Dr. Rebecca Malakoff is a board-certified small animal cardiology specialist in Massachusetts. She is based out of Westwood, MA, and is available to serve general practice and emergency animal hospitals throughout the greater Boston metro area.


Dr. Malakoff is a board-certified veterinary cardiologist and Massachusetts native. After graduating from North Carolina State University College of Veterinary Medicine in 2000, she completed both a rotating small animal internship and cardiology residency at Angell Animal Medical Center. Dr. Malakoff has 20 years of experience in private practice in the Boston area, diagnosing and managing a myriad of cardiac cases. She served as residency director for the Angell Animal Medical Center cardiology program, as a volunteer on the ACVIM Residency Training Committee in cardiology, and has authored and co-authored numerous text book chapters and peer-reviewed journal articles.

Dr. Malakoff enjoys being able to provide non-invasive diagnosis of cardiac disease via echocardiography. She is particularly interested in helping clients by providing pragmatic treatment options, reducing stress for both the human caretakers and pet patients. She lives with her husband, two sons, and two cats in Westwood, MA.

    What is a board-certified veterinary cardiologist?

    A veterinary cardiologist is a specialist that has advanced training in the heart and circulatory system. To become a board certified veterinary cardiologist a veterinarian usually completes a one year internship followed by extensive specialized training in an approved residency training program (usually 3-5 years).

    Board certified veterinary cardiologists focus on diagnosing and treating disease of the heart and lungs, which include Congestive heart failure (CHF), Heart muscle disease (Dilated cardiomyopathy or hypertrophic cardiomyopathy), age-related changes to the valves of the heart (Degenerative mitral valve disease), coughing and other breathing problems, congenital (present at birth) heart defects, cardiac arrhythmias (problems with the rate and/or rhythm of your animal’s heart), diseases of the pericardium (sac surrounding the heart), cardiac tumors, high blood pressure (hypertension), and pulmonary hypertension (high blood pressure in the lungs).

    Veterinary cardiology specialists will perform a complete and thorough physical examination on your animal, and based on these initial findings, additional tests will be discussed. Depending on your animal’s condition, diagnostic testing or treatments may include echocardiography (sonogram) – non-invasive ultrasound imaging of the heart, electrocardiography (ECG) – non-invasive electrical reading of the heart’s rhythm, blood pressure evaluation, Holter monitor – 24 hour ECG performed at home, or radiography (x-rays) of the chest and lungs.
