You hear stories about dogs with big hearts, lovely kind natures and a loyalty to their owners which is second to none. However, a dogs' heart is one of their vital organs and it needs to be kept in tip top condition at all times.

    Some breeds are prone to suffering from heart conditions and others are born with a heart murmur or other heart problem which is called congenital because the condition is inherited from on or other of the parents.

    Congenital murmurs usually first appear when a puppy is still growing in their mother's uterus or very soon after they are born. The condition is as a result of defects in their development. Congenital heart murmurs need to be taken very seriously as they can cause dogs to suffer some very severe symptoms which includes sudden death, a condition caused by aortic stenosis.

    The heart is the body's pump and its role is to continuously push blood around the body in all living creatures. There are two sides to a heart, namely the right and the left side. It's the left side that receives oxygenated blood from a dog's lungs and then pumps it out to the body and brain.

    De-oxygenated blood goes into the right side of the heart and is then pumped into the lungs to be oxygenated. The right side of the heart is considered as being the low pressure side of things due to the fact the blood entering into it only needs to be pumped a short distance until it arrives back in the heart.

    The left hand side however, has a much bigger task and is thought of as the high pressure side, which means the left side is always stronger and bigger than the right. Within the heart, there are four chambers called the left and right atria and the left and right ventricles. Each atrium has valves separating them, with the ventricles having them at each exit point that leads to the how to change appearance in gta 5 online. These valves play a crucial role in preventing blood from flowing back to the heart in the wrong direction each time that it pumps any blood through it.

    But when the heart is diseased this smooth flow is interrupted and disturbed making it sound more turbulent, often you can barely hear a heartbeat at all. Vets listen to a dogs' heart in different places because a murmur can vary depending what logo is red and white just what type of heart disease is causing the condition. It is more common for a dog to suffer from an acquired heart disorder which can often be as a result of a chronic disease that affected the heart's valves.

    However, the condition could also be a result of a diseased heart muscle with some dogs suffering from both conditions at the same time. The most common being a thickening of the valves called Endocardiosis. The condition may start early in a dogs' life with just mild signs being present.

    However, the condition gets progressively worse as dogs get older. The changes may be slow which often means the heart is able to cope with the changes by compensating for them. Nobody actually knows what is a heart murmur in dogs changes in a dog's heart valves happen, but small dogs appear to be more predisposed to suffering from the condition than larger canines.

    It's the left side of a dogs' heart which is usually damaged but with this said, any of the hearts' valves can be affected. Another reason a dog may suffer valve problems can be put down to when blood borne infections settle in the lining of the heart causing it to become inflamed.

    The infection could be a result of another septic infection found somewhere else on their bodies and if it reaches the heart, it usually affects the left side causing a murmur. When it comes to heart murmurs, there are many reasons why a dog may suffer from the condition.

    Causes of Heart Murmur In Dogs

    Apr 18,  · A: A heart murmur is an audible sound that is produced by the heart when there is disruption to the normal, orderly flow of blood through the four chambers. While there can be a variety of causes for the murmur, the most common cause in dogs is from a valve leaking. Dilated cardiomyopathy (DCM) is a serious and often fatal condition in medium to larger breed dogs. Signs may be sudden or progressive in onset. Some signs include rapid breathing, increased effort with breathing, restless sleeping, coughing or gagging, among others. Early and proper diagnosis is key followed by treatment to give the best quality of life. A heart murmur can present as a number of different sounds, frequently as a “rumble” or burble, and are differentiated according to which stroke of the heart they are associated with (e.g. systole (filling stroke) and diastole (ejection stroke), or whether they are continuous.

    Heart murmurs in dogs are extra vibrations or sounds in the heart that come from abnormal blood flow. A heart murmur is not a condition on its own, but rather a symptom of an underlying condition. There is no direct treatment for heart murmurs in dogs, but the causes can often be treated, which may reduce the vibrations in the heart.

    Your veterinarian will find the cause of the heart murmur and then form a treatment plan. Vets give heart murmurs in dogs a grade of I to VI. Grade I heart murmurs are barely audible, while grade VI murmurs can often be heard even without a stethoscope. Vets also classify them based on the location of strongest intensity and the pattern that the vibrations follow. These classifications, along with any other symptoms dogs have, help further narrow down the cause of the heart murmur, allowing vets to form a proper diagnosis and treatment plan.

    You must get to your vet if you see concerning symptoms in your dog. Not all heart murmurs in dogs result in apparent symptoms. Some are completely benign and disappear with time. However, many others are associated with heart disease. If you see the signs of heart disease accompanied by a heart murmur, then you must consult your vet immediately. Sometimes heart murmurs are benign, and dogs may just grow out of them. Other times, they can result from and indicate more serious medical conditions.

    They occur when puppies, especially large breeds, grow quickly, and generally they disappear on their own after a few months. Heart murmurs in dogs can be also caused by a variety of medical conditions. They can be congenital present at birth , result from heart defects, or appear with infections, inflammation, or other diseases. Here are a few of the conditions that can cause a heart murmur :. But vets will address the underlying causes.

    Treatment can vary greatly depending on the cause and severity of the condition. Conditions that cause heart murmurs must be addressed by a veterinarian. In the case of heart defects, dogs may need surgery to correct the condition.

    Tumors may require chemotherapy. Vets may treat other issues with medication. Your vet will develop a proper treatment plan after forming a diagnosis. Has your dog ever suffered from a heart murmur? What was the cause? Let us know in the comments below! Picture Credit: Getty Images.
