What is a heart murmur in dogs?
A heart murmur in dogs is an abnormal sound that is produced by the blood as it circulates through the heart. It is usually heard by a veterinarian when they listen to the dog’s heart with a stethoscope. Heart murmurs are not a disease in themselves, but rather a symptom of an underlying condition that affects the heart’s structure or function. In some cases, heart murmurs may be harmless, but in others, they can be a sign of a serious condition that requires immediate treatment.
How is a heart murmur graded in dogs?
Heart murmurs in dogs are graded on a scale of 1 to 6, with 1 being the mildest and 6 being the most severe. The grading system is based on the intensity of the murmur, as well as the location and timing of the sound. A grade 1 heart murmur is barely audible and may not be detectable in all parts of the heart, while a grade 6 heart murmur is very loud and can be heard even without a stethoscope.
What does a grade 4 heart murmur indicate?
