Canine Cardiology

By: Michael Lamping, DVM

            Pacemakers, echocardiograms, cardiovascular bypass, open-heart surgery, valve repair, correction of congenital heart defects sounds like a list of tools and techniques used in the cardiology department of a human hospital.  Actually the above medical advancements are being performed by veterinarians who specialize in canine cardiology.  Unfortunately dogs suffer from some of the same heart ailments as we do, but many things can now be done to help dogs with heart problems.

            As they age, dogs may acquire heart disease such as chronic valvular disease and may show the symptoms of congestive heart failure.  Acquired valve disease particularly affects small breed dogs over 9 years of age.  Due to a thickening of the valves, blood flow is no longer restricted to one direction, and blood accumulates in the veins.  Common small breeds known to have pre-disposition to this condition are cocker spaniels, dachshunds, Boston terriers, Chihuahuas, miniature and toy poodles, Cavalier King Charles spaniels, and miniature schnauzers.

            Owners could see symptoms of cough, difficulty breathing, weakness, weight loss, and possibly an enlarged abdomen.  Veterinarians listen to the heart and the lungs, feel the pulse rate and quality, and assess the gum color as part of the physical exam.  At Murphy Road Animal Hospital, we are also able to evaluate chest radiographs, electrocardiograms (EKG), and blood pressure.  We can even arrange for an echocardiogram, which is the use of ultrasound to evaluate the heart.  Most dogs respond well to medications and do not undergo surgery.

            The heart is as a vital organ whose role in providing quality to life cannot be underestimated.  I recommend an annual heart exam for your pet, especially senior pets and those most at risk of heart disease.
