Dogs with a family history of heart disease are more likely to develop heart problems themselves, with a study showing that 30% of dogs with a family history of heart disease will develop the condition.
A dog's diet plays a crucial role in maintaining heart health. Feeding a balanced diet that includes omega-3 fatty acids, such as those found in fish oil, can help reduce inflammation and promote cardiovascular wellness.
Regular exercise is also essential for heart health. Dogs that are physically inactive are more likely to develop heart disease, with one study showing that dogs that exercised for less than 30 minutes a day were 2.5 times more likely to develop heart disease than dogs that exercised for more than 30 minutes a day.
Maintaining a healthy weight through a combination of diet and exercise is also vital for heart health. According to the American Heart Association, dogs that are overweight or obese are at a higher risk of developing heart disease.
DCM
DCM can cause a dog's heart to dilate, resulting in an enlarged heart that struggles to pump blood effectively.
This can lead to heart valves leaking and a buildup of fluids in the abdomen and chest.
A buildup of fluids can ultimately lead to congestive heart failure and death.
The FDA is investigating the connection between DCM and grain-free pet food.
Many dog breeds, who are unusual candidates for DCM, are being affected by this connection.
Causes and Conditions
Heart disease is a common condition in dogs, affecting approximately one-third of all dogs over the age of 10. Small dog breeds are generally more at risk of heart disease.
Dog breed is a significant factor, with certain breeds like Labrador Retrievers, Great Danes, and Irish Wolfhounds being more prone to DCM. Infections and viruses, such as heartworm or parvovirus, can also cause heart disease or vasculitis.
Obesity is a major contributor to heart disease in dogs, as it puts unnecessary strain on the heart. A healthy diet is crucial in preventing obesity and heart disease.
Common lifestyle choices that can lead to heart disease in dogs include overfeeding, which can lead to weight gain and obesity. Low taurine levels can also be a contributing factor, especially in dogs eating diets low in meat.
Some ingredients in dog food have been linked to DCM, including legumes, peas, and lentils. Dry dog foods are the most common type of dog food reported in DCM cases.
Congenital conditions, such as Congestive Heart Failure, Canine Dilated Cardiomyopathy, and Pulmonic Stenosis, are present from birth and can result from a breed's predisposition or a condition passed down from the parents.
Acquired conditions, such as Canine Valvular disease, Arrhythmias, and Pericardial disease, develop over time due to normal wear and tear, aging, infections, toxin exposure, or nutritional factors.
Some common heart conditions in dogs include Canine Dilated Cardiomyopathy, Canine Valvular disease, and Arrhythmias. These conditions can be caused by a variety of factors, including genetics, nutrition, and infections.
Here are some other causes of Congestive Heart Failure (CHF):
- Defects in the walls of the heart
- Congenital cardiac defects
- Arrhythmias
- Narrowing of major blood vessels
- Heartworms
- Accumulation of fluid in the pericardium (sack around the heart)
- Infection (endocarditis)
- Tumors or cancer
Symptoms and Detection
Symptoms of dog heart disease can be subtle and may take time to develop. Chronic coughing, irregular breathing, and loss of energy are just a few of the worrisome symptoms that may indicate heart disease in dogs.
Some common symptoms include lethargy, weakness, and exercise intolerance, as well as shortness of breath or difficulty breathing, which may be accompanied by fluid buildup. Fainting or collapse, chronic coughing, and regularly elevated heart rate are also potential signs of heart problems in dogs.
Here are some key symptoms to watch out for:
- Lethargy/weakness/exercise intolerance
- Difficulty with or discontinuing exercise
- Shortness of breath or difficulty breathing possibly accompanied by fluid buildup
- Fainting/collapse
- Chronic coughing
- Regularly elevated heart rate
Early detection is crucial in treating heart disease in dogs. A cardiac examination can help diagnose heart disease, and may include procedures such as a physical exam, ultrasound, blood pressure test, electrocardiogram, X-rays, and blood analysis.
Symptoms of Problems
If your furry friend is showing any of the following symptoms, it's crucial to get them checked out by a vet as soon as possible.
Chronic coughing is a common symptom of heart disease in dogs, and it can be a sign that something is seriously wrong. Irregular breathing, loss of energy, and fainting or collapsing are also red flags that need to be addressed.
Loss of appetite and fluctuating weight are other signs that your dog's heart may be in trouble. Struggling to exercise and restlessness are also symptoms of heart disease that you shouldn't ignore.
