Dilated cardiomyopathy and large dogs

Dilated cardiomyopathy is a disease that affects the heart and is seen most often in large and giant breed dogs. In this condition, the heart becomes enlarged and the walls of the heart become very thin, making the heart very weak and unable to pump blood effectively.

The highest incidence of this disease is found in Boxers, Doberman Pinschers, Springer Spaniels, German Shepherds, and Great Danes. Dogs are typically two to five years old when they first experience symptoms and are usually male dogs.

The cause of this disease is unknown. The most common symptoms include weight loss, lethargic dogs, whole very easily, rapid breathing, frequent cough and cough that is especially common at night, in severe cases dogs will have a swollen abdomen because fluid will accumulate there.

Diagnosis is usually made by X-ray, ultrasound, or ECG. Treatment is usually aimed at trying to improve the force of contraction of the heart muscle and prevent any arrhythmias. Diuretics are also commonly given to reduce the amount of fluid that builds up in the lungs and abdomen.

The prognosis of this disease is usually reserved and also depends on the stage in which the veterinarian diagnosed the disease.

However, if you have excellent control with medications, some dogs can live another year or even longer. Deaths normally occur from sudden cardiac arrhythmias, so they need to be properly managed. If you notice any sudden changes in your dog’s activity levels, you should contact your veterinarian immediately.
