Blood Bank


The BluePearl Blood Bank is dedicated to providing a safe and plentiful blood supply to animals in need. Our goal is to ensure that all cats and dogs who present to emergency facilities or family veterinary practices across the region have access to life-saving blood products.

Prospective blood donors schedule an appointment for a brief veterinary exam at BluePearl Veterinary Partners where a small amount of blood is drawn for typing and testing.

The blood sample is tested for infectious diseases in accordance with the American College of Veterinary Internal Medicine (ACVIM) consensus statement guidelines for blood donors (at no cost to the owner).

If blood-screening results show your pet is able to donate, prospective donors return for their first donation and additional blood screening.

Once approved, the new BluePearl Blood Bank donor will be asked to commit to donating once every two to three months for three years.

At each donation, a brief exam is performed prior to donating.

For dogs, the entire donation process takes approximately 30 minutes. (This includes time for the exam and for the donor to enjoy their treats and affection from the staff.)

Cats require a mild anesthetic, so their donation is a drop-off appointment. The donation takes about four hours, and you will be notified when your pet is available to be picked-up.

Do dogs and cats have different blood types like people?

Dogs have a numbered blood typing system called Dog Erythrocyte Antigen (DEA) system. DEA 1.1 is the main blood type and dogs can be positive or negative. DEA 1.1 Negative is a universal blood type and is safe to be given to any other dog. Cats have three different blood types: A, B, and AB. Type A is the most common with type B found in about 5% of the population. There is no universal blood type for cats.

Is blood donation risky or painful to my pet?

The donation process is quick and painless. The most common potential side effect is bruising at the site of collection, but that goes away within two to three days. The amount of blood taken is not enough to alter your pet’s health. The body replaces red cells taken naturally. Dogs and cats can safely donate every six weeks.

How much blood is drawn at the time of donation?

Each dog donates approximately 450 mls (one pint or two cups) at each donation. Each cat donates 53mls (two ounces) at each donation. For cats, fluids lost during the donation is replaced by administering subcutaneous fluids.

Will my pet need to be sedated or restrained to give blood?

The majority of dogs are able to sit still for the donation with no problem. On rare occasions, an excitable dog may need a light sedation to calm them during their donation. On the other hand, cats do better with a short-acting anesthetic. They are carefully monitored and only asleep during the 10 to 25 minutes needed for the donation process.

Why do dogs and cats need blood transfusions?

Many situations require the use of blood products including trauma, ingestion of poisons or surgical complications. Some animals also have immune problems that can cause them to have low red blood cells or platelets.

What kind of commitment is required?

Due to the high cost of screening prospective donors, your pet is asked to commit to 12 donations. (Donating once every two to three months for three years.)