Swelling of the abdomen or paws can be a sign of fluid buildup in the body, which is a common symptom of heart disease. Dogs with heart problems may also have difficulty sleeping peacefully.
Here are some of the key symptoms of heart problems in dogs:
- Lethargy/weakness/exercise intolerance
- Difficulty with or discontinuing exercise
- Shortness of breath or difficulty breathing possibly accompanied by fluid buildup
- Fast breathing during dormancy (not panting)
- Fainting/collapse
- Chronic coughing
- Regularly elevated heart rate
These symptoms can be a sign of a serious underlying condition, so it's essential to get your dog checked out by a vet as soon as possible.
Murmurs
Heart murmurs can be a concerning sign in dogs, indicating turbulent blood flow or vibrations of heart structures. In many cases, heart murmurs are caused by mitral regurgitation, a valve disease that affects the mitral valve.
If your vet diagnoses a heart murmur in your dog, they may recommend heart health support supplements to help manage the condition. These supplements can be a useful addition to your dog's treatment plan.
A heart murmur can be a sign of underlying heart disease, such as valvular disease, which accounts for approximately 80 percent of cases in dogs. Mitral valve disease is the most common type of valvular disease, occurring when the mitral valve leaks.
Left-sided heart failure can occur when the mitral valve leaks, causing blood to back up into the lungs and leading to symptoms like coughing and difficulty breathing. Right-sided heart failure, on the other hand, can cause congestion and fluid accumulation in the abdomen.
An enlarged heart in dogs can be a sign of underlying heart disease, such as pericardial effusion, dilated cardiomyopathy, or valvular heart disease. If you notice your dog having trouble lying down or getting comfortable, it could be a sign of an enlarged heart.

Nutrition
A healthy diet is one of the most important factors in preventing disease, and heart healthy nutrition is not just about one factor, but the overall healthiness of the diet and portion sizes a dog is fed.
Preventing overfeeding and weight gain is crucial for your dog to have a healthy body and heart. A balanced, fresh food diet with meats, veggies, and starches provides a balanced serving of heart healthy nutrients for your dog.
Grain-free dog foods typically contain large levels of legumes, lentils, and potatoes, which may be connected to cases of DCM. However, studies have shown that these foods are not only non-toxic and safe for your dog to eat, they provide essential nutrients when consumed in reasonable quantities.
Look for balance in your dog's food and check out the manufacturer for their nutritional expertise and tight quality control standards. The recipe is more important than the brand, so take a look at the individual recipes rather than focusing on the brand name.

Here are some key things to consider when choosing a dog food:
Most types of heart disease cannot be cured, but they can usually be managed with medication, nutrition, and lifestyle changes.
Prevention and Treatment
Prevention and treatment of dog heart disease are crucial to maintaining your furry friend's health. A well-balanced diet rich in nutrients, meat, and Omega-3 fatty acids is the best preventative measure against heart disease in dogs.
To prevent heart disease, feed your dog a low-fat diet, as excessive fat can raise cholesterol levels and increase the risk of strokes or heart disease. Low sodium is also essential, as high sodium can raise blood pressure and strain the heart.
A healthy diet should include Taurine, an amino acid that is synthesized in a dog's body from meat. L-carnitine, found naturally in animal-based protein sources, may be helpful in reducing weight in overweight dogs and treating DCM and other heart diseases. Omega-3 fatty acids can stabilize heart muscle cells and are found in seafood, flaxseed oil, and green leafy vegetables.
Vitamin C and Vitamin E may also reduce the risk of a heart attack, although more research is needed to confirm this. Exercise is also crucial for a healthy dog, but if your dog has heart disease, limit strenuous activity and monitor them closely.
If your dog is diagnosed with heart disease, work closely with your veterinarian to create a treatment plan that improves their quality and length of life. This may involve prescription medicines, dietary adjustments, and even surgical intervention. A veterinary cardiologist can provide guidance on nutrition, medication, and activity to manage heart disease.
Available Treatments
Your veterinarian will likely recommend an angiotensin-converting enzyme inhibitor, or ACE inhibitor, to help reduce stress on your dog's heart. This medication works to relieve pressure and blood volume.
Beta-blockers, nitroglycerine, and digitalis can help reduce symptoms and improve your dog's quality of life. A diuretic may also be prescribed to manage any fluid accumulation around the lungs.
