Is it common for puppies to have heart murmurs? Heart Murmurs Often Go Away By Six Months of Age. Although the occurrence is rare, some puppies are born with heart conditions that should be detected and treated as soon as possible to ensure that they lead a healthy life.
How long can a puppy live with a heart murmur? Many dogs live a long time after being diagnosed with a heart murmur, and some can even live years after being diagnosed with heart failure.
Do puppies usually grow out of heart murmurs? A heart murmur occurs when there is turbulent blood flow within the heart. Some murmurs, especially those found in young puppies, can be ‘innocent’ or ‘physiologic’ and will have no negative effects on your dog’s health. Young puppies with innocent heart murmurs will usually outgrow them by about 5 months.
Should I worry if my dog has a heart murmur? If your dog has a heart murmur and you see coughing, congestion, change in breath sounds or rapid breathing, exercise intolerance, weakness or “fainting,” gray or blue gums, abdominal distention, or lethargy, you should most certainly seek medical attention.
