February being the month of luurve I thought I would write about matters of the heart. The actual heart. Sorry if anyone got excited there!
Whenever you take your dog to the vet, your vet will listen to their heart and chest. They are checking to make sure the heart beat is strong, regular and that there are no murmurs. A heart murmur occurs when the clear drum beat of the heart (often described as ‘lub dub’) has a swooshing sound. This is caused by the blood not being pushed cleanly through the different chambers of the heart, most often escaping through leaky valves back the way it came. It is one of the commonest signs of heart disease and I am going to concentrate on them in this article.
The breed we see most often with heart murmurs is the gorgeous Cavalier King Charles Spaniel. They often develop them fairly early in life, between 4 and 6 years old is average, but don’t usually develop associated heart failure for at least a couple of years. However, they can occur in any dog and are occasionally heard in puppies (but most will grow out of them)
Heart murmurs are graded from 1-6, with 1 being the quietest and 6 being so loud the normal beating of the heart is drowned out completely. In general the louder the murmur, the worse the leaking of the valves and as the disease progresses the murmurs will get louder….