A veterinary cardiologist may prescribe medications to help remove fluids and slow the progression of congestive heart failure. They can also recommend an appropriate amount of exercise or a low-sodium diet to reduce pressure on the heart.
In some cases, DCM can be reversed if caused by a taurine deficiency. This is a rare exception, but with proper veterinary care and medication, many dogs with DCM can go on to live and enjoy life for many more years.
The following medications may be prescribed to manage heart disease in dogs:
- ACE inhibitors to reduce stress on the heart
- Beta-blockers to reduce symptoms and improve quality of life
- Nitroglycerine to reduce symptoms and improve quality of life
- Digitalis to reduce symptoms and improve quality of life
- Diuretics to manage fluid accumulation around the lungs
Preventative Measures
Feeding your dog a healthy diet is crucial to preventing heart disease. A well-balanced diet rich in nutrients, meat, and Omega-3 fatty acids is the best preventative measure against heart disease in dogs.
You should talk to your veterinarian about any dietary changes for your dog. They can help you determine the best diet for your furry friend.
A low-fat diet is essential, as too much fat in the diet can raise a dog's cholesterol level and increase their risk of strokes or heart disease.
Low sodium is also important, as a diet high in sodium can raise a dog's blood pressure and strain their heart.
Taurine is a crucial amino acid that dogs need to synthesize from the meat they consume. Make sure your dog is eating a diet with enough meat to allow them to create sufficient taurine.
Here are some essential nutrients to look for in your dog's diet:
- Low Fat
- Low Sodium
- Taurine
- L-carnitine
- Omega-3 Fatty Acids
- Vitamin C and Vitamin E
A diet with high-quality, animal-based protein is key to providing your dog with the best nutrients for their optimal health.
Stages and Failure
Congestive heart failure in dogs can be a challenging condition to navigate, but understanding its stages can help you and your veterinarian provide the best possible care.
There are four stages of congestive heart failure in dogs, and they can be identified based on the presence of clinical signs and the dog's response to cardiac medications. The first stage, Stage A, is characterized by a high risk of developing heart disease based on age and breed, but no overt clinical signs.
As the condition progresses, dogs may develop a heart murmur, which can be detected with a stethoscope, indicating Stage B. Dogs in Stage C are showing signs of heart disease and are responsive to cardiac medications. Unfortunately, there is no cure for heart failure in dogs, and early detection and proper management are crucial to improving a dog's prognosis and quality of life.
Here's a breakdown of the stages:
The prognosis for dogs with congestive heart failure varies depending on factors such as age, severity of the condition, medications, and underlying medical conditions. In general, dogs with CHF can live anywhere from 6 months to 1 1/2 to 2 years with proper management.
Stages of
The stages of congestive heart failure in dogs are a crucial aspect to understand when it comes to managing and treating the condition.
There are different stages of congestive heart failure in dogs, and they're determined by the severity of the symptoms and the dog's overall health.
The first stage, Stage A, is characterized by a high risk of developing heart disease based on age and breed, but no overt clinical signs are present.
In Stage B, a heart murmur can be heard with a stethoscope, but the dog may not be exhibiting clinical signs of heart failure.
Stage C dogs are showing signs of heart disease and are responsive to cardiac medications.
These stages help veterinarians determine the severity of the condition and develop a treatment plan accordingly.
Here's a summary of the stages:
Each stage represents a progression of the condition, and understanding these stages can help dog owners and veterinarians work together to manage and treat congestive heart failure.
What Causes Failure?
Failure can be caused by a lack of clear goals, which can lead to a lack of direction and focus. This can result in a project or endeavor going off track and ultimately failing.
Poor planning and a failure to anticipate potential obstacles can also contribute to failure. This can be seen in the case of the Wright brothers' first powered flight, where they didn't anticipate the challenges of landing safely.
Lack of resources, including time, money, and personnel, can also be a major factor in failure. Without sufficient resources, a project may not have the necessary support to succeed.
Inadequate risk assessment and a failure to identify potential pitfalls can also lead to failure. This can be seen in the case of the Titanic, where the ship's builders and owners failed to identify the risks of hitting an iceberg.
Overconfidence and a failure to adapt to changing circumstances can also contribute to failure. This can be seen in the case of the dot-com bubble, where companies failed to adapt to the changing market and ultimately went bankrupt.
