Heart murmurs in dogs can be a serious health issue and proper dietary change is essential for their wellbeing. As a pet owner, it is important to understand what kind of food is best suited for dogs with heart murmurs, and what nutrients they require.

Here we will explore the best diet for dogs with heart murmurs that will help ensure a healthier and longer life:

What is a heart murmur?

A heart murmur is an abnormal sound heard between heartbeats. Murmurs are caused by turbulent blood flow, which can be the result of a variety of factors, including congenital defects, valve diseases, infections or anemia. Heart murmurs can range from mild to severe, and some may require medical treatment or dietary modifications to protect the pet’s health.

The best diet for dogs with a heart murmur depends on the severity of the condition and should always be discussed with a veterinarian. Generally speaking, most pet owners should strive to feed their pet high-quality food that contains more calories than average and is enriched with omega fatty acids to help nourish and strengthen the heart muscle. A low-sodium diet may be beneficial for some pets with a heart murmur as well. Dogs prone to weight gain should also be fed calorie-controlled food or in smaller portions throughout the day in order to avoid stressing the heart further.

Symptoms of heart murmur

Symptoms of heart murmur typically vary depending on the severity of the condition. A common sign that your dog may have a heart murmur is a loud, abnormal “whooshing” sound that can be heard through a stethoscope. Additionally, your dog may also be exhibiting other signs such as coughing, fatigue, lethargy and difficulty breathing. Depending on the cause of the heart murmur and if it worsens over time, your dog may develop congestive heart failure or sudden collapse.

In order to help prevent or manage your pup’s condition, it is important to switch your dog to a diet that meets their unique needs. This includes avoiding foods high in fats and sodium while providing appropriate levels of Omega-3 fatty acids, antioxidants and protein. By providing a nutritionally balanced diet for dogs with heart murmurs, you can help them live longer and healthier lives!

Diet Considerations

For dogs with heart murmurs, a nutrient-dense diet is essential for maintaining health. Food with healthy fats, complex carbohydrates, and minimal amounts of sodium and refined sugar should be avoided. Protein sources should be low in fat and processed with minimal salt. Supplements can also be used to support heart health.

Let’s take a look at some specific dietary considerations:


Protein is an essential element for dogs with heart murmurs. Because of a heart murmur, your pup may not be able to exercise as much, or at all. As a result, they need a higher protein diet to help them maintain their muscle mass and energy levels. Meat based proteins are the most beneficial and are the best choice for your pup’s diet. Examples of sources of high-quality proteins include chicken, fish, eggs, yogurt, and cottage cheese. Be sure to choose leaner cuts as fatty meats can lead to weight gain and further strain on the heart.

It is recommended that an adult dog weighing 30-60 pounds should consume 18-30 percent of their daily caloric intake from protein; while an adult dog weighing more than 60 pounds should consume 16-25 percent of their daily caloric intake from protein. If you are unsure about how much protein your pup should receive in their diet it is best to consult with your veterinarian for advice tailored specifically for them.

Fats and Oils

Fats and oils are essential components of a dog’s diet, even when they have a heart murmur. Omega-3 fatty acids are especially important for canines with cardiovascular issues. Oils like salmon oil, flaxseed oil, and krill oil are excellent sources of Omega-3s. Additionally, they help reduce inflammation and can improve the function of the cardiovascular system.

Not all fats and oils are beneficial for dogs with heart murmurs though. Saturated fats should be avoided as much as possible because they can cause plaque buildup in the arteries, which is a risk factor for cardiac disease in dogs. Therefore, high-quality animal or plant-based oil sources such as olive oil or coconut oil should be chosen to keep fat intake healthy.


Carbohydrates are an important part of the diet for dogs with Heart Murmur. They provide energy and are sources of essential vitamins and minerals. When choosing carbohydrates for your dog, select ones that have a low glycemic index, as they can help regulate blood sugar levels.

Sources of carbohydrates to consider include oats, brown rice, barley, quinoa and sweet potatoes. Avoid potatoes, white breads and other highly processed grains; these can cause unhealthy spikes in blood sugar levels. Additionally, avoid feeding your dog food items such as table scraps or sugary treats that are high in carbohydrates but low in nutritional value.

Feeding the right type of carbs can help promote a healthy diet for dogs with heart murmur while reducing their risk of developing diabetes or other health conditions related to poor nutrition.

Vitamins and Minerals

Vitamins and minerals are essential nutrients that help support a healthy immune system, normal growth and development, as well as metabolic processes. When it comes to dogs with a heart murmur, vitamins and minerals are an important part of their diet. Vitamins such as Vitamin A, B-complex and E are beneficial for dogs with heart murmurs because they can reduce inflammation and stress on the heart.

