Common Heart Health Issues in Dogs

Heart disease is a common health issue in dogs, with several types of heart diseases that can affect them. Some of the most common heart health issues in dogs include Dilated Cardiomyopathy (DCM), Mitral Valve Disease (MVD), Aortic Stenosis (AS), and Pericardial effusion. DCM is a condition where the heart muscle becomes weak and enlarged, leading to poor pumping function. MVD is a condition where the mitral valve of the heart degenerates, leading to leakage of blood and reduced heart efficiency. Aortic Stenosis is a common congenital heart defect in large breed dogs, typically caused by a ridge or ring of fibrotic tissue condition in the subaortic region. Pericardial effusion is an acquired cardiovascular disease in dogs, where excessive fluid accumulates within the pericardial sac, affecting the heart’s ability to pump effectively.

Common Breeds Predisposed to Heart Disease

Certain dog breeds are more predisposed to specific heart issues due to inherited traits and genetic factors. Some of these breeds include Boxers, Cocker Spaniels, Doberman Pinschers, Great Danes, Irish Wolfhounds, Saint Bernards, Cavalier King Charles Spaniels, Chihuahuas, Dachshunds, Miniature Poodles, Pomeranians, Shih-Tzus, Small Terrier Breeds, Boxers, Bullmastiffs, German Shepherds, Golden Retrievers, Newfoundlands, Rottweilers, Afghan Hounds, Boxers, Boston Terriers, Bulldogs, French Bulldogs, German Shepherds, Golden Retrievers, Salukis, and Weimaraners. It’s important to note that not all dogs of these breeds will develop heart disease, but they may have a higher genetic predisposition to certain heart conditions.

Risk Factors for Canine Heart Disease

Several factors can increase the risk of heart disease in dogs. These include age, excess weight and obesity, poor diet lacking essential nutrients, lack of exercise, heartworm disease, hypertension (high blood pressure), thyroid disease, infections, congenital heart defects, exposure to toxins and medications, and Cushing’s Disease (Hyperadrenocorticism). It’s important for dog owners to be aware of these risk factors and take preventive measures to maintain their dog’s heart health.

Breeds Prone to Heart Health Issues

Certain dog breeds are more predisposed to heart health issues due to genetic factors and inherited traits. Some of these breeds include:

Boxers, Cocker Spaniels, Doberman Pinschers, Great Danes, Irish Wolfhounds, Saint Bernards

These large breed dogs are more prone to dilated cardiomyopathy (DCM), a condition where the heart muscle becomes weak and enlarged, leading to poor pumping function.

Cavalier King Charles Spaniels, Chihuahuas, Dachshunds, Miniature Poodles, Pomeranians, Shih-Tzus, Small Terrier Breeds

These small breed dogs are predisposed to mitral valve disease (MVD), a condition where the mitral valve of the heart degenerates, leading to leakage of blood and reduced heart efficiency.

Boxers, Bullmastiffs, German Shepherds, Golden Retrievers, Newfoundlands, Rottweilers

These breeds are more prone to aortic stenosis (AS), a common congenital heart defect in large breed dogs, typically caused by a ridge or ring of fibrotic tissue condition in the subaortic region.

Afghan Hounds, Boxers, Boston Terriers, Bulldogs, French Bulldogs, German Shepherds, Golden Retrievers, Salukis, Weimaraners

These breeds are predisposed to pericardial effusion, an acquired cardiovascular disease in dogs, where excessive fluid accumulates within the pericardial sac, affecting the heart’s ability to pump effectively.

It’s important for owners of these breeds to be aware of the potential for heart health issues and to ensure their dogs receive regular health checks to monitor and manage any potential heart conditions.

Breeds Less Prone to Heart Health Issues

Some dog breeds are less predisposed to heart disease compared to others. While no breed is immune to heart issues, the following breeds are known to have a lower genetic predisposition to certain heart conditions:

• Labrador Retrievers
• Border Collies
• Poodles
• Beagles
• Australian Shepherds

While these breeds may have a lower risk, it’s important to note that any dog, regardless of breed, can develop heart disease. Regular health checks and maintaining a healthy lifestyle are crucial for all dogs to ensure their heart health is monitored and maintained.

Factors Contributing to Heart Health Issues in Dogs

Environmental Factors

Environmental factors, such as exposure to second-hand cigarette smoke, can have a negative impact on a dog’s heart health. Second-hand smoke can lead to respiratory issues and cardiovascular problems in dogs, increasing their risk of developing heart disease.

Age

As dogs age, they become more susceptible to heart health issues. Senior dogs, typically those over the age of 5-8 for very large/giant breeds, 7-10 for medium-sized breeds, and 9-12 for small breeds, are at a higher risk of developing heart disease. Regular health checks and screenings are important for early detection and management of any potential heart issues.

Excess Weight & Obesity

Just like in humans, excess weight and obesity can put a strain on a dog’s heart, increasing the risk of developing heart disease. Maintaining a healthy weight through proper diet and regular exercise is crucial for the overall heart health of dogs.

Poor Diet

A poor diet lacking essential nutrients can impact a dog’s heart health and contribute to the development of heart disease. Feeding dogs a balanced and nutritious diet is essential for maintaining their overall health, including their heart health.

Lack of Exercise

Insufficient physical activity can lead to obesity and cardiovascular health issues in dogs. Regular exercise is important for maintaining a healthy heart and overall well-being in dogs.

Heartworm Disease

While heartworm disease is not common in the UK, dogs traveling abroad or those adopted from overseas may be at risk. Heartworms can have a detrimental effect on a dog’s heart health, making preventive measures and screenings essential for dogs at risk of exposure.

Hypertension (High Blood Pressure)

High blood pressure can put added stress on a dog’s heart and lead to the development of heart disease. Monitoring a dog’s blood pressure and addressing any hypertension issues is important for maintaining their heart health.

Thyroid Disease

Thyroid imbalances, such as hypothyroidism or hyperthyroidism, can affect a dog’s heart function. Regular thyroid screenings and proper management of thyroid disease are crucial for maintaining a dog’s heart health.

Infections

Certain infections, such as bacterial endocarditis, can lead to heart disease in dogs. Preventative measures and prompt treatment of infections are important for safeguarding a dog’s heart health.

Congenital Heart Defects

Some dogs are born with structural abnormalities in their hearts that can lead to heart disease. Early detection and management of congenital heart defects are essential for ensuring a dog’s heart health.

Understanding and Monitoring Heart Health in Canines
