What causes a heart murmur in an older dog?
A common problem in older dogs is a myxomatous mitral valve. This is just a fancy way of saying the valve becomes stiff and thickened. When the valve affected is the mitral valve, the condition is known as mitral valve disease.
Where do you hear a murmur in a dog?
In the case of MMVD, the murmur occurs between the normal “lub” and “dub” heart sounds. Murmurs can be heard most clearly at a particular point on the left side of the dog’s chest.
What does a Veterinarian grade a heart murmur?
Your veterinarian will grade the heart murmur out of 6, with 6/6 being the loudest murmur. In some instances, the louder the murmur, the more significant the abnormality within the heart. Soft heart murmurs (grade 1/6 to 2-3/6) can occur in young animals and are of no consequence to them. These types of murmurs are called “innocent” murmurs.
What does it mean when your dog’s mitral valve leaks?
We refer to this disease as chronic valve disease, endocardiosis or degenerative mitral valve disease. Mild chronic valve disease that leads to small leaks across the mitral valve usually does not create an problem for a dog. The disease is slowly progressive in most cases and the leak will continue to worsen over months to years.

Can a stethoscope detect a heart murmur in dogs?
A heart murmur is an extra heart vibration which results in an abnormal sound caused when there is a disturbance in the blood flow. The detectable noise is one that is distinguishable from a regular heartbeat and can be heard by a doctor with the use of a stethoscope. If your dog has a murmur, it is not an immediate cause for panic.
Can a veterinarian hear a Grade II heart murmur?
Grade II murmurs are soft, but your veterinarian can hear them with the help of a stethoscope. Grade III murmurs have a loudness that falls in the middle of grades II and IV. Most murmurs that cause serious problems are at least a grade III. Grade IV murmurs are loud and can be heard on either side of the chest.
Where does the blood go in a heart murmur?
The atrium contracts pushing the blood into a larger chamber, the left ventricle. The latter then contracts to push blood around the body. A valve (the mitral valve) is like a one-way swing door, policing the path from the left atrium to the ventricle.
