 Jack the cheeky eight year old Cavalier King Charles Spaniel came in for his yearly vaccination and routine health check. During the examination, a heart murmur was detected. After questioning his owners, there was some concern that he may have been a bit slower on his walks lately too.
A heart murmur is simply an abnormal sound produced when blood is pumped through the heart. It can be caused by a diseased heart valve or other abnormality, but can also occur when blood flows very fast across normal structures (especially if a pet is excited).
X-rays of Jack’s heart revealed his heart was enlarged but there was no congestion (blood pooling) in his lungs. His owners opted for a more in-depth work up which included an ultrasound of his heart. This looked at all the structures of the heart more closely, and determined that the underlying cause of the heart murmur was mitral valve disease.
This disease is common in small breed dogs and is caused by a ‘wearing out’ of the mitral valve, which separates the left atrium and left ventricle. It can lead to congestive heart failure and can be fatal.
Jack was started on a medication that helps to improve the pumping mechanism of his heart. This will slow the progression of heart failure, and it reduces the amount of work the heart has to do over time. Studies have shown that this medication can improve a dog’s longevity and quality of life if started early enough.
It is likely that early detection means that Jack will live a longer and healthier life. He also has more energy on his walks and is one happy little pooch!

Absolutely! Heart disease is not uncommon in dogs and cats, and knowing what to look out for is important as it can really make a difference to your pet’s life. Our feline friends are particularly good at hiding signs of heart disease, but the condition can sneak up in all pets. To make things more complicated, heart disease may not always present with obvious clinical signs. This is just another reason why a check up with us at least once a year is vital (we will always listen to your pet’s heart and lungs).
Grain free diets have become more popular over the last few years, as people inaccurately assume these boutique diets are better for their pets. But there’s more to the story...
We continue to feel devastated for all involved in the bushfire crisis. The effects of this disaster have rocked us all, and we are deeply saddened to see the impact it has had on our wildlife and livestock, as well as the communities and beautiful bushland that makes Australia so unique. It will take many years to rebuild communities and restore crucial habitat for our beautiful fauna. We would like to remind you of ways you can help our wildlife in particular:
