Heart Attack In Your Dogs

To me, dogs are the best kind of animals in the world. That’s why I really love having one in my house and want to learn everything about him.

I find that dogs have some things in common with humans concerning heart diseases i.e. obesity, old age and diabetes.

For young dogs, heart attacks can cause congenital abnormalities. Meanwhile, older dogs can suffer from a hardened plaque of fats which stops the flow of blood to the myocardium and leads to a heart attack. Diabetic and obese dogs are at a greater danger of coronary artery obstruction. So, they will suffer from the failing of heart muscles which occurs in congestive heart failure.

Find out some possible symptoms

Of course, your beloved dog cannot explain what he is suffering. That’s why you need to know the signs and get them treated as soon as possible. If your dog has a heart attack, he will display some of following symptoms:

  • Pain in breathing
  • His eyes might get drowsy
  • ​Physical ache due to pain in the center of the chest
  • ​Difficulty in moving or standing due to pain in forelimbs
  • He might try to crane and stretch his neck sideways

You should know that there are two kinds of congestive heart failure (CHF) in dogs: left-sided CHF and right-sided CHF.

Here are some of the main symptoms.

Left-sided CHF

  • Coughing
  • Fainting
  • Quick breathing
  • Intolerance to exercise
  • Pain in breathing

Right-sided CHF

  • Coughing
  • Pain in breathing
  • Intolerance to exercise
  • Swelling of the limbs
  • Swollen abdomen due to fluid buildup

If your dog is inactive, sad and has body swelling, persistent coughing and fatigue, it points out the risks of heart disease and potential heart failure. If you find these signs, please ask for help from the veterinarian to receive proper treatment.

What cause?

Cardiomyopathy, arrhythmia, heart-worm, inflammation of the pericardium, degeneration of heart valves and congenital heart defects are the most common causes of congestive heart failure. Large breeds of dogs such as Boxers, Scottish Deerhounds, Dobermans, Irish Wolfhounds and Great Danes can get heart disease more easily than smaller ones.

How about diagnosis and treatment?

The veterinarian will use the stethoscope to check heartbeats and diagnose congestive heart failure in dogs. Additionally, he can use an X-ray, echocardiogram, electrocardiogram and measure blood pressure to examine heart’s condition.

Depending on the heart failure’s cause, a suitable treatment plan will be chosen. You should bring your dog to the hospital to keep him under medical examination. Thoracentesis will be performed to take away the accumulated fluid from the lungs. Your dog is treated with digoxin, nitroglycerine paste and angiotensin converting enzyme inhibitor drugs and fed nutritional supplements along with a low sodium diet.

The fact is that your dog needs as much attention and care as a person does, particularly when he gets dangerous and risky symptoms of a heart attack. So, please bring him to get checked out quickly and help him to feel better soon and healthy again.
