Heart disease in dogs

| August 25, 2017 | Reply

The common heart diseases suffered by dogs often lead to heart failure. Dogs will generally suffer what is called Congestive Heart Failure (CHF), a relatively slow worsening of symptoms. However, there have been major advances in veterinary medicine over the years and the outlook for a dog with heart failure is often not as gloomy as it once was.
Disease usually starts to affect one part of the heart and goes on to damage other parts.

The vast majority of heart disease cases in dogs are considered acquired heart disease. Typically the result of normal wear and tear, they can also be caused by injury or infection. They’re most often seen in middle-aged and older dogs. Some of the most common types of acquired heart disease are:

– Chronic valvular disease, when the valves of the heart weaken with age and begin to leak.

– Myocardial disease, when the heart muscle weakens, causing it to enlarge.

– Arrhythmias, when there’s a problem with the body’s electrical system, which tells the heart how to beat.

– Pericardial disease, when the protective sac that surrounds the heart fills with fluid, preventing normal beating of the heart.

Congenital defects, the other cause of heart disease, are comparatively rare problems a dog is born with. You’ve probably heard of a heart murmur, which is caused by a defect in the heart that disrupts blood flow, creating a whooshing sound that can be heard through a stethoscope. Heart murmurs aren’t necessarily anything to worry about. Among puppies, the condition usually clears up on its own by four to six months of age.

Other congenital defects often involve the improper development of a specific part of the heart, or a small hole in one of the chambers. There are many different types, but the result’s the same: the heart can’t function properly. Such defects can limit a dog’s lifespan and make him more susceptible to other problems. Very mild cases, however, may have little effect.