Additionally, specific minerals such as zinc, copper, iron and magnesium have been found to be beneficial in managing symptoms of heart murmurs in dogs. Zinc is beneficial for the proper functioning of the immune system, while copper helps with cell growth and iron helps to prevent anemia from developing in dogs with heart murmurs. Finally, magnesium has been found to be beneficial for reducing inflammation associated with congestive heart failure in some cases. Therefore, owners should focus on ensuring their dog’s diet contains all essential vitamins and minerals to support their dog’s overall health.

Types of Food

When it comes to choosing the best diet for a dog with a heart murmur, there are various types of food available to suit their needs. It is important to select an appropriate diet which is low in sodium and fat, and high in fibre and protein.

Some of the most popular food types for dogs with heart murmurs include:

  • Dry kibble
  • Wet canned food
  • Home-cooked meals

Let’s explore the different types of food further.

Dry Dog Food

Dry dog food is the most common type of dog food that owners feed their pets. It usually comes in the form of pellets, and can be supplemented with a variety of wet foods or treats, as well as fresh fruits and vegetables.

Dry dog food is an excellent choice for dogs with heart murmur because it contains more proteins than carbohydrates, which can help reduce stress on the heart. Additionally, dry food typically contains more vitamins and minerals than canned food does since it’s not cooked at high temperatures. Furthermore, dry food is usually packed in sealed bags which helps to preserve its freshness for longer periods of time.

However, feeding too much dry food without adequate hydration can lead to health problems such as dehydration or constipation so always make sure your pup stays hydrated when feeding them dry dog food!

Wet Dog Food

Wet dog food, also known as canned or moist dog food, is usually high in moisture content and specifically designed to provide complete nutrition for dogs. Wet dog food is available in several different forms, including pate and stew-style.

Dogs with a heart murmur need a diet that is high in quality protein and contains low-fat content. This type of diet offers the best nutrition for their hearts and overall health benefits.

Wet dog foods are often more palatable than dry kibble so can be better suited for senior and picky eaters. Unfortunately, wet foods do not last as long throughout the day as dry kibble but it can help keep them hydrated when transitioning from kibble to wet or mixed diets. Aside from providing proper nutrition, wet food also offers higher levels of essential fatty acids which help:

  • Improve brain function
  • Develop healthy skin and coat
  • Maintain joint mobility
  • Support a strong immune system

Homemade Dog Food

Homemade Dog Food is a great option for any pup, but it is especially beneficial for dogs with heart murmurs. Dogs with heart murmurs are often prescribed diets that are lower in calories and fat, as well as free of certain proteins that may exacerbate symptoms. Therefore, creating your own tailored diet at home gives you control over what goes into your pup’s food and allows you to better meet their specific nutritional needs. It is important to note that homemade diets should be formulated by a veterinarian or other qualified animal nutritionist to ensure they are balanced.

Homemade dog food can be cooked or served raw, although cooked meals tend to be easier to digest. When feeding homemade meals, always provide fresh ingredients like lean meats and vegetables alongside supplements like vitamins and minerals in order to provide complete nutrition for your pup. This way, you can enjoy the satisfaction of making your pup’s food while also ensuring they get the best possible nutrition.

Feeding Guidelines

Proper nutrition is important for any dog, but even more so for dogs with heart murmurs. Feeding your dog the right diet can help keep their heart healthy and reduce the risk of complications that can occur with this condition.

In this article, we’ll look at some tips on what to feed your dog with a heart murmur:

Quantity of food

When caring for a dog with a heart murmur, it is important to provide the correct quantity of food. Feeding too much or too little can put additional strain on the heart.

The ideal amount of food for a dog with a heart murmur is calculated by their body weight and activity level. Generally, dogs should be fed 1-1.5% of their bodyweight in food per day, divided into two meals if possible. For example, if you have a 10-pound poodle with a heart murmur, they should get between 0.1 and 0.15 pounds (or 6-10 ounces) of food per day—about 4 ounces at breakfast and 4 ounces at dinner time.

It is also important to provide high quality dog food that is naturally nutrient dense such as grain free diets with added supplements like omega-3 fatty acids which can reduce inflammation in the body and help support the heart. Providing regular exercise for your pup will also help keep their weight in check and put less strain on their cardiovascular system.

Frequency of meals

The frequency of meals for a dog with heart murmur depends on the type and severity of the condition. Generally, the heart murmur is mild and does not require any dietary changes. In those cases, it is recommended that you feed your dog twice a day with high-quality food.

If the heart murmur is moderate or severe, your veterinarian may recommend limiting the food intake to once a day or even less than once a day. The goal of this dietary regimen is to reduce stress on the heart by minimizing meal-related fluid accumulation in the lungs and airway caused by eating large meals at once. Additionally, spreading out its energy throughout the day instead of being used all at once during one big meal may also reduce stress on your pup’s heart as well as help manage weight if needed.

