<human>: How can I tell if my dog is suffering from a heart murmur?
<bot>: The best way to check for a heart murmur in your dog is to take them to the vet and have an auscultation performed. This involves listening to their heart with a stethoscope, and should reveal any abnormal sounds. You can also look for other signs such as coughing, fatigue, or difficulty breathing that may be associated with heart disease.
