Did you know that heart diseases are one of the leading causes of death in dogs? Just like in humans, these conditions can cause a lot of damage to the organ and lead to serious health complications. If you think your dog might be suffering from heart disease, it’s important to seek veterinary help as soon as possible. In this post, we’ll discuss the most common causes of heart disease in dogs, as well as their symptoms and treatment options. Keep reading for more information!
Heart Diseases In Dogs?
Heart disease is one of the leading causes of death in dogs. It can affect any breed of dog at any age but is most common in older dogs. There are many different types of heart disease, but they all involve some type of problem with the heart muscle or valves. Heart disease can be congenital (present at birth) or acquired (develops later in life).
Types Of Heart Diseases In Dogs
There are many different types of heart disease that can affect dogs. Some of the more common types include:
1. Congenital Heart Disease
Congenital heart disease is a type of heart defect that is present at birth. It can be caused by a number of different things, including genetic defects, infections, or problems with the development of the heart in the womb. Congenital heart disease can sometimes be corrected with surgery, but it often cannot be cured and will require lifelong treatment.
2.Valvular Heart Disease
Valvular heart disease is a problem with one or more of the valves in the heart. The valves are responsible for regulating blood flow through the heart and when they don’t work properly, it can lead to heart disease. Valvular heart disease is often seen in older dogs and is a common cause of congestive heart failure.
3. Dilated Cardiomyopathy
Dilated cardiomyopathy is a type of heart disease that occurs when the heart muscle weakens and enlarges. This makes it difficult for the heart to pump blood effectively and can lead to congestive heart failure. Dilated cardiomyopathy is most common in large breeds of dogs, but it can occur in any breed.
4. Arrhythmogenic Right Ventricular Cardiomyopathy (ARVC)
ARVC is a type of heart disease that affects the right ventricle of the heart. In ARVC, the muscle tissue in the right ventricle is replaced by scar tissue. This can cause heart rhythm problems and eventually lead to heart failure. ARVC is most common in certain breeds of dogs, including Boxers, Cocker Spaniels, and Doberman Pinschers.
5. Heartworm Disease
Heartworm disease is a serious and potentially fatal condition caused by parasitic worms that live in the heart and lungs of dogs. The worms are transmitted through mosquito bites and can cause damage to the heart, lungs, and other organs. Heartworm disease is preventable with regular medication, but it can be difficult to treat once it has developed.

Symptoms Of Heart Disease In Dogs
The symptoms of heart disease vary depending on the type of heart disease present. However, some common symptoms include:
–Coughing:
One of the most common symptoms of heart disease in dogs is a dry, hacking cough. This is often worse at night or during exercise.
-Exercise Intolerance:
Dogs with heart disease often become tired more easily and have difficulty exercising. They may also pant excessively or have trouble catching their breath.
-Weight Loss:
Many dogs with heart disease lose weight even though they have a good appetite.
-Lethargy:
Dogs with heart disease often seem tired and listless. They may sleep more than usual and have less energy.
-Collapse:
In some cases, dogs with heart disease may suddenly collapse due to an irregular heartbeat or other problems. If your dog collapses, it is important to seek emergency veterinary care immediately.
Causes Of Heart Disease In Dogs
There are many different causes of heart disease in dogs. Some of the more common causes include:
– genetics:
Some dogs are born with heart defects that can lead to heart disease.
– infections:
Heartworm disease and other infections can damage the heart and lead to heart disease.
– age:
Older dogs are more likely to develop heart disease.
– diet:
Dogs who eat a poor-quality diet or are overweight are more likely to develop heart disease.
– trauma:
Injury to the chest can cause problems with the heart and lead to heart disease.
-Pregnancy:
Pregnancy can sometimes cause heart problems in dogs.
-Poor Nutrition:
Dogs who do not receive proper nutrition are more likely to develop heart disease.
Diagnosing Heart Disease In Dogs
Heart disease can be difficult to diagnose because the symptoms can be vague and nonspecific. Your veterinarian will start with a complete history and physical examination. They will then likely recommend some or all of the following tests:
-Blood work:
Blood tests can help to check for anemia, infections, and other problems that can cause heart disease.
-Chest X-ray:
A chest X-ray can show the size and shape of the heart and lungs and can help to diagnose heart disease.
-Echocardiogram (heart ultrasound):
An echocardiogram is a type of ultrasound that uses sound waves to create a picture of the heart. It can be used to evaluate the structure and function of the heart and to diagnose heart disease.
-Electrocardiogram (ECG):
An ECG is a test that measures the electrical activity of the heart. It can be used to diagnose heart rhythm problems and other problems that can cause heart disease.
-Holter monitor:
A Holter monitor is a type of portable ECG that can be worn for 24 hours or more. It can be used to diagnose heart rhythm problems that only occur occasionally.
-Stress test:
A stress test is a type of exercise test that is often used to diagnose heart disease. During a stress test, your dog will be monitored while walking on a treadmill or riding a bike. The goal is to make your dog’s heart work hard enough to reveal any problems.
-Cardiac catheterization:
Cardiac catheterization is a test that is sometimes used to diagnose heart disease. During the procedure, a long, thin tube called a catheter is inserted into the heart through an artery in the leg. The catheter can be used to measure the pressure in the heart and to take pictures of the heart.

Treating Heart Disease In Dogs
The treatment of heart disease depends on the underlying cause. Some types of heart disease can be cured, while others can only be managed. Treatment options include:
-Medication:
Medications are often used to treat heart disease. Commonly used medications include diuretics, ACE inhibitors, beta-blockers, and digoxin.
-Diet:
Dogs with heart disease may need to be fed a special diet. Your veterinarian can recommend a diet that is right for your dog.
-Weight management:
Dogs who are overweight or obese are more likely to develop heart disease. Maintaining a healthy weight can help to prevent or treat heart disease.
-Exercise:
Exercise is important for all dogs, but it is especially important for dogs with heart disease. Exercise helps to maintain a healthy weight, strengthens the heart muscle, and improves circulation.
-Surgery:
Surgery may be necessary in some cases of heart disease. Surgery can be used to repair defects in the heart, remove tumors, or relieve pressure on the heart.

Preventing Heart Disease In Dogs
There are several things you can do to help prevent heart disease in your dog:
-Feed a high-quality diet:
Feeding a high-quality diet is one of the most important things you can do for your dog’s health. Choose a diet that is appropriate for your dog’s age, weight, and activity level.
-Maintain a healthy weight:
Keeping your dog at a healthy weight is important for overall health and can help to prevent heart disease.
-Exercise regularly:

-Visit the veterinarian regularly:
Regular checkups are important for all dogs, but they are especially important for dogs with heart disease. Your veterinarian can detect heart problems early and start treatment before the disease becomes severe.
-Avoid tobacco smoke:
Tobacco smoke contains harmful chemicals that can damage the heart and lungs. If you smoke, do not allow your dog to be exposed to secondhand smoke.
-Prevent infections:
Infections can cause inflammation and damage to the heart. Keep your dog up to date on vaccinations and take steps to prevent flea, tick, and heartworm infections.
Prognosis
The prognosis for dogs with heart disease depends on the underlying cause. Some types of heart disease can be cured, while others can only be managed. In general, the earlier heart disease is diagnosed, the better the prognosis. Dogs with mild heart disease may have a normal life expectancy, while dogs with severe heart disease may only live for a few months. If you think your dog may have heart disease, make an appointment with your veterinarian as soon as possible. Early diagnosis and treatment are essential for the best possible outcome.