Avoiding overfeeding

Avoiding overfeeding is an important part of managing a dog with heart murmur. Dogs with this condition can be prone to developing obesity and other secondary problems, so careful monitoring of their calorie intake is necessary for proper health maintenance. Feed your dog thoughtfully and take into account their age, activity level, and existing conditions.

The most important aspect of a dog’s diet is the quality of their food. The right nutrients in the right amounts are essential for optimal health in all life stages. Feeding your pup a commercial dog food intended for their life stage provides the nutrients they need to stay healthy while meeting the specific nutrient requirements associated with heart murmur.

When selecting a commercial diet, look at ingredient labels to ensure they contain high-quality proteins and healthy fats as well as fiber-rich carbohydrates like whole grains. Avoid foods high in unhealthy fats or added sugars.


Diet is an important factor for all animals, and that especially goes for dogs with heart murmurs. Supplements can help provide an additional layer of support for your pet’s wellbeing, and can also be used to add helpful nutrients to their regular diet.

To determine the best supplements for a dog with a heart murmur, it is important to review the dietary needs of your pet and the potential benefits of adding specific supplements:

Omega-3 fatty acids

Omega-3 fatty acids are essential to a dog’s diet, especially for dogs with heart murmur. Omega-3 fatty acids have anti-inflammatory properties, which can help reduce the inflammation in the heart caused by the murmur. They are also important for the development and maintenance of the immune system and other body functions.

Omega-3 fatty acids can be found in fish oils, such as salmon oil, and flaxseed oil, as well as in other supplements such as krill oil or cod liver oil. Additionally, some omega-3 fatty acid sources that are specific to dogs include egg yolks, canola oil, and pumpkin seed meal.

It is important to ensure your dog has an adequate intake of omega-3 fatty acids from their diet or from supplements so they can maintain a healthy heart function despite their diagnosis.

Vitamin E

Vitamin E is an antioxidant that helps fight harmful free radicals, which may lead to cell damage and inflammation. It is also known for helping to prevent heart disease, arthritis and cancer in dogs.

When managing a dog with a heart condition, it’s important to ensure your pet gets enough vitamin E through their daily diet. Vitamin E deficiencies can further the cardiac damage and increase risk of stroke or heart attack in those affected.

Natural sources of vitamin E include:

  • Nuts
  • Seeds
  • Leafy vegetables
  • Eggs
  • Fish
  • Oils

Food manufacturers also fortify foods with synthetic versions of vitamin E (alpha-tocopherol). Supplements are also available if you feel your dog’s diet is lacking in natural sources of this important nutrient. You should consult with your veterinarian before introducing any supplements into your pet’s diet so they can recommend the proper dose and formulation for your pup’s individual needs.


Taurine is an essential amino acid found in the canine body, which helps regulate cellular functions, including those that affect the heart. It can also support healthy development of the nervous system and eyesight.

Research has shown that dogs with a heart murmur often have lower levels of taurine in their bodies. Adding a taurine supplement to your dog’s diet can help address this deficiency and potentially support the health of your pup’s heart.

Taurine does not occur naturally in the food we feed our dogs, so it must be added through supplements. Look for a supplement containing 500 mg of taurine per serving and follow package instructions when giving to your dog.


After careful assessment of the available evidence it is found that diets that are low in sodium and fat are the most beneficial for dogs with heart murmur. These diets contain the correct balance of nutrients and vitamins to ensure that the dog is not at risk of developing further cardiac problems. Furthermore, due to the nature of these diets, they are unlikely to cause further health problems such as obesity.


The most important dietary change when managing a dog with heart murmur is the reduction of sodium intake. This can be achieved by avoiding processed foods, commercial pet foods, and table scraps. Good alternatives include fresh fruits and vegetables, homemade meals made with low-sodium broth and lean proteins, plus whole grains like quinoa or oats.

It’s also important to monitor your pup’s weight—keeping them at a healthy weight reduces their risk of developing congestive heart failure due to overexertion.

Finally, if your pup has an underlying condition such as mitral valve disease or congestive heart failure, it’s essential that you work closely with your veterinarian for the best possible diet for your dog. With the right diet modifications, along with regular exercise and medication throughout life as necessary, dogs with heart murmurs can lead full lives!

Final Thoughts

When it comes to caring for a dog with a heart murmur, the right diet is key. It is important to be sure that the dog’s diet is low in sodium, fat and cholesterol and high in fiber.

The best diets for dogs with heart murmurs include:

  • Fresh lean meats
  • Fresh fruits and vegetables
  • Whole grain cereals and pastas
  • Proteins from beans and nuts
  • Small amounts of healthy fats from flaxseed oil or fish oil supplements

Additionally, many veterinarians recommend feeding your pet wet food as opposed to dry food because wet food contains more moisture which can help support overall heart health. Finally, it’s important to provide plenty of clean water throughout the day so that your pet can stay hydrated and healthy.

With a proper diet and some careful planning you can give your furry friend the best chance of living a long and happy life.
