FACTS ABOUT HEART MURMURS & VALVE DISORDERS
Includes Birthday Treat Recipe – scroll to bottom
Today my little Valentine celebrates her twelfth birthday! Reese is a puppy mill rescue who has, had a heart condition for as long as we’ve had her.
Although it is scary to learn that your dog has a murmur or any other condition, we hope to share some information that proves that many dogs carry on without ‘missing a beat.’ Reese is one such dog.
The murmur itself is not a disease; it is a specific sound detected when listening to the heart with a stethoscope. It is the sound of extra vibrations of the heart produced as a result of a disturbance in the blood flow. The blood is flowing faster than normal within the heart itself or in one of the two major arteries leaving the heart. In Reese’s case, it sounds like a faint woooshhh, wooshhh, wooshhh sound.
Heart murmurs in dogs can develop at any stage of their life. The implication, however, can be very different depending on the age of the dog when the murmur is first detected.
Often, the murmurs are graded based on a variety of characteristics, including their timing and volume. A grade one murmur, for example, is subtle, and a grade six murmur is loud. Reese’s murmur is currently a grade two. They can change over time, so it is important for your vet to monitor your companion.
Systolic murmurs occur when the heart muscle contracts; diastolic murmurs occur between beats when the heart muscle relaxes, and continuous
to-and-fro murmurs occur throughout all or most of the cardiac cycle.
Grading Scale for Heart Murmurs in Dogs (Pet MD)
Grade 1—barely audible
Grade 2—soft, but easily heard with a stethoscope
Grade 3—intermediate loudness; most murmurs which are related to the mechanics of blood circulation are at least grade three
Grade 4—loud murmur that radiates widely, often including opposite side of chest
Grade 5—very loud, audible with stethoscope barely touching the chest; the vibration is also strong enough to be felt through the animal’s chest wall
Grade 6—very loud, audible with stethoscope barely touching the chest; the vibration is also strong enough to be felt through the animal’s chest wall
What causes murmurs:
Heart defects and infectious, inflammatory or other disease processes are the cause of murmurs. Endocarditis (mitral valve disease) is an inflammatory change of the tissues lining the heart chambers and valves and is a common cause of canine cardiac disease. Stenosis is a narrowing or constriction of an artery or vein that causes increased turbulence of blood flow in the affected area. Dysplasia is an abnormality of development, such as some alteration in size, shape, organization or structure (often occurring at birth).
Other causes of heart murmurs include damage to the muscle. For example, a hole or tear in the interior wall separating the heart chambers. At birth, this could appear as the failure of an important blood passageway closing in the fetal heart. Other causes may include Cardiomyopathy (a primary disease of the heart muscle), Infection due to heartworm disease, Hyperthyroidism, and anemia.
Signs of a Heart Murmur:
Dogs and cats with heart murmurs may show no signs and, as was the case with Reese, the murmur was first detected during a routine examination by her veterinarian.
Depending on the grade, and configuration and association with structural heart disease, your dog’s initial symptoms may only be apparent to your vet. Later on, however, you may notice some coughing, exercise intolerance, or weakness, rapid breathing, and possibly fainting. Our vet advised us to keep an eye on the colour of Reese’s tongue. If it starts to turn even slightly purple, we give her a time out from fetch.
Treatment:
Many murmurs never require medical attention, even if they are pronounced. Causes of minor murmurs are often managed with exercise (may need to be reduced), and diet. Medication or surgery may be necessary if symptoms worsen or for severe heart conditions.
Medication may be required to reduce the burden on the heart and improve function. Medications may also be prescribed to help control blood pressure and fluid retention.
Heart murmurs can occur in both dogs and cats.
Ten years after we rescued her, Reese still wants to play fetch 24/7 and requires no medication for her condition!

A very informative post about heart murmurs. I’ve know humans that are affected by them, but honestly didn’t know much about heart murmurs in detail. I’m happy to hear that Reese has not been too affected by this and is doing well at 12 years of age!
Happy birthday Reese!

Happy Happy 12th Reese!!! My former cat was diagnosed with a heart murmur when he was about 12…….he lived 18 wonderful years!
Rachel says
Very valuable info on heart murmurs – thank you! I’m glad that Reese is doing well all these years later. And those treats look delicious!
Amy Shojai, CABC says
What a great recap of this condition, thanks for sharing! Important to keep track of the issue and glad Reese is doing wll.
Hindy Pearson says
Thanks for such a thorough and informative post. It’s true, the first time you hear the words “heart murmur” you start to panic. I learned awhile ago not to do that because several of my dogs and cats have had it, and they lived (and some are still living) happy, pretty healthy and love filled lives.

Happy birthday. I have a cavalier, so it’s always about being heart-healthy and seeing the cardiologist every year to keep an eye on his heart.

I appreciate the informative article on heart murmur. I actually grew up with a heart murmur and then my first cat had one. Hers was controllable until her last year, when she also developed kidney issues.
Happy birthday to your sweet buddy! She seems full of life and happy. Thank for having many years ago given a home to a puppy mill rescue.
Sadie says
Thank you, Allison, for sharing your experiences and for the Birthday wishes!
Beth says

Dash Kitten Crew says
I know when a person gets a heart murmur they worry – so it must be a worry for pet owners too. People nowadays come online for exactly the informatin you give here, sensible and encouraging. I think people will find it reassuring that there is not an instant and large amount of medication to be given too (the cost!).
Thank you for a really useful post.

Happy 12th birthday! That’s honestly amazing – no medication! I remember learning about the grading scale as a tech in school. This is a super important topic as it’s very confusing to owners and knowing the signs and causes is half the battle. The color of the tongue is a great tip for owners. Thank you for sharing and happy 12th — sweet senior!

Very much like humans – a great post about heart murmurs. When we’ve adopted seniors we learned a lot about heart murmurs – and once you understand and manage accordingly, it’s quite easy. Reese is a lucky pup – Happy Birthday!
