What is heart failure?

Heart failure refers to the impossibility of an organ, in this case the heart, to fulfill the proper functions that allow the normal development of the organism. Thus, a heart with heart failure is unable to pump the necessary blood throughout the body.

There are different heart diseases that dogs can suffer, framed according to whether they are congenital or acquired with age. The passage of time usually worsens the cardiac situation, causing greater complications that put the dog’s life at risk.

Risk factor’s

Dogs that meet one or some of the characteristics described below are more likely to have heart disease:

  • Dogs with a genetic history of heart problems.
  • Some breeds, such as: Mastiff, Boxer, Doberman, Cocker Spaniel, Bullterier, Dalmatian, Great Dane, Saint Bernard, and Giant Schnauzer.
  • Elderly dogs. If your dog has been more than 7 years old, it is very likely that he has heart problems. In general, all elderly dogs have some form of heart disease. Likewise, larger dogs, as they age at a faster rate, have a greater possibility of suffering these pathologies earlier.
  • Small dogs. Mini-sized dogs are also not spared, as they are more prone to heart valve degeneration and endocardiosis.

Swelling of the abdomen

Another sign that we can see is swelling in the area of ​​our dog’s belly, as a result of the accumulation of blood in the area.

Fainting

By not being able to pump blood well to all parts of the body, the blood supply is unable to spread effectively through all parts of the body, such as the brain. This causes, in addition to weakness, habitual fainting.

Vomiting

Cardiovascular diseases in dogs

Heart attacks, infections or cardiac tumors are very rare. However, there are some other very common heart conditions among the dogs.

Canine filariasis or heartworm disease

Filariasis or heartworm disease is a very serious pathology caused by the bite of a mosquito. When bitten, worm larvae enter the dog’s body and reproduce in the dog’s heart and lungs.

Pericarditis

Pericarditis is the name given to inflammation of the pericardium. With this disease, this membrane stores more serum than normal, causing pressure, swelling, and inflammation of the heart.

Cardiomyopathy or dilated cardiomyopathy

When a dog is diagnosed with dilated cardiomyopathy, the walls of the heart muscle are unable to contract strongly. This causes a build-up of pressure and blood volume and subsequent muscle dilation.
