Buyer’s Guide: Selecting the Best Dog Food for Heart Disease

Now you’ve seen our top dog food choices for canines with heart disease, but you might be wondering how we choose these five foods over all the others.

For us, it all starts with an understanding of heart disease in dogs. What exactly is heart disease and what are its effects for our pooches?

Then, it comes down to the type of nutrients that will give our dogs the best fighting chance against heart diseases of any type. We look for the food that’s packed with the most beneficial and health-boosting nutrients that are specifically formulated to provide the nutrients that a dog with heart disease needs.

Don’t worry, we’re not going to leave you in the dark. If this all sounds like information that you need to know as the owner of a dog with heart disease, that’s because it is. And to make it easy for you to digest, we’ve included it all in this short buyer’s guide.

What is Heart Failure?

  • Heart failure doesn’t always happen in dogs with heart disease. However, dogs with heart disease are at a much higher risk of heart failure as this is the final stage of severe heart disease.
  • Like it sounds, heart failure is when the heart fails. It can be caused by a number of processes including fluid buildup, decreased blood flow, or extremely low blood pressure.
  • Many dogs with heart disease will never experience heart failure, but only dogs with heart disease are at risk since it is caused by severe heart disease.

What is Canine Heart Disease?

  • We’ve all heard of heart disease, but what exactly is it?
  • Actually, heart disease is a pretty wide-ranging term. Pretty much any abnormality of the heart can be called heart disease. These abnormalities can be physical, functional, congenital, acquired, etc. They can even be short or long in duration. Basically, anything wrong with your heart can fall under the umbrella of heart disease.

Signs Your Dog Might Have Heart Disease

  • It can be terrifying to find out that your beloved best friend has heart disease. But if you catch it early on, your chances of mitigating the disease and helping your dog to live a long, healthy, happy life are much better.
  • Of course, if you want to catch heart disease early, you’re going to need to know what to look for. The following five symptoms are often the first early indicators that your dog may have heart disease. Keep an eye out for these symptoms and if you see your dog exhibiting any of them, it might be time to get some professional help.

Difficulty Breathing

  • Having a hard time breathing is often one of the first symptoms that dogs with heart disease will display. This might present itself as hard, labored breathing that seems to require a lot of force, or you might see them breathing rapidly.
  • If you only see your dog breathing hard occasionally or after physical exertion, then there’s probably nothing to worry about. A dog that has difficulty breathing due to heart disease will usually have trouble breathing all or most of the time.
  • You might notice your dog’s posture change in an attempt to make it easier to breathe. They may stretch their necks out and spread their legs wide apart. Since most dogs with heart disease find it more difficult to breathe lying down, you’ll likely notice your dog sitting or standing for long periods instead.


  • Many dogs cough for reasons completely unrelated to heart disease. But if your dog has a cough that persists for several days and doesn’t want to dissipate, then it could be due to heart disease.
  • When the heart can’t pump efficiently, fluid can buildup in the lungs causing your dog to cough in an attempt to expel the extra fluid.
  • In some forms of heart disease, the heart actually swells and enlarges. This can cause it to press on your dog’s airways, which can result in continuous coughing.
  • As a general rule, if your dog has a cough that continues for days or weeks, you should take them to the vet. It could very likely be a sign of something much more serious.


  • If you notice that your dog seems to tire out much quicker than they used to, it could be a sign of heart disease. This might be accompanied by more sleeping and resting than usual.
  • You might find that dogs who were excited for playtime or exercise before don’t seem to be interested any longer. This is likely due to the excessive fatigue caused by heart disease.

Changes in Behavior

  • When your dog’s behavior changes, your first thought likely isn’t heart disease. But this disease can have many effects on your dog, including major behavioral changes.
  • Some of the most common changes in behavior that you’re likely to see due to heart disease are changes in eating habits, a loss of desire to play, no longer wanting to participate in activities they enjoy, or seeking isolation.
  • While these types of behavioral changes aren’t enough to diagnose heart disease from, they’re certainly enough to warrant a trip to the vet for further study.

Collapsing or Fainting

  • All of the organs and systems in your dog’s body rely on blood to function. When heart activity decreases because of heart disease, those organs aren’t getting enough blood, which deprives them of vital nutrients such as oxygen. Oxygen deprivation can easily lead to fainting or collapse.
  • The brain also receives reduced blood flow in dogs with heart disease. This alone can result in collapse.
  • For most dogs with heart disease, fainting and collapsing will be triggered by physical activity. If you notice your dog faints when you play with them or take them on a walk, then it’s time to visit the vet.

Seek a Professional Opinion

  • We’ve discussed quite a few of the signs that might clue you into your dog’s growing heart troubles. However, only a trained and qualified veterinarian can diagnose heart disease.
  • Take note of all of the signs and symptoms your dog is displaying. This is all valuable information that can help your vet to correctly diagnose your dog’s health concerns.
  • But that’s not where the vet’s role ends. Your veterinarian can also help you to formulate the ideal diet for your dog to keep them healthy and provide the nutrients they need to fight off heart disease and live a long life.
  • While the foods we picked are some of the best all-around choices for most dogs with heart disease, every case is unique. Your dog may have special needs above and beyond those of other dogs. So, it’s best to get the individualized, specific care that your canine needs from your vet.

Choosing the Best Dog Food for Heart Disease

So, what do the best dog foods for canines with heart disease contain?

These foods are packed with the vital nutrients that will give your dog a fighting chance against heart disease. This includes nutrients like:


Dogs require 22 amino acids to make the proteins that their bodies need for healthy functionality. Naturally, your dog can’t fight off any infectious diseases if its body is struggling just to keep up with its amino acid needs. That’s why the best foods for dogs with heart disease include plenty of protein from diverse, whole-food sources to ensure that your dog is getting all of the amino acids it needs. This allows their body to focus on fighting diseases and getting healthy instead of focusing on finding deficient amino acids.


Antioxidants protect against cellular damage. Any compound can be an antioxidant, including vitamins, minerals, herbs, and more. Some of the most common antioxidants are vitamin C, vitamin E, and beta-carotene. These health-boosting nutrients are great for reducing inflammation and bolstering the immune system.


  • Supplements are concentrated forms of nutrients that are normally consumed through food. But some nutrients are difficult to get in the amounts our dogs need from natural sources alone. This is particularly true when your dog has heart disease and needs high levels of very specific nutrients.
  • For this reason, we prefer foods that are fortified with vital supplements like taurine and l-carnitine. These supplements can help many dogs with different heart concerns, and they’re an extra line of defense for a dog that’s fighting against disease.
You Might Need a Prescription

There’s one thing to keep in mind that you may not have considered. For some of these foods, you’ll actually need a prescription from your vet. This means that your veterinarian will need to provide authorization before you can even get these foods for your dog. While that may seem like overkill, it’s a great way to ensure that only dogs who need the specialized nutrients in such foods will get them.

Final Thoughts

While reviews can be beneficial when finding the right diet for your dog with heart disease, it really comes down to a decision to be made between you and your veterinarian. However, the top pick for dogs with heart disease on our search is the Royal Canin Veterinary Diet Early Cardiac Dry Food, which is a prescription diet.

The budget-friendly pick is the food from Spot & Tango, which provides a subscription service. For a premium product, the Hill’s Prescription Diet h/d Heart Care Chicken Flavor food is another prescription diet that is formulated specifically for dogs with heart disorders.  Our vets recommend that heart patients be on prescription heart foods as a gold standard but your own dog’s vet is best placed to make recommendations tailored to you and your pet so reach out to them to help you make this important decision.
