal blood banks hold drives to encourage animal blood donations, just like what the Red Cross and other health organizations do.

If you would you like your pet to be a life-saver of other pets, and that they fit the requirements to be a volunteer donor, check out the where regional blood banks for dogs and cats or the list of Veterinary Hospitals and University Veterinary Medical Centers are located and contact the one nearest you. You can also inquire about animal blood donor programs during your next visit to the veterinarian.
