Thanks for using Petco Pet Education Center, formerly Petcoach! Yes, that would be considered an emergency. The main reason is that dogs with heart murmurs and heart disease can develop congestive heart failure which is a medical emergency that would warrant evaluation as soon as possible for Maya. The veterinarian would be able to check for this possibility and treat accordingly. Usually if congestive heart failure is confirmed, she may need oxygen therapy, diuretic medications and medications to make her heart work better. Good luck! Wishing Maya the best!
