Canine Heart Disease: Symptoms, Causes, and How to Protect Your Dog

Does your four-legged friend have canine heart disease?

While this may be concerning, it’s important to remember that this condition is usually manageable, especially when detected early.

By understanding the signs, you can significantly improve your dog’s quality of life. Early detection is essential, and thankfully, advancements in technology, like innovative health monitoring systems such as Maven Pet, can play a vital role in identifying subtle changes that might indicate heart issues.

In this article, we delve into canine heart disease, its most common causes, how to prevent it, and how Maven Pet can help you ensure your pet’s best health.

What is Canine Heart Disease?

Canine heart disease encompasses a range of conditions that affect the heart’s ability to function effectively. It disrupts the normal flow of blood, which can lead to complications.

Vets often categorize heart disease as either congenital (the dog is born with the condition) or acquired (developed over time). If left untreated, canine heart disease can progress to a more severe stage, known as congestive heart failure.

Common Causes of Heart Disease in Dogs

As mentioned above, heart disease in dogs can be congenital or acquired. Let’s go through some specific causes of heart disease in dogs:

  • Genetics: Certain breeds, such as Cavalier King Charles Spaniels, Boxers, and Doberman Pinschers, have a higher predisposition to specific types of heart conditions.
  • Age-related degeneration: Just like humans, dogs can experience a weakening of their heart valves as they age, a common cause of acquired heart disease.
  • Heartworm disease: This preventable parasitic infection can cause significant and lasting damage to the heart and lungs.
  • Poor diet and obesity: Excess weight puts extra strain on a dog’s heart, increasing the risk of developing heart problems.

Symptoms of Canine Heart Disease

Recognizing the early signs of heart disease in dogs is crucial for early intervention. Keep an eye out for these symptoms:

  • Persistent coughing, particularly after exercise or when resting.
  • Lethargy and weakness.
  • Difficulty breathing or an increased respiratory rate, even at rest.
  • Fainting or collapsing episodes.
  • Swollen belly, which can be a sign of fluid buildup.

Dog Heart Failure Symptoms: When It Becomes Critical

When canine heart disease progresses to heart failure, the symptoms become more severe. Recognizing these dog heart failure symptoms can be decisive for getting veterinary attention and saving your dog’s life: 

  • Severe breathing difficulties or wheezing.
  • Bluish gums, indicating a lack of oxygen in the blood.
  • Extreme fatigue, even during very mild activities.
  • Swelling in the legs and abdomen due to fluid retention.

How to Prevent and Manage Canine Heart Disease

If you’re wondering how to prevent heart disease in dogs, here are some steps you can take to help prevent and manage this condition:

  • Regular vet checkups: These are essential for early detection. Your vet can listen for heart murmurs and perform other tests to assess your dog’s heart health.
  • Heart-healthy diet and weight management: Feeding your dog a balanced diet and maintaining a healthy weight reduces the strain on their heart.
  • Routine exercise: Regular, appropriate exercise (tailored to your dog’s age, breed, and health) supports cardiovascular health. Talk to your vet to determine the right amount and type of exercise for your dog.
  • Heartworm prevention: Consistent use of preventative medication administered by your vet is crucial to protect your dog from this dangerous parasite.
