According to 2010 research, omega-3 fatty acids EPA and DHA may also help to stabilize heart muscles and reduce the risk of cardiac events in animals with chronic heart conditions. Your vet may recommend supplements to ensure your dog gets these nutrients.

How To Choose The Right CHF Dog Food

When choosing CHF food for your dog, you want to look for foods that are age and size-appropriate.

Foods made using natural, tasty, digestible, and healthy ingredients are essential, as is avoiding foods with cheap, unhealthy filler ingredients such as artificial additives and wheat. Be sure to look out for allergen-free food if your dog has allergies or sensitivities and always read customer reviews before buying food online.

Look for products from trusted brands and recipes formulated and tested by vets or approved/recommended by official bodies. You can also check labels and product listings for organic and ethically sourced ingredients if that’s important to you.

How To Change Your Dog’s Diet

If your dog has a sensitive stomach, you may want to transition their diet gradually. Start by filling their bowl with 3/4 of the old food and 1/4 with the new food. After a couple of days, make it half and half, then after a couple more days, make it 3/4 new food, 1/4 old food. Finally, make it so it’s 100% new food.

If your dog’s stomach has a poor reaction at any point during the transition, go back a step and wait a couple more days.

What Is Congestive Heart Failure?

Congestive heart failure (CHF) is a condition that affects the heart’s ability to pump blood. If a dog has CHF, his body isn’t going to function as well as it should. It is not a disease, but most often the result of heart disease.


CHF can be genetic or age-related, but poor diet and exercise, illness, stress, and physical trauma can exacerbate it. There are several causes of CHF in dogs, but the most common ones are a leaky mitral valve and dilated cardiomyopathy. It’s also more likely to affect older dogs and larger breeds like Great Danes and Saint Bernards

There are two types of heart failure; acute and chronic, meaning that it either happens suddenly (acute) or over time (chronic). There are also four stages of congestive heart failure; A, B, C, and D; which range from a high risk of developing heart failure to advanced heart failure.


The symptoms of heart failure in dogs include coughing, increased heart rate, trouble breathing or losing breath easily, trouble settling down at night, a lesser desire to exercise and play, and tiring out easily.

Advanced symptoms include a swollen belly, fainting, gums and tongue turning blue/grey, and weight loss.

Dogs with symptoms of heart failure should be examined by a vet as soon as possible because it is as serious as it sounds. Vets may listen to your dog’s heartbeat and perform several tests and scans, including a chest X-ray and blood testing.

Treatment & prognosis

Unfortunately, congestive heart failure is a progressive condition. There is no cure at present, but there are treatments that can prolong your dog’s length and quality of life for as long as possible. Most dogs diagnosed with CHF live for around 3 years.

The type of treatment your vet prescribes will depend on what type and stage of heart failure your dog has. All require lifestyle changes including a low salt diet and limited exercise, to reduce strain on the heart and fluid build-up in the body. As well as ongoing medications like diuretics and inhibitors. In some cases, surgery may also be necessary. You should monitor your dog’s symptoms and attend regular vet visits as well.


Although you can’t always prevent congestive heart failure, studies have shown that there is a link between grain-free diets and heart disease in dogs.
