What is a Pet Heart Murmur?

A pet heart murmur is an abnormal sound heard when listening to the heart. It's a common condition that can affect both dogs and cats. According to veterinarian Dr. Jane Smith, 'A heart murmur is not a disease itself, but rather a symptom of an underlying condition.'

There are several causes of a pet heart murmur, including structural heart problems, extracardiac issues, and innocent murmurs. Structural heart problems can include conditions such as mitral valve disease, while extracardiac issues can include anemia or hyperthyroidism. Innocent murmurs, also known as physiologic murmurs, are common in puppies and kittens and often resolve on their own.

Symptoms of a Pet Heart Murmur

Symptoms of a pet heart murmur vary depending on the underlying cause. Common symptoms include coughing, difficulty breathing, lethargy, and loss of appetite. In some cases, pets may not exhibit any symptoms at all.

Treatment Options for a Pet Heart Murmur
