Blood Donor Program

Healthy dogs and cats can help animals in need by becoming blood donors at the Animal Emergency Clinic of Mid-Maine (AECM). Whole blood is often needed for critically ill and injured animals suffering from serious trauma due to motor vehicle accidents, as well as for major surgeries and anemia. For more information, contact AECM at (207) 777-1110 or email us.

How It Is Done

  • Some dogs and all cats are lightly sedated for the donation procedure, and a small area around the pet's neck is shaved and cleaned.
  • Roughly 16 ounces of blood is drawn from dogs. For cats, less than 2 ounces is drawn.
  • Your pet will be monitored by AECM staff and should remain quiet for the rest of the day.

Guidelines for Donor Dogs

  • Must weigh 50 pounds or more.
  • Age: 1-8 years (1 to 5 for giant breeds).
  • Must be friendly and have no major medical problems.
  • Must be current on vaccinations (must show proof).
  • Must be on heartworm preventative medication.
  • Must never have tested positive for Lyme disease.
  • Must never have received a blood transfusion and no history of pregnancy.
  • We typically use universal donors, but do keep a list of positive donors if needed.

  • Minimum weight: 9 pounds.
  • Age: 1-8 years old.
  • Friendly and no major medical problems.
