In this way, a dog with cardiac pathology who is overweight needs a low-calorie diet. In the opposite case, it would be found that he suffers from chronic weight loss (cachexia), which is also characterized by muscular atrophy, fatigue and weakness. In this case, the animal needs a diet high in calories.

2. Avoid the obesity of the dog with cardiac pathologies

Age is a common risk factor for them to develop heart conditions. In general, all older dogs end up having heart failure. "85% of greater they suffer it, "says Juan Antonio Aguado, veterinarian.

Certain dog breeds, such as large ones (mastiff), have a greater tendency to suffer certain heart problems. Large dogs age at a faster rate than small dogs, and with seven years they can have alterations in the functioning of their heart, which can be weak. However, the small dogs They may also have other heart conditions, such as endocardiosis or degeneration of the heart valves.

5. Moderate exercise for can with cardiac pathologies

The fact that a dog has a sick heart does not imply that he needs a sedentary life. Quite the opposite. In these cases, moderate exercise is a trick to keep the canine heart in shape.

However, "the dog that suffers from the heart must perform an amount of physical activity according to its ability," explains Aguado. So if the dog is tired during the walk, it is advisable to return home to rest, and not insist on continuing physical activity.

Symptoms of heart failure in dogs

Congestive heart failure It is a pathology that dogs are at risk of suffering as they age, since the walls of his heart are weakening and he does not have the necessary strength to pump enough blood to the whole organism, causing a lack of oxygen. But nevertheless, This does not mean that it happens only to elderly dogs, in fact it can happen to any dog ​​at any time.

However, in the case of heart failure, it not only occurs due to old age, other times it is due to congenital problems or to different heart failures. Other causes of heart failure in dogs are:

  • Tumors
  • Heartworm
  • Endocarditis and other heart valve problems
  • Heart wall problems
  • Liquid retained around the heart
  • High blood pressure

Treatment and care of a dog with heart failure

The treatment of heart failure in dogs It depends on your cause. For example, if it is a consequence of any pathology, the appropriate treatment will be put in place to cure it and with it the insufficiency will improve or disappear, If it is a genetic problem, surgery is likely to be necessary. In many cases, when the cause is old age, this pathology has no solution and the treatment is based on reducing symptoms to improve their quality of life as much as possible.

What is heart failure?

Heart failure is the medical terminology used to name various disorders characterized by weakening of the heart. There is talk of inadequacy when an organ fails to fully exercise its functions due to some anomaly. In the case of the heart the insufficiency is in not offering the necessary amount of blood to the organism.

To try to preserve the organic balance, the body activates certain mechanisms to guarantee the oxygenation of organs and tissues, but the intensification of cardiac damage usually overwhelms these compensatory measures. Heart failure affects humans, dogs and cats very similarly.

If we analyze the data at national or international level, the samples are evident. The American Heart Association has found that About six million people live with heart failure in the United States alone.

Causes of heart failure in dogs

The most common cause of heart failure in dogs is severe dilated cardiomyopathy, that is, a condition that weakens the walls of the heart. In females, pregnancy is taken as a possible cause of degeneration of the walls and heart valves.

But the pathology is also associated with the following factors:

  • Accumulation of fluid in the pericardial sac.
  • Heart valve deficiency.
  • Canine Dirofilariasis (‘heartworm pathology’).
  • Heart rhythm disturbance
  • Arterial hypertension.
  • Infection of the heart valves (endocarditis).
  • Cardiac neoplasia

Development of heart failure in dogs

Heart failures can affect the right, left or both sides of the heart, and the point of origin determines the characteristics and evolution of the disease.

On the one hand, it should be noted that when the insufficiency is focused on the right side, the unpumped blood remains accumulated in the abdomen.

For other, the original anomalies on the left side of the vital organ cause excess fluid retention in the lung. In both cases, the accumulation is very dangerous due to the risk of causing congestion or bleeding.

Further, heart failure in dogs can cause gradual enlargement of the left ventricle. This phenomenon is commonly known as ‘enlarged heart’ and, in the most severe cases, The heart becomes so fragile that it no longer manages to pump blood into the body.

Diagnosis of heart failure in dogs

When recognizing any of the above symptoms, it is essential to go quickly to the veterinarian. The professional will proceed appropriately to perform the necessary tests.

The diagnosis of congestive heart failure usually includes the following tests, to find out the cause of the weakening:

  • Blood: to detect the ‘heartworms’.
  • Blood pressure measurement and stress test.
  • Torax X ray.
  • ECG or electrocardiogram.
  • Echocardiogram: to verify the anatomy and functioning of cardiac structures.
